DXi112 Features:

Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.

Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

Internally braced heavy duty 3/4-inch MDF, the same low-resonance material used in the world’s finest speaker enclosures.

Heavy-duty baffle design not only looks cool, it also protects the drivers.

Slot-loaded port reduces air turbulence at the port mouth for higher bass output and greatly reduced noise and distortion than conventional ports.

Tri-laminate sandwich cabinet construction creates tight, powerful bass.

Paintable baffle is clad in automotive grade ABS trim for rigidity and impact resistance.

Elastomeric damping material isolates ABS trim from baffle and acts as sealing gasket.

2 ohm load is optimum for today’s class D subwoofer amplifiers.

Polypropylene cones are stiff for quick, tight, punchy bass, and durable to stand up to the demands of hot automotive environments.

Santoprene surrounds are impervious to temperature extremes, humidity and exposure to sunlight for superior long-term reliability.

Fire retardant flat NOMEX® spiders permit extended linear motion while providing highly reliable mechanical and thermal stability.

Former and pole piece vent the 4-layer high temperature voice coil former for exceptional power handling and reliability.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
