We build a different series against each rung rather than dropping every driver into the same cabinet.\u003c\/p\u003e\n\n\u003ch3\u003eIDQ Series: Performance Optimized\u003c\/h3\u003e\n\u003cp\u003eThe IDQ 10 and IDQ 12 are the mid tier of the Image Dynamics range and they get Performance Optimized boxes. Single 10 inch starts at $249.99, single 12 inch at $299.99, with dual configurations at $329.99 and $389.99. Each is available box only or with the driver added in dual 2 ohm or dual 4 ohm, which is the simplest route if you have not bought the sub yet.\u003c\/p\u003e\n\n\u003ch3\u003eIDMAX Series: Professional Series\u003c\/h3\u003e\n\u003cp\u003eThe IDMAX is the sound quality benchmark of the range and it gets the Professional Series treatment. Sealed boxes for the IDMAX 10 at $249.99, IDMAX 12 at $299.99 and IDMAX 15 at $379.99, plus a dual IDMAX 10 at $319.99. Loaded versions with the driver already mounted and wired run $699.99 for the 10 and $799.99 for the 12.\u003c\/p\u003e\n\n\u003ch3\u003eNot Sure Which Driver You Have\u003c\/h3\u003e\n\u003cp\u003eIDQ and IDMAX are not interchangeable in the same box. They differ in compliance and resonance, which changes the net volume each one wants. Check the badge on the motor or the model number on the frame before ordering, and if the box you need is not listed, we cut to spec.\u003c\/p\u003e\n\n\u003caside class=\"ai-callout-spec\"\u003e\n\u003cp class=\"ai-callout-label\"\u003eQuick Reference: Image Dynamics Enclosure Mapping\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eID Series:\u003c\/span\u003e Performance or Performance Down Fire\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eIDQ Series:\u003c\/span\u003e Performance Optimized\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eIDMAX Series:\u003c\/span\u003e Professional Series\u003c\/p\u003e\n\u003c\/aside\u003e\n\n\u003ch2\u003eSingle, Dual, or Loaded\u003c\/h2\u003e\n\n\u003cp\u003eMost of this range comes three ways and the right choice usually comes down to what you already own.\u003c\/p\u003e\n\n\u003ch3\u003eBox Only\u003c\/h3\u003e\n\u003cp\u003eShips prewired to the terminal cup, ready for the driver you already have. This is the majority of what we sell here and it is the right pick if the sub is already in the vehicle or on the way.\u003c\/p\u003e\n\n\u003ch3\u003eLoaded\u003c\/h3\u003e\n\u003cp\u003eDriver mounted, wired, and sealed against the baffle at our bench. You still need an amplifier, and for a single sub a monoblock is the correct topology. Loaded builds remove the two things installers most often get wrong: gasket seal and coil wiring.\u003c\/p\u003e\n\n\u003ch3\u003eDual Driver\u003c\/h3\u003e\n\u003cp\u003eTwo drivers sharing one cabinet. Available across both IDQ sizes and on the IDMAX 10. Worth confirming your amplifier is stable at the final impedance your wiring produces before you commit.\u003c\/p\u003e\n\n\u003ch2\u003eHow These Are Built\u003c\/h2\u003e\n\n\u003cp\u003eLangboard Elite 3\/4 inch MDF, CNC cut on ShopSabre routers in Tullahoma, Tennessee. Every enclosure is internally braced and prewired to a Proline X ABS and carbon fiber terminal cup with stainless steel hardware. Sealed variants ship with polyfill installed.\u003c\/p\u003e\n\n\u003cp\u003eWarranty follows the series. Professional Series enclosures, which covers the IDMAX boxes, carry a 2 year limited warranty on craftsmanship and materials. Performance Optimized enclosures, which covers the IDQ boxes, carry 1 year.\u003c\/p\u003e\n\n\u003cp\u003eVolume is calculated from the driver's measured Thiele Small parameters rather than approximated. For the reasoning behind sealed against ported for a given driver, run the numbers on our \u003ca href=\"https:\/\/audiointensity.com\/pages\/ebp-calculator\"\u003eEBP calculator\u003c\/a\u003e, or read \u003ca href=\"https:\/\/audiointensity.com\/pages\/qes\"\u003ewhat Qes means\u003c\/a\u003e if you are working from a spec sheet.\u003c\/p\u003e\n\n\u003cp\u003eIf you are still choosing a driver, the \u003ca href=\"https:\/\/audiointensity.com\/collections\/image-dynamics\"\u003efull Image Dynamics range\u003c\/a\u003e covers subwoofers, amplifiers and speakers.

