Short answer: the Fluance Signature HFS, though neither ranks well in its class. It ranks #79 of 90 bookshelf speakers by sound quality, rated 2.1/5, at $199.99. The Polk T15 ranks #81, rated 1.9/5, at $149, $50.99 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 90 bookshelf speakers, and the Neumi BS5, ranked #22 at $139.99, is a better place to start if sound quality matters.
Buy the Fluance Signature HFS. It is rated higher for sound quality, and the $50.99 saving on the Polk T15 is not enough to make up the difference.

The Two Speakers In Full
Fluance Signature HFS: $199.99 per pair Amazon eBay
Pros: Front-facing port and pre-installed wall-mount brackets make it flexible for bookshelf or surround/height duty. Distortion in the low end is well controlled per the measurements, and the glossy front baffle adds a touch of style well beyond the budget price. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 86dB.
Cons: CEA2034 spinorama shows serious flaws in the midrange: both the direct sound and the directivity are compromised, a combination the reviewer flagged as poor for controlled listening tests. Multiple attempted EQ fixes “could not rescue” the sound, and the reviewer said the result was “close” to the lowest possible rating. Online reviews seeded by the company were positive; the reviewer’s measured and subjective experience was not.

Polk T15: $149.00 per pair Amazon eBay
Pros: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Measured bass extension of 88.6Hz (-3dB), with a measured sensitivity of 89dB.
Cons: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”
