Short answer: the Wharfedale Diamond 12.1i, if you are buying new. The Wharfedale Diamond 12.1 ranks higher than the Klipsch R-41M (#32 vs #166 of 168 bookshelf speakers) but is discontinued; its replacement, the Wharfedale Diamond 12.1i, is rated 4.0/5 at $499 and is still sold new.
The Wharfedale Diamond 12.1 is the more accurate, deeper-bass choice. A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Its measured preference score, a predictor of how neutral it sounds, is 5.01 against 3.04 for the Klipsch R-41M. Its bass reaches about 61Hz before falling 3dB, against 80Hz for the Klipsch R-41M. The tradeoff: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material: possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat.
The case for the Klipsch R-41M: Binding posts are unusually nice for the price point, and impedance is well controlled in the bass, easing the load on the amplifier. The tradeoff: 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 Wharfedale Diamond 12.1i, the replacement for the discontinued Wharfedale Diamond 12.1; it is rated higher for sound quality than the Klipsch R-41M.

Newer model: the Wharfedale Diamond 12.1i, ranked higher, estimated 4/5.
Older models: the Wharfedale Diamond 220 (ranked lower, rated 3.7/5), the Wharfedale Diamond 11.1 (ranked lower, estimated 3.7/5), the Wharfedale Diamond 10.1 (estimated 3.3/5) and the Wharfedale Diamond 9.1 (rated 2.8/5). See every Wharfedale Diamond generation.
Same family: the Wharfedale Diamond 12.0 (smaller bookshelf, ranked lower, estimated 3.1/5), the Wharfedale Diamond 12.2 (larger bookshelf, estimated 4.1/5), the Wharfedale Diamond 12.3 (smaller floorstanding, estimated 3.9/5), the Wharfedale Diamond 12.4 (larger floorstanding, estimated 4.1/5) and the Wharfedale Diamond 12.C (center, estimated 3.5/5).
Pros: A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Wide horizontal radiation of about ±60° up to roughly 5kHz before the tweeter starts to beam. Tonally smooth and easy to listen to at moderate volumes, with a pleasant, non-fatiguing character the reviewer said he’d happily recommend to someone who wants noticeably better fit, finish and looks than typical speakers in the $300-400 range. A high-pass crossover around 80Hz meaningfully cleans up midrange multitone distortion, so pairing it with a subwoofer helps more than usual for a speaker this size. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 84dB.
Cons: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material: possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat. Vertical directivity is unusually tight for this class of speaker, holding together only within about ±5° of the tweeter axis before a real hole opens up in the response, so seating height matters a lot more than on most bookshelf designs. Diffraction artifacts around 3kHz and 5kHz show up as differences between the listening-window and on-axis curves. Distortion climbs well past acceptable levels at higher output: harmonic distortion exceeds 3% around 150Hz at 96dB (versus under 1% at 86dB), multitone distortion tops 10% at 96dB/1m, and real compression sets in between 96-102dB (about 1.5dB of lost dynamic range around 300Hz at 102dB/1m, roughly equivalent to 92dB for a pair at 4m in a room). A genuine limitation on how loud or how far away this speaker can be pushed. Measured average sensitivity (84dB) runs a few dB below the 87dB spec. Only a 5” woofer, so a subwoofer is required for real bass. Discontinued.

Klipsch R-41M: $141.55 per pair Amazon eBay
Newer model: the Klipsch Reference R-40M, ranked higher, estimated 1.4/5.
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.”
