They are tuned to Arc Audio subwoofer parameters. Internal volume, port dimensions, and cabinet geometry are matched to the Thiele-Small characteristics of Arc Audio woofers at each specific diameter. This produces an enclosure that extracts more output from an Arc Audio driver than a general-purpose box of the same construction. Available in 10 inch and 12 inch sizes across single and dual configurations in both sealed and ported types.\u003c\/p\u003e\n\n\u003ch2\u003eSealed and Ported Options\u003c\/h2\u003e\n\n\u003cp\u003eBoth sealed and ported enclosures are available in this series. The sealed option delivers controlled transient response and a gradual low-frequency rolloff that integrates predictably with most amplifier subwoofer channels. The ported option uses a port tuned to the specific Arc Audio driver size it is built for, extending low-frequency efficiency and increasing SPL output at the tuning frequency. Port dimensions are not generic. They are calculated for the Arc Audio woofer parameters at each diameter.\u003c\/p\u003e\n\n\u003ch2\u003eDado and V-Groove Construction\u003c\/h2\u003e\n\n\u003cp\u003eCabinet panels are joined using Dado and V-Groove cuts, which create interlocking channels at each panel intersection before bonding. This mechanical lock adds shear resistance beyond what adhesive alone provides and maintains panel alignment during assembly and curing. Arc Audio subwoofers are built for sustained high-excursion output, which generates repeated internal pressure cycles. The Dado and V-Groove joint maintains cabinet integrity and internal volume accuracy under those conditions across the life of the install.\u003c\/p\u003e\n\n\u003ch2\u003eDriver Fitment and Mounting\u003c\/h2\u003e\n\n\u003cp\u003eThe single mounting face is sized to each Arc Audio driver diameter, 10 inch and 12 inch, in single and dual configurations. Woofer mounting uses standard screws, which are not supplied. The woofer sits flush against the baffle without a recessed cutout. Confirm screw length against your specific Arc Audio driver's basket depth before install. Screws that are too long risk contacting the voice coil assembly and causing permanent damage to the driver.\u003c\/p\u003e\n\n\u003ch2\u003eTerminal Cup and Finish Options\u003c\/h2\u003e\n\n\u003cp\u003eEach enclosure uses a basic spring-loaded terminal cup that accepts bare wire directly at install. No ring terminals or spade connectors required. The cabinet exterior is available in grey trunkliner or plush black carpet, both standard finish options in the Proline X lineup. Neither finish requires additional treatment before the enclosure goes into the vehicle.\u003c\/p\u003e\n\n\u003ch2\u003eBuild Specification and Series Position\u003c\/h2\u003e\n\n\u003cp\u003eThese enclosures ship without polyfill, prewiring, or rubber feet. Polyfill is excluded to preserve the accuracy of the Arc Audio-specific port tuning and internal volume. Adding fill material to a driver-matched ported enclosure alters the alignment it was built around. This series sits above the standard Performance tier and is the correct choice when the goal is to run an Arc Audio subwoofer in an enclosure built specifically for its parameters, not adapted from a universal design.\u003c\/p\u003e\n\n\u003caside class=\"ai-callout-cta\"\u003e\n\u003cp class=\"ai-callout-label\"\u003eNeed Help With Your Arc Audio Build?\u003c\/p\u003e\n\u003cp\u003eTalk to an SQ-judge tech directly.

The cabinet dimensions, mounting face, and port tuning are calculated for Arc Audio Thiele-Small parameters. If you have a different Arc Audio driver and aren't sure about fit, contact our tech team with the specific model.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between sealed and ported in this series?\u003c\/h3\u003e\n\u003cp\u003eSealed enclosures produce tight, accurate bass with predictable rolloff, ideal for SQ-focused builds and most music genres. Ported enclosures extend low-frequency response and produce noticeably more output at the tuning frequency, ideal for output-priority builds. Both are tuned specifically to Arc Audio driver parameters in this series. The choice depends on your build goals and available enclosure space.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use these enclosures with non-Arc Audio drivers?\u003c\/h3\u003e\n\u003cp\u003eMechanically the cutout dimensions accommodate standard 10 inch and 12 inch drivers, so a different brand could physically mount. However, the internal volume and port tuning are calculated for Arc Audio's specific driver characteristics. Putting a different brand's driver in this enclosure means the alignment is no longer matched, and the driver won't perform as designed. For non-Arc Audio drivers, the standard Performance Series is the better choice.\u003c\/p\u003e\n\n\u003ch3\u003eWhy don't these enclosures include polyfill?\u003c\/h3\u003e\n\u003cp\u003ePolyfill alters the acoustic alignment of a tuned enclosure. Since these boxes are built specifically to Arc Audio driver parameters, adding polyfill changes the tuned alignment they were designed around. The result is reduced output efficiency and a shift in the tuning frequency. The series is shipped without polyfill so the alignment stays intact.\u003c\/p\u003e\n\n\u003ch3\u003eWhat size amplifier do I need for an Arc Audio sub in this enclosure?\u003c\/h3\u003e\n\u003cp\u003eMatch your amplifier's RMS output at your wired impedance to the Arc Audio driver's RMS rating. Arc Audio 10 inch drivers typically run 250 to 500W RMS. Arc Audio 12 inch drivers typically run 350 to 700W RMS. The enclosure doesn't change the power requirement. A monoblock amplifier matched to the driver's RMS rating at the final wired impedance is the standard approach.\u003c\/p\u003e\n\n\u003ch3\u003eDoes the dual configuration require specific wiring?\u003c\/h3\u003e\n\u003cp\u003eDual driver configurations let you wire the two voice coils in series or parallel depending on your amplifier's stable impedance. Two dual 4 ohm Arc Audio drivers in parallel present a 1 ohm load. Two dual 2 ohm drivers in parallel present a 0.5 ohm load (most amps won't handle this). Confirm your amplifier's stable impedance specification before wiring.\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003c\/div\u003e","products":[{"product_id":"proline-x-performance-optimized-sealed-enclosure-for-single12-arc-audio-subwoofers","title":"Proline X Performance Optimized Sealed Enclosure for Single 12\" Arc Audio Subwoofers","description":"\u003ch3\u003eIntroduction\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eExperience the pinnacle of audio performance with the Proline X Enclosure, expertly crafted for your 12\" Arc Audio subwoofer.
