Short answer: the Polk Audio Reserve R350. It ranks #40 of 98 center channel speakers by sound quality, rated 3.7/5, at $519. The Polk Audio Signature Elite ES35 ranks #80, rated 3.4/5, at $319, $200 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Polk Audio Reserve R350 is the better-sounding choice. A slim sealed center, 141mm tall and 188mm deep, with a 1” Pinnacle ring radiator tweeter and four 4” Turbine cone woofers, designed to sit under a TV or mount on a wall. Watch for: Bass rolls off at 85Hz (-3dB) and about 49Hz (-10dB), so a subwoofer is needed.
Why pick the Polk Audio Signature Elite ES35: Ultra-slim 4.1-inch height profile fits under wall-mounted TVs without blocking screen view. The tradeoff: Small 3-inch drivers roll off below 70Hz, requiring pairing with a subwoofer.
Buy the Polk Audio Reserve R350. It is rated higher for sound quality, and saving $200 with the Polk Audio Signature Elite ES35 does not make up for the sound-quality gap.

Pros: A slim sealed center, 141mm tall and 188mm deep, with a 1” Pinnacle ring radiator tweeter and four 4” Turbine cone woofers, designed to sit under a TV or mount on a wall. Audio Science Review measured a fairly flat on-axis response (0.31 average deviation), and the score rises to 6.72 with an ideal subwoofer. Measured bass extension of 85.0Hz (-3dB).
Cons: Bass rolls off at 85Hz (-3dB) and about 49Hz (-10dB), so a subwoofer is needed. The listening window spans 3.0dB from 300Hz to 5kHz, and the preference score without a subwoofer is a middling 3.97.
