Professional Series Ported Dual 15" Enclosure Memphis Audio MOJO1512 · Dual 15" Ported enclosure

Both drivers share one chamber and one port rather than sitting in separate boxes, so the pair works against the whole volume and the port is sized for the pair rather than doubled. The port carries 53.6 square inches of area at 30.0 Hz, and the design power for the velocity and excursion checks is 3600 W for the pair. Passband ripple holds at 1.80 dB across the tuning, with F3 at 36.8 Hz. Tuning is chosen for in-car response rather than an anechoic curve: a vehicle adds roughly 12 dB per octave below about 45 Hz, and this tuning is where that sum comes out flattest across 25 to 60 Hz.

Every driver is tried in the Performance Optimized ported wedge and down-fire before this chassis, and both of those hold one driver. A pair of MOJO1512s sharing one vented chamber needs the Professional envelope, and this box has the width, depth and port to carry both. An under-ported box does not fail quietly. Air speed at the mouth rises with power; past the chuff line the flow turns turbulent and the port is audible on every note. The turbulence also chokes the port, so the box behaves as if it were tuned higher than it is, loses output near tuning, and lets the cone travel further below tuning than the design allows. This chassis is a full-size front-firing box on a 2.25 inch baffle built from three 3/4 inch layers with the woofer flush-mounted in the outer layer, a Memphis Audio logo acrylic, and a port and excursion budget checked at 3600 W. It carries a 2 year warranty, against 1 year on the Performance Optimized lines.

Memphis Audio does not publish the mounting hole locations for the MOJO1512, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with two kits, one per woofer.

Yes, at 24 Hz, 24 dB per octave. Below tuning a vented box stops loading the cone and excursion runs away toward DC. With the filter in place this cabinet puts the Memphis Audio MOJO1512 at 52 percent of its usable travel at 3600 W.

Not one we can show you. We do not build a sealed enclosure for the Memphis Audio MOJO1512, and the sealed volume Memphis prints for it appears word for word on three different Memphis 15 inch sheets, so the Performance Graphs tab carries no ported-versus-sealed chart: the only sealed box left to plot would be this cabinet stuffed and sealed, which nobody would build, and a comparison against it would tell you nothing you could buy. What a vented box gives up is the region below tuning, where the cone unloads and the 24 Hz subsonic filter takes over; around 30.0 Hz the vent carries the load and cone travel drops to its minimum, which no sealed alignment can do.

It is a vertical slot beside the woofer, the full height of the cavity, 3.25 inches wide and 53.6 square inches. It runs 10.50 inches to the back wall and turns once along it for 15.81 inches; the fold costs about 1.5 Hz and the port is cut for it. The channel runs at 23.0 metres per second at 3600 W, 55 percent of its turbulence limit, and the mouth edges carry a 1/2 inch roundover so the air leaves the face at 16.6 metres per second against the 17 metres per second threshold where a slot starts to chuff.

76 lb, 44.00" W x 18.00" H x 17.50" D external. It ships as a UPS parcel; the price includes shipping in the 48 states. Every Professional cabinet is priced the same way, by its size: this one is 8.02 cubic feet outside. Do not add polyfill; it ships dry on purpose.

No. This is an enclosure only, cut for the Memphis Audio MOJO1512 specifically: the 14.050 inch cutout, the 9.650 inch mounting depth allowance and the 3.58 cubic foot alignment all come from Memphis Audio's published parameters. It is one driver with a FLEX impedance jumper: the alignment published here is the 2 ohm setting, and the cabinet passes every gate at 1 ohm too. It is not for the 2025 MJ1512, which uses a 13.81 inch cutout. Bring your own driver.
