Center Channel Speakers
Ranked #62 of 71 in Center Channel Speakers - Phase Technology PC3.5: $1,803 each Estimated House of Stereo eBay
Older model: the Phase Technology PC 3.1 (ranked lower, rated 2.9/5).
Pros: The current Premier Collection LCR keeps the PC 3.1’s layout: a 1” soft dome tweeter and 1.5” soft dome midrange on a rotatable baffle between two 6.5” tri-laminate Kevlar/RPF/glass fiber flat-piston woofers, rated down to 36Hz.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured centers; the rating is estimated from its predecessor and lineup siblings. Its measured predecessor had narrow horizontal coverage and an uneven listening window, so the estimate is cautious. Phase Technology’s own site no longer lists it, so stock is limited to remaining dealers.

Center Channel Speakers
Ranked #65 of 71 in Center Channel Speakers - 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.