Tell us the model and the space you have.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-contact-phone\"\u003e931-563-5151\u003c\/span\u003e\u003cspan class=\"ai-contact-divider\"\u003e|\u003c\/span\u003e\u003cspan class=\"ai-contact-email\"\u003econtact@audiointensity.com\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/aside\u003e\n\n\u003ch2\u003eFrequently Asked Image Dynamics Enclosure Questions\u003c\/h2\u003e\n\n\u003ch3\u003eCan I use an IDQ box for an IDMAX?\u003c\/h3\u003e\n\u003cp\u003eNo. The IDQ and IDMAX have different compliance and resonance, which means they call for different net volumes. Putting an IDMAX in a box sized for an IDQ will not damage the driver, but it will not perform the way it was engineered to either. Order the box built for the model you own.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between the Performance Optimized and Professional Series boxes?\u003c\/h3\u003e\n\u003cp\u003eBoth are cut from the same Langboard Elite MDF on the same routers. Professional Series is the higher construction tier and is matched to the IDMAX, which is the flagship driver in the Image Dynamics range. Performance Optimized is matched to the IDQ. The tier follows the driver rather than being a separate choice you make.\u003c\/p\u003e\n\n\u003ch3\u003eDo you sell enclosures for the ID Series?\u003c\/h3\u003e\n\u003cp\u003eThe entry level ID Series maps to our Performance and Performance Down Fire enclosures rather than the two series listed on this page. Contact us with your model and we will point you to the right box or cut one to spec.\u003c\/p\u003e\n\n\u003ch3\u003eShould I buy the box loaded or empty?\u003c\/h3\u003e\n\u003cp\u003eEmpty if you already own the driver. Loaded if you are buying both together and want the gasket seal and coil wiring done at our bench rather than in your driveway. Loaded builds are available for the IDMAX 10 and 12 and for both IDQ sizes.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need an amplifier?\u003c\/h3\u003e\n\u003cp\u003eYes. These are passive enclosures with no amplification built in. For a single subwoofer a monoblock matched to the driver's final impedance is the standard approach. If you are keeping the factory head unit you will also need a line output converter or a DSP with speaker level inputs.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the warranty?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the series. The IDMAX boxes are Professional Series and carry a 2 year limited warranty on craftsmanship and materials. The IDQ boxes are Performance Optimized and carry 1 year. The Image Dynamics driver itself carries its own manufacturer warranty separately.\u003c\/p\u003e\n\n\u003c\/div\u003e","products":[{"product_id":"professional-series-enclosure-image-dynamics-idmax-10-sealed-box","title":"Professional Series Sealed 10\" Enclosure | Image

It's about each driver doing less work to produce the same output. Two 10s playing at moderate excursion will always sound cleaner than a single 10 working hard to hit the same SPL. Lower distortion, lower thermal compression, and a presentation that sounds easier on the ears even at high listening levels.\u003c\/p\u003e\n    \u003cdiv class=\"po-grid\"\u003e\n      \u003cdiv class=\"po-card\"\u003e\n        \u003ch4\u003eTwice the Cone Area\u003c\/h4\u003e\n        \u003cp\u003eTwo IDQ10 V4s deliver roughly 2x the radiating area of a single 10.

