Exacting standards — precise engineering where it counts
The DXi 124 12" sub features a stiff polypropylene cone and sturdy large roll butyl rubber surround, so you can ride the bass wave for years to come. Engineers at Polk analyze drivers in motion to ensure that cone movement is even and precise, so you'll get impressive thump with minimal distortion. Polk also uses laser imaging to craft woofer cones that are perfectly balanced to resist distortion-causing resonances.

Pair this sub with the right amp and wiring, then strap yourself in for a serious low-frequency ride.

Just installed two 12" Dxi 4ohm SVC in ported enclosures in my son's 2001 Yukon, wired in parallel at 2 ohms. Great build quality, sound quality, and they look bad arse! Oh, my son says "they hit hard". Just hope the Yukon hold together. Great customer service as well.

Enclosure Compatibility


Poly Cone: The DXi series subs use a durable polymer composite cone. The cone is both lightweight and rigid, and will withstand the harsh automobile environment.

Butyl Rubber Surround: The butyl rubber surround is resistant to extremes in temperature, humidity, and exposure to sunlight for excellent long term reliability.

Dynamic Balance Driver Technology: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Klippel Optimized: For a driver to reproduce complex sounds accurately, the cone must move exactly the same distance and manner in both directions. The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Polk optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

Break-In Period: Subwoofers will achieve optimal performance once they are thoroughly broken-in. To break in a new DXi sub play music through it for 20 to 30 hours at moderate levels.

Enclosure Compatibility

Sealed Box Volume: Polk recommends mounting this woofer in a sealed enclosure with an internal volume of 0.88 cubic feet.

Ported Box Volume: Polk recommends a ported enclosure with an internal volume of 1.5 cubic feet using a 4" diameter x 10" long port.

Bandpass Box Volume: Polk recommends a bandpass enclosure with a 1.0 cubic foot sealed rear chamber and a 1.15 cubic foot ported front chamber with 4" diameter x 12" long port.
