The Two Speakers In Full
Revel M126Be: $4,400 per pair Crutchfield eBay
Older model: the Revel M106 (ranked higher, rated 4.6/5).
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 Revel’s less expensive M106 and 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.

Emotiva Airmotiv XB2: $549 per pair Emotiva eBay
Older models: the Emotiva B1+ (rated 4.1/5) and the Emotiva Airmotiv B2+ (ranked lower, rated 3/5).
Pros: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value: rated a top-three performer for the money by Erin’s Audio Corner. Measured bass extension of 62Hz (-3dB).
Cons: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener: needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.
