Short answer: the Klipsch RP-600M II. It ranks #114 of 203 bookshelf speakers by sound quality (rated 3.7/5) at $449.99 and is still sold new; the B&W 805S ranks #180 (rated 2.8/5) and is discontinued, so it is only an option used. The B&W 805S’s replacement, the Bowers & Wilkins 805 D5, is rated 3.3/5.
The Klipsch RP-600M II is the more accurate pick. Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original Klipsch RP-600M. Its measured preference score, a predictor of how neutral it sounds, is 5.64 against 4.12 for the B&W 805S. Watch for: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
The B&W 805S is the deeper-bass choice. Bass and dynamic performance are strong for the cabinet size, playing very loud with well-controlled bass distortion. Its bass reaches about 46.9Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. The catch: CEA2034 spinorama shows directivity breaking down badly starting around 1kHz and staying poor to 3kHz: a wide crossover-region flaw the reviewer called “clearly flawed execution” that leaves vocals sounding recessed and masked without EQ correction.
Buy the Klipsch RP-600M II. It is rated higher for sound quality, and the B&W 805S is discontinued, so it is only available used.

Klipsch RP-600M II: $449.99 per pair Amazon eBay
Older model: the Klipsch RP-600M (ranked lower, rated 2.9/5).
Same family: the Klipsch RP-500M II (smaller bookshelf, rated 4/5), the Klipsch RP-5000F II (smallest floorstanding, rated 4/5), the Klipsch RP-6000F II (floorstanding, rated 3.9/5), the Klipsch RP-8000F II (largest floorstanding, rated 3.9/5), the Klipsch RP-404C II (smallest center, rated 3.7/5), the Klipsch RP-500C II (center, rated 3.9/5) and the Klipsch RP-504C II (largest center, rated 3.8/5).
Pros: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original Klipsch RP-600M. Roughly 10-20° wider horizontal radiation than the original, giving more soundstage envelopment while retaining precise imaging. A major step up in overall tonal neutrality compared to the original Klipsch RP-600M, largely eliminating that model’s midrange resonance issues. Unusually, sounds better with the grille on: the grille smooths out the elevated treble rather than degrading the sound, a rare trait among speakers the reviewer has tested. More refined back-panel hardware, including anodized binding posts and jumper cables for optional bi-amping. Responds well to EQ correction (verified using measurement software and a miniDSP), letting the on-axis response be made genuinely linear. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 86dB.
Cons: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced. Horizontal dispersion is very slightly less linear across angles than the original Klipsch RP-600M, a minor trade-off for the wider overall radiation pattern. Klipsch’s marketed sensitivity (about 94.5dB) is, like the original, a half-space rating roughly 9dB above the anechoic reality (closer to 85-86dB). In-room bass rolls off around 60Hz in practice, and a 120Hz boost paired with a midrange scoop gives kick drums their “tambour” without real low-end weight: a subwoofer is still recommended. Vertical listening tolerance is limited to about ±10° from the tweeter axis. Toeing the speaker out for better on-axis tonality (rather than using the grille) introduces slightly more diffuse imaging from added sidewall reflections.

B&W 805S: $2,500 per pair Discontinued eBay
Newer model: the Bowers & Wilkins 805 D5, ranked higher, estimated 3.3/5.
Pros: Bass and dynamic performance are strong for the cabinet size, playing very loud with well-controlled bass distortion. Horizontal beamwidth stays reasonably smooth through -6dB. Build quality has enough of a “quality feel” that the reviewer said it kept the speaker from the lowest possible rating. Measured bass extension of 46.9Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: CEA2034 spinorama shows directivity breaking down badly starting around 1kHz and staying poor to 3kHz: a wide crossover-region flaw the reviewer called “clearly flawed execution” that leaves vocals sounding recessed and masked without EQ correction. A high 4kHz crossover point appears to leave the tweeter’s small sub-enclosure resonating audibly during playback. Discontinued, superseded by the 805 Diamond/B&W 805 D4 series.
