Infinity Kappa Perfect 12 VQ Subwoofer /w Vented Sub Enclosure Box

Item is used but in great condition

Infinity understands that the difference between good bass and great bass is in the details. Incorporating the latest low-frequency innovations, the Kappa Perfect12 VQ 12" subwoofer delivers unbeatable performance and system-tuning flexibility.

Resonance is a big time enemy of great bass, and Infinity's revolutionary Magnesium Metal Matrix (M3D) is the ultimate cone material — it's 20 times less resonant than aluminum! Housed in its die-cast frame, the M3D cone is an ultra-stiff piston that translates the low-frequency signal from your amplifier with frightening accuracy. The butylene rubber one-piece surround/gasket exerts tight control over cone excursion so you'll hear smooth bass even when you're really cranking it!

The Kappa Perfect VQ subwoofer offers the unique Variable Q feature, which allows you to optimize the speaker for use with a variety of enclosures — sealed, ported, or bandpass (even free-air applications). The sub is shipped with two metal polepiece inserts, which can be plugged into the motor assembly to vary the stiffness of the suspension:

This patent pending approach also allows you to change the character of your bass for different applications. Imagine — you could tune your subs for sound quality during the week, then retune for an SPL competition on the weekend! Leave it to Infinity to take bass to a whole new place.
