Short answer: the Revel M126Be if sound quality matters most, the Klipsch RP-600M II if price matters most. The Revel M126Be ranks #39 of 203 bookshelf speakers, rated 4.3/5, at $4,400. The Klipsch RP-600M II ranks #114, rated 3.7/5, at $449.99, $3,950.01 cheaper.
The Klipsch RP-600M II is the more accurate, deeper-bass choice. 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 5.08 for the Revel M126Be. Its bass reaches about 70Hz before falling 3dB, against 103Hz for the Revel M126Be. The catch: 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 Revel M126Be is the better-sounding pick. Two-way design pairing a 6.5” midwoofer with a 1” beryllium dome tweeter, the smaller sibling to the reviewer’s favorite Revel F226Be. The tradeoff: At $2200/pair, the reviewer doesn’t consider it a strong value: an improvement over the less expensive Revel M106 and other Performa3 models, but not proportional to the price jump.
Buy the Klipsch RP-600M II if the price matters more than sound quality. Buy the Revel M126Be if sound quality matters more than the price.

The Two Speakers In Full
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.

Revel M126Be: $4,400 per pair Crutchfield eBay
Older model: the Revel M106 (ranked higher, rated 4.6/5).
Same family: the Revel F226Be (smallest floorstanding, rated 4.6/5), the Revel F228Be (floorstanding, rated 4.5/5), the Revel F328Be (largest floorstanding, rated 4.7/5) and the Revel C426Be (center, rated 4/5).
Pros: Two-way design pairing a 6.5” midwoofer with a 1” beryllium dome tweeter, the smaller sibling to the reviewer’s favorite Revel F226Be. Wide, immersive stereo imaging: hard-panned sounds in test tracks localized 2-3 feet outside the physical speaker positions without losing pinpoint precision. Horizontal radiation of about 60-70°, landing right in the reviewer’s preferred range for an enveloping yet still well-focused soundstage. Extended bass-shelf tuning (similar in concept to the KEF R3 Meta) combines with in-room gain for a more linear low end rather than a boomy hump. Diffraction dips visible on-axis around 3kHz and 7kHz largely disappear in the estimated in-room response, since they fill in as you move off-axis. Distortion stays within 3% down to about 100Hz at both 86dB and 96dB output: strong performance for a 6.5” bookshelf woofer. Can be driven by a standard AVR thanks to a manageable 4.9-ohm minimum impedance. Measured bass extension of 103Hz (-3dB), with a measured sensitivity of 86.1dB.
Cons: At $2200/pair, the reviewer doesn’t consider it a strong value: an improvement over the less expensive Revel M106 and other Performa3 models, but not proportional to the price jump. Bass tops out around 50Hz in-room; a subwoofer is still needed for real low-end extension. Vertical placement is fairly critical: there’s a notable hole in the response around the 1.7kHz crossover if you sit above the tweeter axis. Toeing the speaker out to a full 30° introduces a roughly 1dB discontinuity in the midrange along with high-frequency rolloff; the reviewer recommends staying close to on-axis or within about 10°. An unexplained jump in distortion appears right at the 1.7kHz crossover point under compression testing, which may be linked to an occasional “glaring” quality the reviewer noticed in the 2-3kHz region at very high volumes (92-93dB from 2 meters). A mild 2-3kHz forwardness occasionally stood out on some tracks, correctable with about 1dB of EQ, though the reviewer considers it minor.
