Short answer: the Polk Audio XT15. It ranks #29 of 87 bookshelf speakers by sound quality at $179; the Fluance Signature HFS ranks #76 and costs $199.99, so there is not much of a tradeoff to weigh.
What the Polk Audio XT15 offers: Very low $179/pair entry price for a Hi-Res Audio Certified 2-way design that’s Dolby Atmos and DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs so it drops into almost any AVR without matching concerns. Directivity spread is reasonably even for the price (directivity_spdi_stddev 3.60). Watch for: Bass rolls off earlier than most of this batch at 77.6Hz (-3dB) / 54.2Hz (-10dB). On-axis deviation is the roughest measured figure here (aad_on_axis 0.449), and listening-window smoothness (0.303) trails the pricier options in this group. Modest 86dB sensitivity wants a reasonably powered amp channel. The 5.25” bi-laminate paper woofer is Polk’s entry-tier driver, not the polypropylene/Turbine cones used in its pricier Signature Elite/Reserve lines.
What the Fluance Signature HFS offers: 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. Watch for: 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.
Buy the Polk Audio XT15. It ranks higher for sound quality than the Fluance Signature HFS and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Fluance Signature HFS. It ranks near the bottom of the 87 bookshelf speakers, so look higher up the list instead.
