High end car audio from a shop that builds its own enclosures

We manufacture, we do not just resell. Proline X subwoofer enclosures are CNC cut in our own shop in Tullahoma, Tennessee on ShopSabre routers from Langboard Elite MDF. Scott Welch has been in mobile audio since 1985, holds IASCA National and MECA World Sound Quality Championship titles, and has judged SQ competitions since 2019. We are also the Original US Importer of Goldhorn DSP, which means we import, tune, support, and warranty that line directly.

A system where the parts were selected to work together rather than bought individually off spec sheets. In practice that means the subwoofer is matched to an enclosure built for its published Thiele Small parameters, the amplifier is sized to the driver's real RMS handling rather than its peak rating, and a processor corrects for seating position and path length differences. A moderately priced system designed properly will beat an expensive one that was not. Browse the high end car audio catalog for the amplifiers, processors, and drivers we run at the reference end.

Arc Audio, Audiomobile, Audio Wave, Crescendo, Goldhorn DSP, Image Dynamics, JL Audio, Karma Mobile Audio, Prodigy Audio, Stereo Integrity, Tru Technology, US Acoustics, and Wavtech, plus our own Proline X enclosure line. The catalog is deliberately narrow. We stock what we would run ourselves rather than everything a distributor will sell us. The reference tier from those high end car audio brands is collected on one page.

Yes. We build behind-seat direct-fit enclosures for the 2015 to 2023 F-150 and 2017 to 2023 F-250, and for the 2024 to 2026 F-150. Single 10 inch, dual 10 inch, single 12 inch, and passive radiator versions are available, and several ship loaded with the driver already mounted and wired. Check the year range on the listing before ordering, because the cab changed between platforms and the boxes are not interchangeable.

Built to order. Enclosures ship from Tullahoma in 5 to 10 business days, due to current high order volume. Because we run the routers ourselves we can also cut a variant that is not listed, such as a different net volume or a different driver cutout. Call 931-563-5151 to talk through a one off.

Let the driver decide. Divide the driver's free air resonance by its electrical Q, which gives you the efficiency bandwidth product. Under 50 the driver generally wants a sealed box, 50 to 100 works either way, and over 100 it wants a vented box. Sealed gives you a shallower rolloff and better transient behavior in a smaller footprint. Ported gives you more output near the tuning frequency at the cost of box size and a steeper rolloff below it. Our EBP calculator will run the number for you.

If you care about staging and tonal balance, yes. A car puts you off axis from both front speakers with path lengths that can differ by more than a foot, which smears the center image and creates cancellation you cannot EQ away. Time alignment fixes that. Once arrival times are corrected, EQ can address the response problems that are genuinely acoustic. A DSP will usually do more for perceived quality than the same money spent on larger speakers.

Everything ships from our shop at 122 Turkey Creek Church Rd, Tullahoma, TN 37388. In-stock items ship within 1 to 2 business days, and built-to-order enclosures ship in 5 to 10 business days, due to current high order volume. We are reachable Monday through Friday, 9am to 5pm CST, at 931-563-5151 or contact@audiointensity.com.
