Short answer: the XMechanik Mechano23 DIY. It ranks #6 of 179 bookshelf speakers by sound quality (rated 4.4/5) at $200 and is still sold new; the ELAC BS41 ranks #70 (rated 3.5/5) and is discontinued, so it is only an option used.
The XMechanik Mechano23 DIY is the more accurate pick. A DIY bookshelf design with exceptionally accurate sound that rivals far pricier speakers for a modest parts cost. Its measured preference score, a predictor of how neutral it sounds, is 5.42 against 4.29 for the ELAC BS41. The catch: This is a true DIY project.
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 XMechanik Mechano23 DIY. Watch for: The sealed 4-inch woofer limits output and deep bass, so it suits small rooms or pairing with a subwoofer.
Buy the XMechanik Mechano23 DIY. It is rated higher for sound quality and still sold new, while the ELAC BS41 is discontinued.
