Your Ride. Our Outrageous Bass.

Don’t let the DXi108 sub enclosure fool you. This compact 8-inch sub enclosure can pump out some serious bass. That’s because the DXi108 is built to the same fit and finish standards as our bigger DXi112, with the same attention paid to all the details. The easy-to-install DXi108 is smaller for those installs where space is at a premium but the thump still needs to be big. The DXi108 is proof that small space doesn’t have to mean small bass.

DXi108 Features:

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 driver.

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

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

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

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

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

Durable rubber surround is impervious to temperature extremes, humidity and exposure to sunlight for superior long-term reliability.

Fire retardant flat spider affords extended linear motion while providing highly reliable mechanical and thermal stability.

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

State-of-the-art Klippel laser analyzer optimized voice coil alignment, motor and suspension ensures cone travel linearity, resulting in flatter response and lower distortion.

Nickle-plated fast-on connectors offer secure connections.
