Since each module contains its own crossover components, system wiring requires only simple parallel connections from each satellite to its bass section and from each bass module to the amplifier. It is a four-piece system in which two small satellite speakers reproduce the frequencies above approximately 100 Hz and a pair of separate bass modules roughly cover the octave from 120 to 50 Hz. Given Kloss's technical expertise and distinguished record in designing high-quality speakers that could be sold at affordable prices, we were especially interested in hearing and evaluating CSW's initial product, the Ensemble. One of its principals is Henry Kloss, who was a co-founder some thirty-five years ago of Acoustic Research and later went on to found such well-known companies as KLH, Advent, and, most recently, Kloss Video. The cannon balls blasts on the Master and Commander DVD packed more of a wallop than we're used to.Cambridge SoundWorks is a recently established speaker company, but it actually provides a direct link to the earliest days of the high-fidelity industry. That ultralow bass capability is mostly heard on DVDs with lots of special effects-you know, the ones that really shake the room. With the P300HD, we measured smooth bass down to 35Hz in our home theater. The P300HD's extra deep (lowest frequency) bass exceeded every sub we've ever tested for CNET but one: the larger (21.75 inches tall, 15 wide, and 22 inches deep) Outlaw LFM-1. The only other sub we've ever heard that can pull off that trick was B&W's bowling-ball-shaped PV1 sub ($1,500), but the Cambridge sub is more powerful than the B&W which uses just two 8-inch woofers. We also noted that even when we stood right next to the HD P300HD, we couldn't detect it as a source of sound-all of the bass seemed to be coming from the MC600HD speakers! We can pay no higher complement to a subwoofer. The subwoofer won't directly transmit energy through the floor to the room below your home theater (some of the bass will, of course, be audible in that room, but possibly less than that from a conventional sub). So if you place your hand on the P300HD, even when it's pumping out lots of bass, you won't feel it moving-not in the slightest. Actually, the P300HD deploys three speakers on each end of the cabinet the design gambit effectively cancels cabinet vibrations. Instead of relying on a single 10- or 12-inch woofer, the P300HD boasts a total of six 6.5-inch woofers (all powered by the sub's 300-watt amplifier). Controls are limited to a large, illuminated volume control that's conveniently located on the top panel.
There's also an RJ-11 jack, which is for use with Cambridge's P500 and P1000 Sound Consoles. We'd guess almost every buyer will use one of the stereo RCA inputs, but-if your A/V receiver is old enough to not have a subwoofer output-you can hook up the special speaker wires that come with the HD P300HD to the receiver's left and right speaker connections. We evaluated it as part of the 5.1 package, but there's no reason that demanding audio enthusiasts wouldn't want to mix and match this extraordinary subwoofer with other brands' speakers as well. As such, Cambridge bundles the HD P300HD with the HD MC600HD in 2.1, 5.1, 6.1, and 7.1 configurations. The subject of this review, the P300HD powered subwoofer ($1,000), is the ideal mate for the company's speaker ($500 each).

Cambridge SoundWorks' Newton Series HD Loudspeaker line was designed to not only visually complement flat-screen HDTVs, the sound is said to be as high-definition as the picture.
