Short answer: the Polk Audio XT15. It ranks #29 of 90 bookshelf speakers by sound quality, rated 3.7/5, at $179; the ELAC BS41 ranks #41, rated 3.5/5, and costs $180, so there is little reason to consider the other one.
Why pick the Polk Audio XT15: 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. The catch: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB).
Why pick the ELAC BS41: A small sealed two-way with a 4-inch woofer and a 1-inch tweeter that measures more evenly than its low price suggests. The catch: The sealed 4-inch woofer limits output and deep bass, so it suits small rooms or pairing with a subwoofer.
One note: the ELAC BS41 is discontinued, but it still ranks #41 of 90 bookshelf speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Polk Audio XT15. It is rated higher for sound quality than the ELAC BS41 and costs less, which makes it the one to get unless you need something the other one does better.

Polk Audio XT15: $179.00 per pair Amazon B&H Photo Video Crutchfield eBay
Pros: 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. Off axis sound tracks the on axis response reasonably consistently for the price. Measured bass extension of 77.6Hz (-3dB).
Cons: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB). On-axis response is relatively uneven, with an average deviation of about 0.45dB, and its listening window is less smooth than pricier speakers. 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.

ELAC BS41: $180.00 per pair Discontinued Amazon eBay
Pros: A small sealed two-way with a 4-inch woofer and a 1-inch tweeter that measures more evenly than its low price suggests. Erin’s Audio Corner found the listening window within a 2.5dB span from 300Hz to 5kHz and a predicted in-room response smoothness of 0.60, for a preference score of 4.29 (6.57 with an ideal subwoofer). Bass reaches about 54Hz (-3dB) and 47Hz (-10dB), and the sealed box makes it easy to place near a wall. Measured bass extension of 54.2Hz (-3dB).
Cons: The sealed 4-inch woofer limits output and deep bass, so it suits small rooms or pairing with a subwoofer. Sensitivity is a modest 84.5dB. It is discontinued and mostly found used.
