Short answer: the Polk Audio XT35. It ranks #14 of 98 center channel speakers by sound quality, rated 4.1/5, at $279; the Aperion Audio Novus N5C ranks #50, rated 3.6/5, and costs $349.30, so there is not much of a tradeoff to weigh.
The Polk Audio XT35 is the more accurate pick. A slim center only 106mm tall, built to sit under a TV, with a 1” Terylene dome tweeter between four 3” woofers. Its measured preference score, a predictor of how neutral it sounds, is 4.43 against 3.55 for the Aperion Audio Novus N5C. 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 Aperion Audio Novus N5C: A sealed three-way center with a 1” silk dome tweeter stacked above a 4” aramid midrange in a vertical array between two 5.25” woofers, which keeps horizontal dispersion wide: Erin’s Audio Corner measured even coverage out to about ±70 degrees, so dialogue stays clear across a wide seating row. Watch for: The listening window spans 4.3dB from 300Hz to 5kHz, among the least even of the centers here, and bass rolls off at 82Hz (-3dB) and about 55Hz (-10dB).
Buy the Polk Audio XT35. It is rated higher for sound quality than the Aperion Audio Novus N5C and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
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.
