From the shop floor

Installer's take

0.65 cubic feet per chamber, Qtc 0.819, F3 39.0 Hz, the same airspace as the EVO 2410 wedge pair.

Measure the installed height, not the cabinet height: 9.24 tall on its own, 10.99 with the standoffs on the 30 by 15 footprint.

Floor slot is 0.89 times the cone area at the 1.75 standoff, a little under the 1.0 I like; taller feet fix it if the floor allows.

The EVO's figures are not from an Audiomobile sheet; the set used is the one that agrees with the driver's 207 gram moving mass.

No published bolt circle, so the inserts ship in the kit: mark from the driver, drill, press. Sealed, so leave the polyfill as it is and run 350 to 500 watts per driver.

Questions

Does this fit the Audiomobile EVO 2410, and will any other 10 inch fit?

The EVO 2410, yes, in the S4 or D4 version. The baffle is cut to 9.2 in, the same cutout as Audiomobile's GT2 10, under the 10.65 in frame. The 3.90 inch motor clears the cabinet with 4.59 inch to spare. Run a matched pair so the chambers match.

Any other 10, no. The airspace is engineered around the EVO 2410's own Qts and Vas, and a different woofer that happened to drop into the hole would not see the alignment printed on this page.

Why 0.65 cubic feet per chamber, and what alignment does it target?

0.65 cubic feet net per chamber: the EVO 2410 reads Qtc 0.819 with resonance at 44.2 Hz and half power at 39.0 Hz. That is a touch above maximally flat: firm and punchy with a small lift near resonance.

Cabinet gain in a vehicle lifts the bottom end further, so in the car this reads deeper than the anechoic figures.

What amplifier power should I run, and how should I wire it?

Audiomobile rates the EVO 2410 at 500 watts RMS per driver, so target 350 to 500 watts RMS per driver at the final load.

Two dual 4 ohm EVO 2410s land on 4 ohms with each driver's coils in series and the pair in parallel, or 1 ohm with everything in parallel; two single 4 ohm drivers give 2 ohms in parallel or 8 in series. Run a matched pair. Confirm your amplifier's minimum stable impedance first.

How tall is this once the standoffs are on?

The cabinet is 9.24 inches tall measured in the down fire position, and that figure excludes the standoffs. The standoffs hold 1.75 inches under the baffle, so plan your space around a finished stack of roughly 10.99 inches.

The footprint is the standard Performance Optimized down fire platform, 30.00 inches wide by 15.00 deep. Height is the only dimension solved to the driver.

Why two separate chambers instead of one shared volume?

Two drivers sharing one sealed volume load each other: each driver's compression stroke becomes the pressure the other works against, which blurs the alignment either would have alone. A bonded full-height 3/4 inch divider gives each driver its own 0.65 cubic feet and its own polyfill.

It also means a failure in one driver does not unload the other, and the alignment on this page is the alignment in each chamber, not an average across a shared box.

What is the expected low-frequency extension?

Anechoic F3 is 39.0 Hz per chamber. Above Qtc 0.707 F3 sits below fc, so the response carries a small lift near resonance before it rolls off.

Those figures exclude cabin gain. In a car the cabin's transfer function adds real output below 50 Hz, so in-vehicle response runs deeper than the numbers above.

Do I need to add polyfill or damping?

No. Polyfill is already installed in both chambers as a light wall lining to control internal reflections, and the quantity is chosen so it does not change the acoustic volume.

Do not add more. Packing a sealed box with fill makes it behave as though it were larger, which walks the alignment away from the 0.65 cubic feet per chamber this cabinet was built to.

Is the driver included, and are the threaded inserts installed?

No driver. This is an enclosure only. You receive the cabinet finished in plush black carpet, one side-mounted pre-wired terminal cup to both positions, the polyfill lining already in place, the standoffs, and a threaded insert kit with stainless machine screws.

The inserts ship loose on purpose: Audiomobile prints no bolt circle for the EVO 2410, so you set the driver in the recess, mark its holes, drill and press the inserts. The pair of Audiomobile EVO 2410 is purchased separately, and the cabinet is cut direct fit to it, not a general purpose 10 inch box.
