Short answer: the Polk Audio XT15. It ranks #51 of 179 bookshelf speakers by sound quality (rated 3.7/5) at $179 and is still sold new; the ELAC BS41 ranks #70 (rated 3.5/5) and is discontinued, so it is only an option used.
Why pick the Polk Audio XT15: Very affordable bookshelf speakers that work with 4 or 8 ohm receivers, an easy fit for stereo or home theater surrounds. The catch: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB).
The ELAC BS41 is the deeper-bass choice. Small sealed budget bookshelf speakers that are easy to place near a wall, a fit for small rooms or setups with a subwoofer. Its bass reaches about 54.2Hz before falling 3dB, against 77.6Hz for the Polk Audio XT15. The tradeoff: The sealed 4-inch woofer limits output and deep bass, so it suits small rooms or pairing with a subwoofer.
Buy the Polk Audio XT15. It is rated higher for sound quality and still sold new, while the ELAC BS41 is discontinued.
