Vintage Phase Tech PC800HO // Speakers / Original Box

Perhaps one of the unsung heroes of vintage HiFI, Phase Tech was founded by Bill Hecht, the inventor of the soft dome tweeter, as well as the flat-piston driver. Mr. Hecht's original company, United Speaker Systems, supplied many OEM manufacturers in the late '60s, such as McIntosh and The Fisher. In fact, McIntosh contracted Hecht to design the ML-1C. One of his later designs, the Phase Tech PC 800 is a loudspeaker known for excellent horizontal dispersion, and relatively uniform room response. Take home a piece of HiFi history.

Liner Notes

Phase Tech may not be a household word among audiophiles, but the speakers bearing that brand name are the descendants of a long line of speaker systems designed and manufactured over the past thirty years by William Hecht. Most of Hecht’s products were developed for other manufacturers and were sold under well-known brand names. The new line of speakers manufactured by Phase Technology Corporation and sold under its own Phase Tech brand incorporates several of Hecht’s patented design innovations, among them the widely used soft-dome tweeter.
