A Solo-X wants a large ported cabinet. A CompQ wants a modest sealed box. A CompRT is a shallow driver meant to live behind a seat. We build for all three, and the box you need is decided by the model on the magnet, not by the cone diameter.\u003c\/p\u003e\n\u003ch3\u003eSolo-X: X Series Ported\u003c\/h3\u003e\n\u003cp\u003eThe Solo-X is the competition driver, and it is the reason the \u003ca href=\"https:\/\/audiointensity.com\/collections\/proline-x-professional-series\"\u003eX Series\u003c\/a\u003e exists. These are large ported cabinets built to the same standard as our Professional Series: V-groove and dado joinery, a double-layer baffle at minimum, and threaded inserts matched to the driver's bolt pattern. Volumes run from 0.88 cubic feet for a single 8 up to 10 cubic feet for a dual 15. On the dual builds the quoted figure is the total volume of one shared chamber, which is how a ported enclosure is supposed to work.\u003c\/p\u003e\n\u003ch3\u003eCompQ and Comp VX: Performance Optimized Sealed Wedge\u003c\/h3\u003e\n\u003cp\u003eThese are the sealed wedge boxes for the street drivers, cut to each model's published Thiele-Small parameters. The two lines are not interchangeable even at matching cone sizes. A CompQ 12 gets 1.37 cubic feet while a Comp VX 12 gets 1.00, because the motors and suspensions are different. Same story at 10 inch, where the CompQ takes 0.66 and the Comp VX takes 0.80.

Dropping to 0.80 net raises Qtc to 1.314 and pushes F3 to 39.5 Hz, costing nearly 4 Hz of extension. On the 10 the same proportional reduction costs about 2 Hz. The difference is the Vas: the 12 has 52 liters of compliance and it genuinely uses the air you give it, so the extra two inches of cabinet height here buys something real. Check the arithmetic yourself on our \u003ca class=\"df-link\" href=\"\/pages\/sealed-box-calculator\"\u003esealed box calculator\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eOne thing worth being straight about. With a free air Qts of 0.7235, \u003cstrong\u003esystem Qtc cannot fall below 0.7235 in any sealed enclosure\u003c\/strong\u003e, so this driver is mildly underdamped in every sealed box regardless of size. That is a design characteristic of the CompRT 12, not a limitation of this cabinet. It produces a modest lift near the corner frequency and the punchy, forward presentation the CompRT is known for. If you want the more damped and neutral of the two CompRT sizes, that is the 10 with its 0.618 Qts. The 12 goes deeper, the 10 plays tighter.\u003c\/p\u003e\n\u003cp\u003eFiring down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz, so in car response extends well below the anechoic figure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eDown Fire Construction\u003c\/h3\u003e\n\u003cp\u003eCut with V-groove and dado joinery on our ShopSabre routers from Langboard Elite 3\/4 inch MDF, a dense 48.5 lb\/ft³ board with a 200 psi internal bond and 410,000 psi MOE.

The payoff is bass with zero bloom, kick drums that hit and stop, and a gradual, gentle roll-off that in-vehicle cabin gain fills back in below the knee.

damping is the thing that decides whether a driver wants a vent, and the CompR 10 has more of it than almost anything else in this programme. Qts 0.473 is the third lowest of the twenty-six ten inch cabinets we build, which means the motor is holding the cone still rather than the suspension doing it. A driver damped that hard in a sealed box gives up output for control nobody asked for. In a vented one the port takes over below tuning and the damping stops costing anything.\u003c\/p\u003e\n  \u003cp\u003eTuned to 34.0 Hz in 1.27 cubic feet net it produces 1.50 dB of anechoic passband ripple, the third flattest curve of any ten in the range. That is the low Qts showing up as a measurable result rather than a spec-sheet virtue: a higher-Q motor in the same cabinet would put a bump at tuning that this one simply does not have.\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, 27.29 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 3.00 inches wide by 6.25 tall, 18.8 square inches, and it exits\n  through a 22.1 square inch mouth. Air leaves at 16.2 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.

