Short answer: the Polk Audio XT35. It ranks #14 of 98 center channel speakers by sound quality, rated 4.1/5, at $279; the Polk Audio Signature Elite ES30 ranks #58, rated 3.5/5, and costs $299, which makes this an easy call rather than a real tradeoff.
The Polk Audio XT35 is the better-sounding choice. A slim center only 106mm tall, built to sit under a TV, with a 1” Terylene dome tweeter between four 3” woofers. The catch: Small woofers limit bass to 85Hz (-3dB) and about 59Hz (-10dB), so it really needs a subwoofer with a crossover around 100Hz.
Why pick the Polk Audio Signature Elite ES30: The updated version of the Signature S30 with the same two-way layout: a 1” Terylene dome tweeter between two 5.25” polypropylene woofers in a bass reflex cabinet, rated at 89dB and compatible with 4 or 8 ohm amplifier outputs. The tradeoff: 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’s measurements.
Buy the Polk Audio XT35. It is rated higher for sound quality than the Polk Audio Signature Elite ES30 and costs less, which makes it the one to get unless you need something the other one does better.

Polk Audio XT35: $279.00 each Amazon eBay
Pros: A slim center only 106mm tall, built to sit under a TV, with a 1” Terylene dome tweeter between four 3” woofers. Erin’s Audio Corner measured very low on-axis deviation (0.19, among the flattest of any center here) and a listening window within 2.2dB from 300Hz to 5kHz, for a preference score of 4.43 that reaches 7.34 with an ideal subwoofer. That is a remarkable result at $279. Measured bass extension of 85.0Hz (-3dB).
Cons: Small woofers limit bass to 85Hz (-3dB) and about 59Hz (-10dB), so it really needs a subwoofer with a crossover around 100Hz. Its predicted in-room response is less smooth (0.57) than the top centers here, so reflections color the sound more in a lively room.

Polk Audio Signature Elite ES30: $299.00 each Estimated Amazon eBay
Older model: the Polk Audio Signature S30 (ranked higher, rated 3.5/5).
Pros: The updated version of the Signature S30 with the same two-way layout: a 1” Terylene dome tweeter between two 5.25” polypropylene woofers in a bass reflex cabinet, rated at 89dB and compatible with 4 or 8 ohm amplifier outputs.
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’s measurements. Its predecessor measured with an uneven listening window, and this design keeps the same basic two-woofer layout, which limits horizontal coverage.
