Three Drivers, One Cabinet

Triple 10 Inch Subwoofer Boxes

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.

Why Three Drivers

Cone area is the point

The reason to run three drivers instead of two is total cone area in a fixed amount of width. Three tens give you about the same cone area as two twelves, and they do it with smaller moving masses, which start and stop faster than one large cone covering the same area.

A chamber each, not a shared box

Two bonded full-height 3/4 inch MDF dividers split the cabinet into three sealed chambers, one driver each, every one lined with its own polyfill. Drivers sharing a chamber work against each other's compression, and with three of them that interaction compounds. Separate chambers remove it, which is why the alignment printed on the listing is the alignment in each chamber rather than an average across the box.

Three terminal cups, one per chamber

Each chamber gets its own cup, pre-wired in 12 gauge OFC, and all three sit on the rear panel because the centre chamber has no side wall to take one. That is worth knowing before you buy. All three drivers should be the same model at the same impedance, and because the cups land separately you decide two things, not one: how each driver's own coils are wired, and how the three cups are joined to the amplifier. The numbers are below.

Built as a wedge because that is where the width is

The rear panel sits flat against the cab wall or trunk bulkhead and the baffle rakes back to follow the lean of the seat. That is the one place in most vehicles with enough uninterrupted width for three drivers, which is why nearly every cabinet on this page is cut that way.

How to Choose a Triple 10 Inch Box

Start from the driver and buy a matched set

Most of these cabinets are cut to one named driver. Match the model and the coil on the listing, and run three of the same driver at the same impedance. Every chamber is identical and cut to one driver's parameters, so a different driver in one of them gets neither the volume it wants nor the same share of the power.

Work out the final impedance before you buy the amplifier

There are two decisions, not one: how each driver's coils are wired, and how the cups are joined. With the cups in parallel, which is what nearly every install wants, three dual 4 ohm drivers land on 2.67 ohms with each driver's coils in series, or 0.67 ohms with them in parallel. Dual 2 ohm drivers land on 1.33 ohms or 0.33 ohms the same way. 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. What a three driver count cannot give you, in any of those arrangements, is the familiar 1 or 2 ohms. That is the one real catch here: 2.67 ohms wants an amplifier stable at 2, and 1.33 ohms wants one stable at 1. Check the rating before you commit to the box. Calculate impedance for multiple subwoofers does the arithmetic for any set, and what 1 ohm stable means explains why the lowest reachable figure is not always the one to wire for.

Read the per-chamber volume, not the total

The total net volume tells you how big the cabinet is. The per-chamber figure tells you what each driver is working into, and that is the number that decides how the box sounds. Both are on every listing.

Sealed is the whole page

Every triple and quad cabinet we cut is sealed. At three drivers the port volume a vented box needs stops fitting in the space that made the high driver count attractive in the first place. If ported is what you want, it is a two driver or single driver build: the ported page has every vented cabinet.

Or step down a count

The dual 10 inch page and the single 10 inch page cover the same drivers in narrower cabinets.

Will a Triple 10 Fit?

Measure the width first, every time

These 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, not depth or height. Measure the narrowest point of the opening, at seat-back height rather than along the floor, then work down the page from the platform that fits.

Behind a truck seat

The wedges are cut for the space between the seat backs and the rear wall of a cab. How to measure for a wedge box behind a truck seat walks through the three measurements that matter, and which box fits your cab covers the common cabs by name.

On a cargo floor

The down fire cabinets stand on feet with the cones facing the floor, which is the shape for an SUV or a hatch where height is shorter than width. Every down fire cabinet we cut is on the down fire page.

If the width is not there

Two drivers in the same size need less of it. The dual 10 inch page has the same build standards in a narrower cabinet.

Triple 10 Inch Subwoofer Box Questions

Do the three drivers share one chamber?

No. Two bonded full-height dividers split the cabinet into three sealed chambers, so each driver gets its own 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.
