#37 Polk Audio XT30: $139.00 each Amazon eBay
Pros: One of the least expensive centers here at $139, with a 1” Terylene dome tweeter between two 5.25” woofers and 89dB sensitivity. Erin’s Audio Corner measured a flat on-axis response (0.26 average deviation) and deeper bass than the slimmer XT35, reaching 77.6Hz (-3dB) and about 51Hz (-10dB). Measured bass extension of 77.6Hz (-3dB).
Cons: The listening window spans 3.0dB from 300Hz to 5kHz and the predicted in-room response is not very smooth (0.51), so it sounds less even off axis and in reflective rooms. The preference score without a subwoofer is 3.89.
How it compares: Just above it: Arendal Sound 1961 Center - $511 more, 2Hz lower bass extension (-3dB). Just below it: Aperion Audio Novus N5C - $210 more, 1Hz lower bass extension (-3dB).
