#31 Klipsch RP-404C II: $399.99 each Amazon eBay
Pros: A shallow sealed center only 164mm deep, easy to wall mount or tuck under a TV, with four 4” Cerametallic woofers around a 1” titanium tweeter in a Tractrix horn and a 94dB sensitivity. Erin’s Audio Corner measured a preference score of 7.17 when paired with an ideal subwoofer. Measured bass extension of 124.5Hz (-3dB).
Cons: Bass rolls off very early, at 124.5Hz (-3dB) and about 77Hz (-10dB), so it needs a subwoofer crossed over higher than the usual 80Hz, and without one its score drops to 3.54. On-axis response is uneven (0.87dB average deviation) and the listening window spans 3.5dB from 300Hz to 5kHz.
How it compares: Just above it: JBL HDI-4500 - $1720 more, 4Hz lower bass extension (-3dB). Just below it: Polk Audio Reserve R350 - $119 more, 7Hz lower bass extension (-3dB).
