#65 Phase Technology PC 3.1: $600 each Discontinued eBay
Newer model: the Phase Technology PC3.5, ranked higher, estimated 3/5.
Pros: A three-way LCR speaker with a 1” soft dome tweeter and 1.5” soft dome midrange on a baffle that rotates for vertical or horizontal use, between two 6.5” woofers. Audio Science Review measured deep bass for a center, 60.1Hz (-3dB) and about 36Hz (-10dB). Measured bass extension of 60.1Hz (-3dB).
Cons: The listening window spans 3.9dB from 300Hz to 5kHz, horizontal coverage is narrow (about ±20 degrees) and the predicted in-room response is not smooth (0.29), for a preference score of 2.95 without a subwoofer. Discontinued; Phase Technology now sells the PC3.5.
