Short answer: the Ascend Sierra 1 v2. It ranks #3 of 160 bookshelf speakers by sound quality, rated 4.7/5, at $1,000. The Klipsch R-41M ranks #158, rated 1.3/5, at $141.55, $858.45 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Ascend Sierra 1 v2 is the more accurate, deeper-bass option. Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer, mated by a 4th-order acoustic crossover rather than a stock textbook design. Its measured preference score, a predictor of how neutral it sounds, is 6.65 against 3.04 for the Klipsch R-41M. Its bass reaches about 55Hz before falling 3dB, against 80Hz for the Klipsch R-41M. The catch: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material.
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 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 Ascend Sierra 1 v2. It is rated higher for sound quality, and the $858.45 saving on the Klipsch R-41M is not enough to make up the difference.

Ascend Sierra 1 v2: $1000 per pair Ascend Acoustics eBay
Same family: the Ascend Acoustics Sierra-2EX V2 (larger bookshelf, rated 4.3/5), the Ascend Acoustics Sierra-LX (larger bookshelf, rated 4.3/5), the Ascend Acoustics Sierra Titan Tower (floorstanding, rated 4.4/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5).
Pros: Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer, mated by a 4th-order acoustic crossover rather than a stock textbook design. In-room response is extremely linear (the reviewer called it “textbook”) a clear step up from the earlier V1, which had boxiness around 700Hz-1kHz and sibilance around 4-6kHz. Preference score of 8.4 with a subwoofer (6.8 without), which the reviewer calls topnotch. Wide, even horizontal radiation of about ±70° up to 6kHz. Better vertical directivity than its tweeter-to-woofer spacing would suggest, thanks to the steep 4th-order crossover slopes. No mechanical noise, port chuffing, or woofer bottoming even driven to 96dB/1m. In a three-way comparison against the Dynaudio Emit 20 and a Revel bookshelf model (all around $1,000/pair), measured as the most linear of the three and was the reviewer’s personal pick over both, despite the Dynaudio’s deeper bass and higher output capability. Independent ASR Klippel measurements corroborate Erin’s findings: superb off-axis response with only slight on-axis variations, and an in-room response the reviewer called “incredibly smooth and accurate. Amazing for a non-DSP speaker.” Distortion above 200Hz at 86dB/1m is very low for the class. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 81.5dB.
Cons: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material. Diffraction dips appear around 3kHz and 5-6kHz, and the 1” dome tweeter starts beaming above roughly 6.7kHz, narrowing the soundstage radiation in the top octave: a straightforward consequence of dome size rather than a design flaw. At 96dB/1m the 5.25” midwoofer shows increased distortion in the midrange, likely tied to motor topology; high-passing to a subwoofer around 80Hz largely clears it up. Moderate sensitivity (~81-82dB average) with a 7-ohm minimum impedance. ASR’s power-sweep testing found response holds steady up to 96dB SPL/1m, but pushing to 102dB causes midbass below 400Hz to sag with distortion “through the roof”: a harder output ceiling than the 96dB tests alone suggest. Vertical directivity also narrows above about 1kHz, so the reviewer recommends staying at tweeter-axis height for best results.

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.”
