The two coils share the frame, cutout and depth but not the motor figures, so this page prints an alignment for each.

The IDQ12 V4 is a high-Qts driver, 0.68 on the dual 2 ohm coil and 0.74 on the dual 4 ohm, which is the Image Dynamics house character rather than a quirk of this box: a maximally flat sealed alignment would take about 21 cubic feet for the D2, and with Qts above 0.707 the D4 cannot reach it in any sealed volume. In this cabinet the D2 lands at Qtc 1.048 with system resonance at 52.4 Hz and half power at 40.4 Hz, the D4 at Qtc 1.130, 53.5 Hz and 40.1 Hz. Both carry a 1.5 to 2.0 dB rise centred near 70 Hz: a punchy sealed alignment, and this page shows that curve rather than a flat one.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eTwo Fully Separate Chambers\u003c\/h2\u003e\n\u003cp\u003eA bonded full-height 3\/4 inch MDF divider splits the cabinet into two sealed chambers of 1.25 cubic feet net each.

The rear panel rakes 20 degrees, so the cavity deepens from 11.28 in at the top to 17.10 in at the base, and the 5.77 in motor clears it with 5.01 in to spare.

With the dual 2 ohm version, each driver in series (4 ohms) and the pair in parallel gives 2 ohms, and each driver in series with the pair in series gives 8 ohms. Paralleling everything drops to 0.5 ohm, which almost no amplifier will run. With the dual 4 ohm version, each driver in parallel (2 ohms) and the pair in parallel gives 1 ohm, which needs an amplifier rated 1 ohm stable; each driver in parallel with the pair in series, or each in series with the pair in parallel, gives 4 ohms, the safe load on any amplifier. Confirm the final load against your amplifier's minimum stable impedance before powering the system.\u003c\/p\u003e\n\u003cp\u003ePower handling is 375 watts RMS per driver, 750 across the pair.
