Every layer is cut to the A10's published sealed target, with the baffle bored to the A10's 9.06 in cutout with 8/32 threaded inserts set on the back face, and clearance cut for its 3.77 in mounting depth. The A10 carries a published Fs of 27 Hz, Qts of 0.511 and Vas of 40.41 litres, and an EBP of 49, which puts it in sealed enclosure territory. We ran the alignment math on that data and built the box to land where it belongs. Net Volume, Not Gross We build this cabinet at 0.60 cubic feet net, against a published recommendation of 0.85 cu ft gross. The volume quoted is true net internal airspace, measured after the walls, bracing and driver displacement are accounted for. True net, not marketing net. Internal volume is calculated by summing each CNC cut layer's opening, not estimated from external dimensions minus wall thickness. Proline X Micro Series Construction This enclosure is stack fabricated on our ShopSabre routers from Langboard Elite 3/4 inch MDF, a dense 48.5 lb/ft³ board with a 200 psi internal bond and 410,000 psi MOE. Every layer is a precision cut ring and the stacked layers do the joining themselves, so there is no butt joint or dado to flex or leak. Dowel reinforcement runs between layers as tension hardware only. Threaded Inserts, Not Wood Screws 8/32 threaded inserts are set on the backside of the baffle so the driver mounts on machine screws. Pull it a dozen times and the threads are still there. Pre-Wired Terminal Cup Proline X ABS and carbon fiber composite cup with stainless hardware and copper ring terminals, pre-wired internally with 12 gauge OFC. No CCA anywhere in the build. Damped and Finished Polyfill is pre-installed to smooth the in box response, and the shell is wrapped in plush black carpet. Built in Tullahoma, Tennessee. Enclosure Only or Loaded Order the enclosure bare and mount your own A10, or order it loaded and we mount the driver, dress the wiring and ship it ready to bolt in. Sealed Enclosure Performance: Pre-Calculated Using the published Thiele Small parameters for the Arc Audio A10, here is the predicted Qtc, system resonance (Fc) and F3 rolloff for this enclosure. Calculated with the same formulas as the Audio Intensity Sealed Box Calculator.

The D4 A10 carries Qts 0.506 and Vas 41.82 litres, which in this same 0.60 cubic foot volume lands at Qtc 0.941, Fc 50.2 Hz and F3 40.6 Hz. Close enough that either coil suits the box.

This enclosure ships free to the lower 48 with a 2 year limited warranty, built one at a time in Tullahoma, Tennessee.