That is the highest mechanical Q of all sixty-two drivers we have modelled in this chassis, and it is on a shallow-mount ten, which is where you would least expect to find it. Mechanical Q measures how little the suspension loses to friction and hysteresis. A high figure says the spider and surround are returning almost all of the energy the motor puts into them instead of turning it into heat.\u003c\/p\u003e\n  \u003cp\u003eLow mechanical loss is worth more in a vented box than a sealed one, because around tuning the cone barely moves and the port carries the output. Anything the suspension wastes at that point is wasted for nothing. Tuned to 33.5 Hz the cabinet reaches an anechoic F3 of 30.1 Hz from a driver only 3.44 inches deep, and the mouth runs a relaxed 13.0 metres per second.\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, 28.37 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 3.00 inches wide by 6.25 tall, 18.8 square inches, and it exits\n  through a 26.5 square inch mouth. Air leaves at 13.0 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 33.5 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.

anechoically this is the weakest ten in the programme. Its F3 of 34.5 Hz is the highest of all twenty-six, which on a spec comparison makes it look like the one to skip.

free-air resonance is high for a ten in this company, and 19.6 litres of Vas is stiff. On paper that combination reads as a driver that does not want a vent at all. What it actually produces, in 1.26 cubic feet tuned to 35.0 Hz, is 1.34 dB of anechoic passband ripple: the second flattest curve of any ten we build and the sixth flattest of all sixty-two cabinets in the programme.\u003c\/p\u003e\n  \u003cp\u003eA stiff suspension and a strong motor is the combination that makes a vented alignment behave, because both of the things that put a peak at tuning are absent. Bl 18.4 on a ten is a serious motor, and it is doing the work that a larger, softer driver would ask the cabinet to do. The result is a passband you can EQ against rather than around.\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, 28.10 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 3.25 inches wide by 6.25 tall, 20.3 square inches, and it exits\n  through a 26.5 square inch mouth. Air leaves at 13.3 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 35.0 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 28 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.

F3 of 29.6 Hz from a ten inch driver is not common, and among the seven Kicker tens that solve in this chassis the CompVR is the only one that gets there.

That is the choice this driver rewards. The port moves 12.4 metres per second, comfortably inside the chuff threshold, so the reach is not being bought with a strained vent.\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.

Air leaves at 12.4 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.

drivers are usually stiff, because there is no room behind the cone for a suspension with any travel in it. The CompRT 12 is 3.75 inches deep and has 59.2 litres of Vas, which makes it the third most compliant of the twenty-two shallow-mount drivers in this programme and more compliant than most conventional twelves. Its mechanical Q of 12.85 is the second highest of all sixty-two.\u003c\/p\u003e\n  \u003cp\u003eCompliance and low mechanical loss together are what let a shallow driver tune low. This one sits at 32.5 Hz in 1.44 cubic feet with an anechoic F3 of 33.8 Hz and 1.18 dB of in-car spread, eighth flattest of the twenty-six twelves. The port runs 12.8 metres per second, well inside the chuff threshold.\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, 28.31 inches of centreline path.\u003c\/p\u003e\n  \u003cp\u003eThe channel is 3.25 inches wide by 6.25 tall, 20.3 square inches, and it exits\n  through a 26.5 square inch mouth. Air leaves at 12.8 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 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. What the voice coil can dissipate as heat is a separate ceiling set by Kicker, not by\n  the cabinet.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"df-section\"\u003e\n  \u003ch3\u003eCut for this driver, not for a catalogue\u003c\/h3\u003e\n  \u003cdiv class=\"df-grid\"\u003e\n    \u003cdiv class=\"df-card\"\u003e\n\u003ch4\u003eMounting\u003c\/h4\u003e\n\u003cp\u003eCut to Kicker's published 11.000 inch cutout with a\n    13.500 inch ring bonded under the baffle.

high. It is the third highest of the twenty-six twelve inch cabinets in this programme, and conventionally a driver in that region is a sealed-box driver. Ported alignments want damping and this one arrives without much. What it has instead is 531 square centimetres of cone behind a motor only 4.375 inches deep, which is a combination worth building around even if it takes work.\u003c\/p\u003e\n  \u003cp\u003eThe work is airspace. 1.54 cubic feet net in an 18.00 inch cabinet is the joint largest in the programme, and it is what stops a lightly-damped driver putting a peak at tuning. Tuned to 35.0 Hz it lands at an anechoic F3 of 35.0 Hz and 2.17 dB of in-car spread, which for a shallow twelve with this much Qts is a genuinely good result.\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, 27.71 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 15.4 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 35.0 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 28 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.

The Down Fire version reads 1.50.