drivers are usually where a ported build stops making sense: too little cone area to move the air, too little compliance to tune low. The ID8 V4 is the exception because of one number. It resonates at 31 Hz free-air, which is lower than most twelves manage, and a motor that reaches that far down can be vented properly rather than as a gesture.\u003c\/p\u003e\n  \u003cp\u003eTuned to 34.0 Hz in 1.04 cubic feet it reaches an anechoic F3 of 30.2 Hz. That is deeper than three of the twelve inch cabinets in this same range, from a driver with less than half their cone area. It is also the smallest box we build ported, at 12.50 inches of external depth, which is the whole reason to want an eight in the first place.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eThe port is the product\u003c\/h3\u003e\n  \u003cp\u003eA ported cabinet is easy to get wrong and the failure is audible. This one uses an\n  L-wrap slot port: a single folded wall running down the long side of the box past the\n  woofer ring, turning once through a faceted 90 degree bend, and opening through a\n  chamfered corner. One wall, one bend, 27.82 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 2.50 inches wide by 6.25 tall, 15.6 square inches, and it exits\n  through a 17.7 square inch mouth. Air leaves at 10.8 metres per second at the tuning\n  frequency, against the 17.0 metre per second threshold where a slot port starts to\n  chuff. The bend is faceted rather than square because the inner corner of a 90 degree\n  turn is where flow separates, and a sharp corner there is what you hear.\u003c\/p\u003e\n  \u003cdiv class=\"df-highlight\"\u003e\n    \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X\n    cabinet we build. It does not go in this one. Damping material in a vented box\n    changes the effective volume the port is tuned against, which moves the tuning\n    frequency away from the 34.0 Hz the port length was cut for. Adding it does not make\n    a ported box sound like a bigger ported box; it makes it a mistuned one.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eRun a subsonic filter\u003c\/h3\u003e\n  \u003cp\u003eThis is not optional advice on a vented enclosure. Below tuning the port stops\n  loading the cone and excursion climbs without limit toward DC, so a 27 Hz high-pass at\n  24 dB per octave is part of the specification rather than a refinement of it. Set it\n  and the same cabinet takes substantially more power for the same cone travel. Leave it\n  out and the driver runs out of suspension on material you cannot hear.\u003c\/p\u003e\n  \u003cp\u003eEvery wattage on the Performance Graphs tab is a mechanical limit, not an electrical\n  one: it is the power at which the cone reaches the end of its linear travel in this\n  box.

flattest cabinet in the entire Proline X ported range. Across 25 to 60 Hz, with cabin gain applied, it holds 0.63 dB of variation. The next best is 1.5, and most of the range sits between 2 and 5. That is not a marketing number: it is the solver own objective, measured the same way on every enclosure we build.\u003c\/p\u003e\n  \u003cp\u003eIt happens because the driver and the cabin want the same thing. A 32 Hz motor with a 0.73 Qts and 37 litres of compliance, vented at 33.0 Hz into 1.41 cubic feet, produces a response whose natural rise sits exactly where a car own gain starts falling away. Nothing is being corrected or compensated. The two curves simply add up flat.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eThe port is the product\u003c\/h3\u003e\n  \u003cp\u003eA ported cabinet is easy to get wrong and the failure is audible. This one uses an\n  L-wrap slot port: a single folded wall running down the long side of the box past the\n  woofer ring, turning once through a faceted 90 degree bend, and opening through a\n  chamfered corner. One wall, one bend, 30.48 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 3.50 inches wide by 6.25 tall, 21.9 square inches, and it exits\n  through a 26.5 square inch mouth. Air leaves at 9.0 metres per second at the tuning\n  frequency, against the 17.0 metre per second threshold where a slot port starts to\n  chuff. The bend is faceted rather than square because the inner corner of a 90 degree\n  turn is where flow separates, and a sharp corner there is what you hear.\u003c\/p\u003e\n  \u003cdiv class=\"df-highlight\"\u003e\n    \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X\n    cabinet we build. It does not go in this one. Damping material in a vented box\n    changes the effective volume the port is tuned against, which moves the tuning\n    frequency away from the 33.0 Hz the port length was cut for. Adding it does not make\n    a ported box sound like a bigger ported box; it makes it a mistuned one.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eRun a subsonic filter\u003c\/h3\u003e\n  \u003cp\u003eThis is not optional advice on a vented enclosure. Below tuning the port stops\n  loading the cone and excursion climbs without limit toward DC, so a 26 Hz high-pass at\n  24 dB per octave is part of the specification rather than a refinement of it. Set it\n  and the same cabinet takes substantially more power for the same cone travel. Leave it\n  out and the driver runs out of suspension on material you cannot hear.\u003c\/p\u003e\n  \u003cp\u003eEvery wattage on the Performance Graphs tab is a mechanical limit, not an electrical\n  one: it is the power at which the cone reaches the end of its linear travel in this\n  box.

