The IDMAX12 V.4 is Image Dynamics' 12 inch with a 3 inch dual voice coil, 500 watts RMS, 19 mm of one-way travel on 547 square centimeters of cone, 8.07 inches of mounting depth and the bolt-on field-replaceable basket the IDMAX line is known for.\u003c\/p\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003eImage Dynamics' published Universal sealed airspace for the IDMAX12 V.4 is 1.25 cubic feet, and that is what this cabinet was solved to. At 41 inches wide the 8.07 inch motor sets the shallowest depth the cabinet can have, and at that depth each chamber holds 1.32 cubic feet net, slightly more. On this driver more air is the right direction: it brings Qtc down from 1.097 to 1.077 on the D2. One cabinet serves both coils: the D2 reads Qtc 1.077 with half power at 33.9 Hz, and the D4 reads Qtc 1.299 at 32.0 Hz.\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 1.32 cubic feet net each, so every driver sees exactly the airspace printed on this page.

Reaching Qtc 0.707 on the D2 would take about 9.8 cubic feet per driver. What the higher Q buys is a rise around 44 Hz and half power at 32.0 to 33.9 Hz anechoic, before any cabin gain.

A pair of D2 drivers lands on 2 ohms with each woofer's coils in series and the two woofers in parallel, or 8 ohms all in series; all four coils in parallel is 0.5 ohm, which almost nothing is stable into. A pair of D4 drivers lands on 4 ohms with each woofer's coils in series and the woofers in parallel, or 1 ohm with everything in parallel. Use 1 ohm only if your amplifier is rated 1 ohm stable. Run a matched pair, both D2 or both D4. Confirm the final load against your amplifier's minimum stable impedance before powering the system.\u003c\/p\u003e\n\u003cp\u003ePower handling is 500 watts RMS per driver, 1000 across the pair.
