Image Dynamics IDQ10 V.4 10 Inch Subwoofer
The IDQ Series platform scaled to 10 inches: 250 watts RMS, 14.5mm Xmax, 180 ounce motor, aluminum flat-wound extended voice coil, and field-replaceable cone assembly. More cone area than the IDQ8, sealed from 0.60 cubic feet, ported F3 to 28 Hz.

IDQ8 to IDQ10: More Cone, Same Platform
The Image Dynamics IDQ10 V.4 uses the same platform as the Image Dynamics IDQ8 V.4: 180 ounce Extended Y-35 motor, American-made aluminum flat-wound extended voice coil, BASV former with 38.3mm voice coil height, Parabolic Santoprene surround, Nomex spider, Polycarbonate neck joint, and field-replaceable cone assembly. The 10 inch cone adds 380.13 cm2 of piston area versus 213.82 cm2 on the IDQ8, which moves meaningfully more air at the same excursion and allows the driver to work effectively in larger sealed and ported enclosures where the IDQ8 runs out of cone area.
The power rating scales up with the platform: 250 watts RMS versus 125 watts on the IDQ8. This is not an inflated figure; it reflects what the BASV former, aluminum flat-wound coil, and 180 ounce motor can sustain continuously in a properly sized enclosure.

IDQ10 vs ID10: Different Engineering, Different Use Case
The Image Dynamics ID10 V.4 uses a copper voice coil, a fixed cone assembly, and a 127 ounce motor. The IDQ10 uses an aluminum flat-wound extended voice coil, a field-replaceable cone assembly, and a 180 ounce motor. The IDQ10 is engineered for sound quality competition use and long-term serviceability; the ID10 is engineered for reliable daily use at an accessible price. These are different products with different priorities, not the same driver at different price points.
Field-Replaceable Cone Assembly
The IDQ10's cone assembly is held to the basket by 16 screws and positioned using alignment shims included with the recone kit. Replacement requires removing the 16 screws, lifting the old assembly out, positioning the new one with alignment shims, and reinstalling the screws. No adhesive, no curing time, no professional service required. The motor structure, which is the most resource-intensive component to manufacture, stays in service while only the cone assembly is replaced.
For a 10 inch driver operating at competition levels or sustained high-excursion daily use over multiple years, this serviceability is a real operational advantage. The alternative is a new driver purchase or a professional reconing service. With the IDQ10, neither is required.
Sealed and Ported Options
The IDQ10 supports a wide range of enclosure designs. The sealed range runs from 0.60 cubic feet (Compact, 450W max) to 1.60 cubic feet (Audiophile, 250W max). The ported range covers 1.00 to 1.75 cubic feet with tuning from 40 Hz down to 30 Hz, extending F3 to 28 Hz in the Audiophile alignment. Image Dynamics recommends sealed for optimal sound quality, but the ported specifications are fully published in the IDQ Series V.4 manual for builders who want maximum bass extension.
Fitment at a glance: mounting depth 5.81 inches, cutout 9.625 inches, outside diameter 11.04 inches, driver displacement 0.10 cubic feet. Break-in period of several days to one week is recommended before reaching optimal performance per Image Dynamics' instructions.
D2 or D4
The D2 wires to 1 ohm or 4 ohms; the D4 wires to 2 ohms or 8 ohms. Both share 85 dB sensitivity, 14.5mm Xmax, and 180 oz motor. The Vas values differ (24.3 L D2 vs 21.32 L D4), producing higher Qtc on the D4 at the same sealed volume. Choose based on your amplifier's preferred impedance. The enclosure performance section shows both variants.

Sealed Enclosure Performance: Pre-Calculated Results
Using Image Dynamics' published Thiele-Small parameters and their recommended sealed volumes, here are the predicted Qtc, system resonance (Fc), and F3 rolloff. Volumes are net internal per the IDQ Series manual. Calculated using the same formulas as the Audio Intensity Sealed Box Calculator.
The IDQ10 runs high Qtc across the sealed range, producing punchy, impactful bass with a strong midbass lift. This is consistent with the IDQ Series design philosophy: dynamic impact and presence in compact enclosures rather than flat Butterworth accuracy. The F3 values land in the 41-48 Hz range sealed, with ported alignments extending to 28 Hz in the Audiophile configuration. The D4 runs higher Qtc than D2 at the same volume due to its smaller Vas.

Power handling and ported options: Sealed enclosure power handling decreases as volume increases: 450W at 0.60 cu ft, 350W at 1.10 cu ft, 250W at 1.60 cu ft. The IDQ10 ported alignments bring F3 down to 28 Hz in the Audiophile 1.75 cu ft configuration tuned to 30 Hz. For the full port dimensions of each ported alignment, refer to the IDQ Series V.4 manual. Run your own numbers in the Sealed Box Calculator.
