Short answer: the Klipsch Reference R-40M, though neither ranks well in its class. It ranks #164 of 168 bookshelf speakers by sound quality, rated 1.4/5, at $199.99. The Klipsch R-41M ranks #166, rated 1.3/5, at $141.55, $58.44 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 168 bookshelf speakers, so if sound quality matters, consider the Neumi BS5 instead, ranked #38 at $139.99.
Why pick the Klipsch Reference R-40M: The current next-generation 4-inch passive bookshelf speaker replacing the Klipsch R-41M. The tradeoff: Awaiting published full NFS preference scores.
What the Klipsch R-41M does well: Binding posts are unusually nice for the price point, and impedance is well controlled in the bass, easing the load on the amplifier. The catch: CEA2034 spinorama shows a sharp, prominent peak around 1kHz that the reviewer compared to “Pinocchio’s nose,” plus poor directivity that makes the off-axis sound diverge sharply from on-axis.
Buy the Klipsch Reference R-40M. It is rated higher for sound quality, and the $58.44 saving on the Klipsch R-41M is not enough to make up the difference.
About the ratings: the Klipsch Reference R-40M’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 1.2 to 1.6, so this verdict could change once it is measured.

Klipsch R-41M: $141.55 per pair Amazon eBay
Newer model: the Klipsch Reference R-40M, ranked higher, estimated 1.4/5, released 2022. See every Klipsch Reference generation.
Same family: the Klipsch R-51M (larger bookshelf, ranked higher, rated 1.6/5).
Pros: Binding posts are unusually nice for the price point, and impedance is well controlled in the bass, easing the load on the amplifier. The horn-loaded tweeter can play loud without strain. Measured bass extension of 80Hz (-3dB), with a measured sensitivity of 85dB.
Cons: CEA2034 spinorama shows a sharp, prominent peak around 1kHz that the reviewer compared to “Pinocchio’s nose,” plus poor directivity that makes the off-axis sound diverge sharply from on-axis. Sensitivity is only 85dB through most of the music-energy range despite Klipsch’s horn-loaded reputation for efficiency. In an A/B against a $118/pair Pioneer SP-BS22-LR, the R-41M had “no bass” and all mid-to-treble energy; the reviewer’s verdict was “please avoid the Klipsch R-41M unless you just want a speaker as an ornament.”
