Wireless subwoofer coming from Infinity

If you want to boost low frequency power in your audio/video system by adding a subwoofer, but face a difficult challenge getting the wire from your amp or receiver to the spot where you want to put the subwoofer, Infinity has a solution for you.

Their new PS212W powered subwoofer (due in January 2008) eliminates the need to route wires to the subwoofer through walls or under the floor or above the ceiling, for greater installation flexibility. It received a 2008 Consumer Electronics Show Design and Engineering Award.

The PS212W uses a compact radio transmitter that operates in the 2.4GHz frequency range and offers four selectable channels, a feature that should eliminate interference. (Other wirelesss devices, including LANs and cordless phones, use 2.4GHz.)

The transmitter module connects to an audio source and sends signals to a receiver built into the subwoofer cabinet. The cabinet has a built-in 400-watt amplifier, and a 12-inch woofer featuring proprietary Infinity® Metal Matrix Diaphragm™ (MMD®) driver material, which is manufactured by anodizing both sides of an aluminum core to a controlled thickness. This process is said to "produce a low-mass, highly rigid driver diaphragm that operates with greatly reduced distortion and delivers exceptional articulation and resolution."

(The speaker is not completely wireless -- it needs AC power for its internal amp and radio receiver -- so you will need a nearby outlet.)

The PS212W features variable crossover frequency and level controls, and a phase switch to optimize bass performance. It also includes line-level and LFE inputs, enabling its use as a wired subwoofer if you want. The PS212W can add extended low-frequency capability to any home entertainment system, but has a black-ash finish and black curved grille that matches Infinity Primus® Series speakers. Suggested retail price is $679. CLICK for the Infinity website.
This is a preview, not a review.

INFINITY FOOTNOTE: Back around 1971, Infinity was known for making excellent and expensive speakers, usually costing $1,000 or more. Someone decreed that the company should broaden its market with a new line of speakers priced as low as a hundred bucks, following a similar move by competitor JBL. Infinity engineers viewed this move as heresy, and expressed their displeasure by naming the first low-priced Infinity model, the "POS-1." POS stood for "piece of shit."
