Quad 10 Inch Subwoofer Boxes

Four Drivers, One Cabinet

Four tens is the highest driver count we cut in a size that still fits a vehicle. It is a little less cone area than three twelves, spread over four smaller cones with less moving mass each.

Every cabinet on this page is sealed and holds four 10 inch drivers, each in its own chamber behind a bonded full-height divider. The driver-matched cabinets are cut from the parameters the driver's maker publishes. Each listing states the net volume for the whole cabinet and the figure per chamber, which is what one driver actually works into.

Sealed quad 10 inch cabinets, wedge, 44 inches wide.

Cut, assembled and finished in Tullahoma, Tennessee. Shipping included.

Driver-matched cabinets are cut from the parameters each driver's maker publishes. Enclosure only unless the listing says loaded.

Quad 10 Inch Subwoofer Box Questions

Do the four drivers share one chamber?

No. Every cabinet on this page splits the volume with bonded full-height dividers, so each driver gets its own sealed air space and its own polyfill. The listing states the total net volume and the figure per chamber.

Is the net volume per driver or for the whole box?

The headline figure is for the whole cabinet. Each listing also gives the per-chamber volume, which is what one driver is working into and the number the alignment was solved from.

How wide is a quad 10 inch box?

Every cabinet here is 44 inches wide. Four 10 inch cutouts plus the baffle material and dividers between them do not fit across less, so there is no narrower version. Measure the narrowest point of your opening at seat-back height before anything else.

What impedance will four subwoofers give me?

Each chamber has its own terminal cup, so you choose the coil wiring on each driver and then how the two cups are joined. With the cups in parallel, four dual 4 ohm drivers reach 2 ohms with the coils in series or 0.5 ohms with them in parallel; dual 2 ohm drivers reach 1 ohm or 0.25 ohms. Putting each chamber's pair in series, or the two cups in series, lands on 8 and 2 ohms instead, or 4 and 1. Match the final load to the amplifier's minimum stable impedance rather than chasing the lowest figure. Calculate impedance for multiple subwoofers works through any set.

Can I run different subwoofers in one cabinet?

No. Run four of the same model at the same impedance. Each chamber is cut for a matched pair, so an odd driver changes both the volume its chamber is working into and the load on that chamber's cup.

Are there ported quad 10 inch boxes?

Not from us. At four drivers the extra volume a port needs no longer fits in the space that made the high driver count worth doing. Vented builds are single and dual cabinets, on the ported page.

Is a quad 10 better than three twelves?

They move close to the same air. Four tens spread it over more motors with less moving mass on each, which starts and stops faster and shares the heat; Three twelves get there with fewer drivers to buy, mount and wire, and a simpler final impedance. What will physically go in the space usually settles it. The dual subwoofer setup guide covers the trade in detail.
