Polk Audio recently unveiled their new line of GNX Subwoofers, i chose to post in particular the GNX12DVC which definatly looks the buisness for either quality or a nice loud thrasing:
Picture of the GNX12DVC
Get dual 4-Ohm voice coil flexibility from this 12", Dual Voice Coil GNX Subwoofer. Series it for 8-Ohm and Parallel it for 2-Ohm loads. More bass for less!
Like all the GNX Subs, it's totally optimized to work great in virtually any type of enclosure from Sealed to Vented to Band-Pass (if you can build it, GNX will rock it!)... Without emptying your wallet.
GNX Subs are available in two sizes, 10 inch and 12 inch, and three flavors of impedance, including Dual Voice Coil models (which can be paralleled for 2-Ohm or wired in series for 8-Ohm loads).
*Optimized for high performance in virtually any enclosure type: sealed, vented and bandpass.
*Super strong and durable Poly-Mica Cones for gut-pounding bass.
*Huge, injection molded ABS dust cap further stiffens the cone to supress unwanted resonance. You get incredible low distortion, high impact bass response.
*Extra beefy (beefy!) magnet structure and motor assembly for high output bass with tight control.
*Four-layer vented voice coil runs cool while your music stays hot.
*Vented pole piece for higher efficiency and ultra high power handling.
*Gold-plated three-way wire terminals for secure wire termination (fast-on, solder or screw terminal choices)
*Durable rubber surround for extended life performance.
