This enclosure holds 0.76 cu ft net per chamber. In it the Kicker SoloX L7X 10 (49L7X101) runs a system Qtc of 0.54–0.56 with half power at 62.9–68.3 Hz, and the cone reaches its 31.25 mm travel limit at 3585 W, above the driver’s 2000 W thermal rating, so heat stops you before travel does. Run a subsonic filter at 25 Hz and that becomes 5814 W — +2229 W, or 62 percent more power for the same 31.25 mm of travel.

01Is it a sealed driver?

Efficiency bandwidth product places the motor before anything else is decided.

EBP = Fs ÷ Qes = 79.2–86.0
SEALED 0–50 TRANSITION 50–100 PORTED 100–150 0 50 100 150 D1 86.0 D2 79.2
D1 · EBP 86.0D2 · EBP 79.2
At 79.2–86.0 the SoloX L7X 10 (49L7X101) sits in the transition band, not the sealed band. That is not a mismatch: a transition motor works in either alignment, and sealed buys a smaller box and a gentler roll-off at the cost of some low-end output. Stage 02 shows what this airspace actually does with it.

02What the box does to it

0.76 cu ft against a 6.8 L Vas.

α = Vas ÷ Vb = 0.32  ·  Fc = Fs√(α+1) = 47–49 Hz  ·  Qtc = 0.54–0.56
20 30 50 70 100 150 200 +6 +0 -6 -12 -18 -24 FREQUENCY · Hz LEVEL · dB −3 dB
D1 · Qtc 0.54, Fc 49 Hz, F3 68.3 HzD2 · Qtc 0.56, Fc 47 Hz, F3 62.9 Hz
The box lifts resonance from 39.6–43.1 Hz free-air to 47–49 Hz and half power lands at 62.9–68.3 Hz, anechoic, before any cabin gain. This enclosure ships without a driver, so both coil variants the maker offers are plotted. They do not load the same box the same way.

03The watts that reach Xmax (in this enclosure)

Travel scales with the square root of power, so there is one wattage that puts the cone exactly on 31.25 mm — and a bigger one once a subsonic filter stops it wasting travel below the passband.

PXmax = 3585–4370 W unfiltered  →  5814–6967 W with a 25 Hz subsonic
20 30 50 70 100 150 200 0 8 16 24 32 FREQUENCY · Hz CONE TRAVEL · mm PAST LINEAR TRAVEL · Xmax 31.25 mm 3585 W reaches Xmax here

Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 31.25 mm. Unfiltered that is 3585 W, reached first at 20 Hz. It sits above the 2000 W the driver can take thermally, so the voice coil gives up before the suspension does. The dashed traces are the same driver behind a subsonic filter at 25 Hz, 24 dB/oct: stopping the cone wasting travel below the passband lets it take 5814 W before hitting the same 31.25 mm. That is 62 percent more amplifier for the price of one filter setting.

Installer's take

This is the sound-quality flagship of the wedge line with the volume knob unlocked. Each Solo X 10 gets its own 0.76 cubic foot chamber at the same maximally damped mid-0.5s Qtc as the single 10, so you keep the gated-sample transient control and add 6 dB of capability from the second cone. For a serious SQ truck build with real output demands, this is the box I would spec.

The full-height divider is doing two jobs. It isolates each driver in its own air so neither modulates the other's alignment, and it stiffens a 27.75 inch wide cabinet right at its widest span. Two drivers sharing one chamber would trade the precision this alignment exists for; that is not a compromise we build.

Matched coils, identical wiring, one cup. A pair of dual 1-ohm 10s lands at 1 ohm or 4 ohms in the common configurations; a pair of dual 2-ohm at 2 ohms or 0.5. Map that against your amplifier before choosing drivers, and remember the pair wants real power: 2000-4000 clean watts across the two per Kicker's per-driver recommendation.

In the cab, the low-Q anechoic rolloff and rising cabin gain cancel almost perfectly, so the pair plays flat and deep in the vehicle while staying bone-dry on transients. Fit: 27.75 wide, 13.5 tall, 16.25 deep at the floor tapering to 11.375. Measure the clear span behind the seat between belt towers before ordering.

Questions

Will my Kicker Solo X 10s fit this enclosure?

Yes. Each baffle opening is CNC-cut to Kicker's published 9-5/16 inch cutout for the Solo X L7X 10, and each chamber clears the required 9-7/16 inch mounting depth with margin, including breathing room for the vented motors. Both coil versions fit; just use a matched pair.

Why two separate chambers instead of one shared volume?

Because this box exists for control, and shared air destroys control. When two drivers see one volume, each cone's compression stroke changes the pressure the other operates against, smearing the transient precision a maximally damped alignment is built to deliver. The full-height 3/4 inch divider gives each Solo X 10 its own 0.76 cubic feet, keeps both chambers identical, and braces the cabinet's widest span at the same time.

Do both subwoofers need to be the same coil version?

Yes. Run two dual 1-ohm drivers or two dual 2-ohm drivers, never one of each. Identical drivers wired identically off the shared cup split power evenly and move in lockstep; mixed coils create unequal branch impedances and unbalance the pair. A dual 1-ohm pair commonly wires to 1 or 4 ohms, a dual 2-ohm pair to 0.5 or 2 ohms; pick whichever lands on your amplifier's rated load.

How much power should I run to a pair of Solo X 10s?

Kicker recommends 1000-2000 watts RMS per Solo X 10, so plan 2000-4000 watts RMS of clean power across the pair at your wired impedance. The maximally damped chambers keep both cones loaded hard through the passband, which is what makes the top of that range genuinely usable. Set gains with a scope or DMM and one strong monoblock into the shared cup is all the system needs.

How does the dual 10 compare to the single 15 wedge?

They are different answers to different questions. The pair of 10s gives you nearly 12-inch-class cone area in a 13.5 inch tall cabinet with the tightest damping in the line; the 15 stands 18.25 inches, runs the classic Butterworth 0.707, and reaches deeper anechoically with its 45 Hz F3. If your priority is transient precision and a lower profile, take the dual 10s. If it is extension and effortless low-end weight from one big cone, take the 15. Output capability between them is closer than the driver sizes suggest.

Will this wedge fit behind the seat of my truck?

You need 27.75 inches of width, 13.5 inches of height, and 16.25 inches of depth at the floor; the top needs only 11.375 inches thanks to the 20 degree baffle rake, and the vertical rear panel sits flat against the cab wall. Height and depth are friendly for a dual 10; width is the dimension to verify, so measure the clear span behind your seat between belt towers and trim before ordering.

Are the subwoofers included with this enclosure?

No, this listing is the enclosure only. It is built for a matched pair of Kicker Solo X L7X 10s, which you install using the pressed 8/32 threaded inserts and the two sets of included stainless mounting hardware.