inches of mounting depth the IDQS8 is the shallowest eight in this programme, and only the Wavtech thinPRO12 mounts shallower in any size. It exists for installations where a conventional eight will not physically fit, and this cabinet exists because a shallow driver still deserves a solved enclosure rather than a universal box.\u003c\/p\u003e\n  \u003cp\u003eTuned to 32.5 Hz in 1.02 cubic feet it reaches an anechoic F3 of 27.9 Hz, the deepest figure of any cabinet in this range. For a driver 3.11 inches deep with 7 mm of one-way travel that is a genuinely surprising number, and it comes from the alignment rather than from the motor: the box is doing work the driver cannot do on its own.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eThe port is the product\u003c\/h3\u003e\n  \u003cp\u003eA ported cabinet is easy to get wrong and the failure is audible. This one uses an\n  L-wrap slot port: a single folded wall running down the long side of the box past the\n  woofer ring, turning once through a faceted 90 degree bend, and opening through a\n  chamfered corner. One wall, one bend, 28.40 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 2.25 inches wide by 6.25 tall, 14.1 square inches, and it exits\n  through a 22.1 square inch mouth. Air leaves at 7.6 metres per second at the tuning\n  frequency, against the 17.0 metre per second threshold where a slot port starts to\n  chuff. The bend is faceted rather than square because the inner corner of a 90 degree\n  turn is where flow separates, and a sharp corner there is what you hear.\u003c\/p\u003e\n  \u003cdiv class=\"df-highlight\"\u003e\n    \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X\n    cabinet we build. It does not go in this one. Damping material in a vented box\n    changes the effective volume the port is tuned against, which moves the tuning\n    frequency away from the 32.5 Hz the port length was cut for. Adding it does not make\n    a ported box sound like a bigger ported box; it makes it a mistuned one.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eRun a subsonic filter\u003c\/h3\u003e\n  \u003cp\u003eThis is not optional advice on a vented enclosure. Below tuning the port stops\n  loading the cone and excursion climbs without limit toward DC, so a 26 Hz high-pass at\n  24 dB per octave is part of the specification rather than a refinement of it. Set it\n  and the same cabinet takes substantially more power for the same cone travel. Leave it\n  out and the driver runs out of suspension on material you cannot hear.\u003c\/p\u003e\n  \u003cp\u003eEvery wattage on the Performance Graphs tab is a mechanical limit, not an electrical\n  one: it is the power at which the cone reaches the end of its linear travel in this\n  box.

mounts in 3.504 inches, the same as its ten inch sibling, but carries 523 square centimetres of cone. More area moving the same 7.5 mm means more displacement out of a chassis that fits the same places, and it is the reason to choose this over the IDQS10 wherever the footprint allows it.\u003c\/p\u003e\n  \u003cp\u003eThe extra cone gets a wider channel to work through: 25.0 square inches, the largest port we cut and shared only with the two IDQ builds, running at 31 percent of its turbulence limit. That is the lowest loading of the three shallow cabinets. In the car it produces 2.6 dB of spread across 25 to 60 Hz, comfortably the flattest result the shallow series manages.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eThe port is the product\u003c\/h3\u003e\n  \u003cp\u003eA ported cabinet is easy to get wrong and the failure is audible. This one uses an\n  L-wrap slot port: a single folded wall running down the long side of the box past the\n  woofer ring, turning once through a faceted 90 degree bend, and opening through a\n  chamfered corner. One wall, one bend, 27.03 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 4.00 inches wide by 6.25 tall, 25.0 square inches, and it exits\n  through a 22.1 square inch mouth. Air leaves at 13.5 metres per second at the tuning\n  frequency, against the 17.0 metre per second threshold where a slot port starts to\n  chuff. The bend is faceted rather than square because the inner corner of a 90 degree\n  turn is where flow separates, and a sharp corner there is what you hear.\u003c\/p\u003e\n  \u003cdiv class=\"df-highlight\"\u003e\n    \u003cp\u003e\u003cstrong\u003eThis enclosure ships dry.\u003c\/strong\u003e Polyfill goes in every sealed Proline X\n    cabinet we build. It does not go in this one. Damping material in a vented box\n    changes the effective volume the port is tuned against, which moves the tuning\n    frequency away from the 36.0 Hz the port length was cut for.

