The IDQ is the middle tier of the Image Dynamics subwoofer line, the balance point between sound quality and output. It runs a mica-reinforced polypropylene cone, a parabolic Santoprene surround and a Nomex spider, tuned for tonal accuracy rather than maximum SPL. It is the driver for a build that wants the Image Dynamics sound without the flagship price of the IDMAX.
Like the flagship IDMAX, the IDQ uses a field-replaceable cone, so it can be serviced and re-coned rather than replaced. What separates it from the IDMAX is a poly/mica cone in place of glass-fiber, a lower excursion, and a shallower mount, 4.95 to 5.91 inches deep across the line, which is what makes it fit installs the IDMAX cannot. Every IDQ is available dual 2-ohm or dual 4-ohm.
Every IDQ V4 we stock, with power and excursion verified against the manufacturer. Power is RMS with the peak alongside; Xmax is the one-way linear figure. All three run a 2-inch voice coil at 14.5mm of excursion.
| Model | Size | Voice Coil | Power (RMS / Peak) | Xmax (one-way) | Price |
|---|---|---|---|---|---|
| IDQ8 V4 | 8 inch | Dual 2Ξ© / 4Ξ© | 125W / 250W | 14.5mm | $193.99 |
| IDQ10 V4 | 10 inch | Dual 2Ξ© / 4Ξ© | 250W / 500W | 14.5mm | $238.99 |
| IDQ12 V4 | 12 inch | Dual 2Ξ© / 4Ξ© | 375W / 750W | 14.5mm | $280.99 |
Power steps with size: 125W RMS on the 8, 250W on the 10, 375W on the 12, all at a shared 14.5mm of one-way excursion. Mounting depth runs 4.95 inches on the 8, 5.81 on the 10, and 5.91 on the 12, shallow enough for installs where an IDMAX will not fit. Every model publishes its full Thiele-Small parameters on its product page.
Both are field-replaceable sound-quality drivers, so both can be re-coned rather than replaced. The IDMAX flagship uses a glass-fiber cone and higher excursion; the IDQ is the value SQ choice, the same tonal brief in a poly/mica cone at a lower price and a shallower mount. If the build is judged on accuracy and the budget is set, the IDQ is the one. See the flagship in IDMAX series, the entry line in ID series, and everything in Image Dynamics subwoofers.
The IDQ earns a matched chain. The amplification is in Image Dynamics amplifiers and monoblock amplifiers, the enclosure work in subwoofer enclosures, and the tuning belongs to a DSP on an SQ build. The full Image Dynamics range is in the Image Dynamics collection.
Sound quality at a mid-tier price. The IDQ runs a mica-reinforced polypropylene cone, a parabolic Santoprene surround and a Nomex spider, tuned for tonal accuracy and balanced output rather than maximum SPL. It is the driver for a build that wants the Image Dynamics sound character without the flagship price of the IDMAX.
Both use a field-replaceable cone assembly, so both can be re-coned rather than replaced. The IDMAX flagship uses a glass-fiber and pulp cone with higher excursion; the IDQ uses a poly/mica cone at a lower price and a shallower mount. Both are Santoprene-surround sound-quality drivers; the IDMAX is the reference, the IDQ is the value SQ choice.
The IDQ8 is 125W RMS (250W peak), the IDQ10 is 250W RMS (500W peak), and the IDQ12 is 375W RMS (750W peak). All three are available dual 2-ohm or dual 4-ohm. Match your amplifier's RMS output at your wired impedance to the driver's RMS rating, not the peak figure.
A matched sealed or ported enclosure built to the driver's published Thiele-Small parameters. Audio Intensity builds a Proline X Performance Optimized enclosure spec-matched to the IDQ 10, in single and dual configurations, which extracts measurably more output than a universal-fit box. Tell us the size and space and we will size the enclosure to the driver.
A monoblock matched to the driver's RMS at your wired impedance. The Image Dynamics SQ600.1D pairs cleanly with a single IDQ. Wire the dual coils to the load where your amp makes its rated clean power, and aim for the amp's RMS at 100% to 150% of the driver's RMS.
Yes. Audio Intensity is an authorized Image Dynamics dealer. Every IDQ in this collection is brand new and carries the full manufacturer warranty. Demo units are labeled as such on the product page.
Spec-Matched Enclosures
Every Proline X enclosure is CNC-cut to the Thiele-Small parameters of a specific driver. Internal volume, port tuning, baffle thickness, and bracing calculated from measured driver data. Built and shipped from Tullahoma, TN.
