Performance Optimized Dual Sealed 12" Enclosure | Image Dynamics IDQ 12

Proline X Performance Optimized Series Dual Sealed 12" Enclosure | Image Dynamics IDQ12 V4 Two IDQ12 V4 subwoofers. One precision airspace. This driver-specific sealed enclosure is CNC-cut around the IDQ12's published parameters, so a pair of the most musical 12s in car audio gets exactly the box they were engineered for. Driver-Specific CNC-Cut in Tennessee Pre-Wired 1-Year Warranty Engineered Around the IDQ12 V4 The Image Dynamics IDQ12 V4 is a sealed-box subwoofer by design, with an EBP of 40 that tells you exactly where it belongs. This enclosure gives a pair of them the airspace Image Dynamics' parameters call for: approximately 2.8 cubic feet of net internal volume in a shared common chamber, roughly 1.4 cubic feet per driver after displacement. That sits in the extended range of the IDQ12's sealed window, trading a touch of box punch for deeper extension while preserving the transient accuracy that wins sound quality lanes. The baffle is cut for the IDQ12 V4's 10.87 inch cutout on both positions, and the 15 inch depth swallows the driver's 5.91 inch mounting depth with room to breathe. Polyfill comes pre-installed, so the enclosure performs as modeled the day it arrives. 2.8 ft³Net Volume, Common Chamber 30x15x15External Inches (WxHxD) 1000WSystem RMS (2 x 500W) Performance Optimized Construction Every Performance Optimized enclosure is CNC-cut from Langboard Elite MDF on our ShopSabre routers in Tullahoma, Tennessee, with precision V-groove and dado joinery for panel alignment and long-term sealed integrity. The baffle carries 8/32 threaded inserts matched to the IDQ12 V4's published mounting pattern, with stainless steel machine screws included, so the drivers bolt down with real hardware instead of wood screws. Connections run through the Proline X ABS and carbon fiber composite terminal cup with stainless hardware and copper ring terminals, pre-wired with 12-gauge OFC to both driver positions. Drop the subs in, land two wires at the cup, and the install is done. This is the same driver-specific approach as our Professional Series: airspace, cutouts, and hardware locked to one driver, the Image Dynamics IDQ12 V4, rather than averaged across a class of 12s. Finish It Your Way The enclosure comes wrapped in Dark Gray Trunkliner as standard, with Plush Black carpet available as an upgrade. The front baffle accepts a colored acrylic insert in Black, Blue, Red, or White to match the build, or can be ordered without the insert for a clean, blacked-out face at a reduced price. Order the box on its own if you already have your drivers, or bundle it with a matched pair of IDQ12 V4 subwoofers in Dual 2-ohm or Dual 4-ohm, and we ship everything together. A pair of Dual 2-ohm drivers wires to a 2-ohm final load; a pair of Dual 4-ohm drivers wires to 1 ohm or 4 ohms. Airspace Driver-Matched Volume Approximately 1.4 cubic feet per driver in a common chamber, set against the IDQ12 V4's published sealed parameters. Joinery V-Groove + Dado Construction CNC-cut Langboard Elite MDF with precision joinery for rigid panels and an airtight sealed cabinet that stays that way. Hardware 8/32 Threaded Inserts Matched to the IDQ12 V4 mounting pattern with stainless machine screws included. Real fasteners, repeatable torque. Wiring Pre-Wired Terminal Cup Proline X ABS and carbon fiber composite cup with stainless hardware and copper ring terminals, pre-wired in 12-gauge OFC to both positions. Style Acrylic Insert Options Black, Blue, Red, or White front acrylic to match the build, or skip the insert for a blacked-out baffle. Bundles Box Only or Loaded Order the enclosure alone or bundled with a matched pair of IDQ12 V4 drivers in Dual 2-ohm or Dual 4-ohm. The Box Two IDQ12s Deserve Precision airspace, real hardware, and pre-wired connections, built around one driver and cut on CNC in Tennessee. Pair it with 1000 clean watts and let a dual IDQ12 V4 sealed stage do what it was engineered to do.
