Triple 10 Inch Subwoofer Boxes

Triple 10 inch subwoofer boxes, CNC-cut in Tullahoma, Tennessee.

Triple 10 inch subwoofer box built by Proline X in Tullahoma, Tennessee

Three Drivers, One Cabinet

Three tens sits in the middle of this range: about the same cone area as two twelves, and it gets there without asking for the full width of the cab wall that the twelves need.

Every cabinet on this page is sealed and holds three 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 triple 10 inch cabinets, wedge and down fire, 33, 38 or 40 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.

Triple 10 Inch Subwoofer Box Questions

Do the three 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 triple 10 inch box?

They are built on 3 platforms, 33, 38 or 40 inches wide, and every listing prints its full external dimensions. Width is the constraint at this driver count, so measure the narrowest point of the opening first.

What impedance will three subwoofers give me?

Each chamber has its own terminal cup, so you choose the coil wiring on each driver and then how the three cups are joined. With the cups in parallel, three dual 4 ohm drivers reach 2.67 ohms with the coils in series or 0.67 ohms with them in parallel; dual 2 ohm drivers reach 1.33 ohms or 0.33 ohms. Joining the three cups in series instead multiplies where parallel divides, and takes the same drivers to 24 and 6 ohms, or 12 and 3. 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 three of the same model at the same impedance. Each chamber is cut to one driver's parameters, so a different driver in one of them changes both the volume it is working into and the load on its own cup.

Are there ported triple 10 inch boxes?

Not from us. At three 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 triple 10 better than two twelves?

They move close to the same air. Three tens spread it over more motors with less moving mass on each, which starts and stops faster and shares the heat; Two 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.
