While superficially resembling the original Grand Piano, which I reviewed in the May 1998 Stereophile, the Home is larger and trades in the 2-way-with-passive-radiator design for a 21/2-way system. Two 7-inch coated glass-fiber-cone woofers handle the lows. The lower bass driver, tuned with a front-mounted port, rolls off gradually above 200Hz. The other 7-inch driver's response continues up to 3kHz. The advantage of this arrangement is that you gain the bass heft of the larger radiating area of the double drivers operating in tandem, without the beaming and intermodulation (IM) distortion problems that can occur when you try to get a larger, single LF driver to simultaneously produces upper mids and bass. A ferrofluid-cooled, 11/2-inch silk-domed tweeter fitted with a "spider" delivers.