V4 carries 8.071 inches of mounting depth, and that single figure rules it out of our ported Down Fire: the motor would push that cabinet to 8.57 inches tall against a hard 8.50 inch cap. A trunk wedge stands 15 inches tall for a single 12 and takes the motor in depth instead, so this is where the IDMAX12 goes ported. It gets 1.71 cubic feet net, vented at 31.5 Hz, in a cabinet 29 inches wide.\u003c\/p\u003e\n  \u003cp\u003eA 26 Hz free-air resonance on 72 litres of Vas is a motor that wants air and a low vent, and 31.5 Hz is where the in-car curve comes out flattest: 1.38 dB of spread across 25 to 60 Hz on 3.63 dB of anechoic ripple. Tuning lower would trade that for a bloated bottom octave once cabin gain is added; tuning higher gives up the reach the 26 Hz motor is paying for. Image Dynamics' own manual puts the IDMAX12 in a 1.75 cubic foot ported box tuned to 35 Hz for its Universal alignment; this cabinet is 1.85 gross, 1.71 net after the driver, vented 3.5 Hz lower for the in-car curve. The channel runs at 17 metres per second to get there, right at our ceiling, and the mouth carries a 1\/2 inch roundover on all three edges, so the opening at the face is 31 square inches and the air leaves it at 10.7, well under the 17 where a slot port starts to chuff.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eTrunk-load wedge, explained\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThe 20 degree face is the seat side\u003c\/h4\u003e\n\u003cp\u003eA factory rear seat back\n    leans about 20 degrees off vertical.

with an F3 of 32.7 Hz against 37.7 for the Down Fire version of the same driver. The port needs only 15.64 of the 25.43 inches available and runs at 19.3 metres per second in the channel, exactly at its limit for a port this size, 12.0 at the mouth.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eTrunk-load wedge, explained\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThe 20 degree face is the seat side\u003c\/h4\u003e\n\u003cp\u003eA factory rear seat back\n    leans about 20 degrees off vertical.

resonates at 45 Hz on a 0.79 Qts, which sets a floor on what any cabinet can do with it, and the wedge builds to that honestly: 1.28 cubic feet net vented at 35 Hz through a 15.5 square inch port, 30 inches wide, 15.5 tall, 7.62 inches at the top and 13.27 at the base. Image Dynamics' own ported recommendation is 1.5 cubic feet with a 3 inch round port; this cabinet gives the driver twice that port area.\u003c\/p\u003e\n  \u003cp\u003eAn F3 of 38.1 Hz is the honest consequence of a 45 Hz motor and no alignment argues with it. What 35 Hz tuning buys is control: 1.67 dB of anechoic ripple and 2.56 dB of in-car spread across 25 to 60 Hz. If low extension is what you want, the ID10 in this series reaches 32.7 Hz. The port needs 20.55 of the 25.66 inches available and runs at 16.6 metres per second in the channel against a 17.9 limit, 9.9 at the mouth.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eTrunk-load wedge, explained\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThe 20 degree face is the seat side\u003c\/h4\u003e\n\u003cp\u003eA factory rear seat back\n    leans about 20 degrees off vertical.

In the car the spread is 3.83 dB across 25 to 60 Hz, inside the line's 4 dB, because there is little bottom end for cabin gain to exaggerate. This is a fitment cabinet for a shallow install, not a reach cabinet.

Fire caps at 8.50 inches of height and the wedge has no fifteen-inch ported height it fits. The Professional box stands 18 inches tall, flush-mounts the flange in a 2.25 inch baffle built from three 3\/4 inch layers, and gives the motor the depth it needs. It gets 2.72 cubic feet net, vented at 26.5 Hz, in a 36 inch wide cabinet beside the front port.\u003c\/p\u003e\n  \u003cp\u003eImage Dynamics publish a Qts of 0.95 at 30 Hz for the D2 coil, and that figure is genuine: their Qes and Qms reproduce it and the motor constants agree. A driver that damped wants a large box and a low vent, and their own manual says so, recommending 3.0 cubic feet gross at 27 Hz for the Universal alignment. This cabinet lands on it: 4.12 gross, 2.72 net after the driver, port and braces, vented at 26.5 Hz, which is where the in-car curve comes out flattest. Passband ripple sits at 4.46 dB, and that number is the driver's Q rather than the box; tuning higher or lower makes it worse, not better.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eWhat makes it Professional\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eThree-layer baffle, flush mount\u003c\/h4\u003e\n\u003cp\u003eThree layers of 3\/4 inch Langboard Elite make a 2.25 inch\n    front.

The IDMAX15 V4 did not clear the ripple 5.51 dB over 4.5 gate there: the nearest wedge that fits is 24.5 by 11.25 by 17.98 inches with a 23.0 square inch port, and no tuning, width or depth inside that envelope passes.

The IDMAX15 V4 did not clear the ripple 5.51 dB over 4.5 gate there: the nearest wedge that fits is 24.5 by 11.25 by 17.98 inches with a 23.0 square inch port, and no tuning, width or depth inside that envelope passes.
