Short answer: the MoFi SourcePoint 8. Both are rated 4.5/5 for sound quality (#17 and #22 of 214 bookshelf speakers), and the MoFi SourcePoint 8 costs $2,594 against $2,999.95 for the Revel Performa4 M146, so with nothing between them on sound quality, price settles it.
Why pick the MoFi SourcePoint 8: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. The tradeoff: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
Why pick the Revel Performa4 M146: The larger Performa4 standmount, pairing a 6.5” ceramic composite woofer with a 1” ceramic dome tweeter in Revel’s seventh generation Acoustic Lens waveguide, crossed over at 1.7kHz. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Revel M106.
Buy the MoFi SourcePoint 8. Both are rated the same for sound quality, and it costs $405.95 less than the Revel Performa4 M146.
About the ratings: the Revel Performa4 M146’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.1 to 4.8, so this verdict could change once it is measured.

MoFi SourcePoint 8: $2594 per pair Crutchfield eBay
Same family: the MoFi SourcePoint 10 (larger bookshelf, ranked lower, rated 4.4/5) and the MoFi SourcePoint 888 (floorstanding, rated 4.7/5). See every MoFi SourcePoint generation.
Pros: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. Notably more neutral and true-to-source than its sibling MoFi SourcePoint 10, which the reviewer found a bit too bright in the treble by comparison: measured about 4-5dB less high-frequency output. Excellent imaging: passed multiple stereo-panning and depth tests, including smooth continuous left-to-right pans without wobble and correct front-to-back layering of vocals versus percussion. Wide horizontal dispersion of about ±60°, broader than the reviewer expected from a coaxial design, and forgiving enough in placement that about 10° of toe-out variance and moving above or below the tweeter axis both still sound good. Excellent dynamic range and compression linearity: about 26dB of headroom up to 102dB/1m equivalent, with issues only appearing below about 60Hz. 8-ohm nominal impedance made it easy to drive on everything from a budget Denon AVR to a high-end Macintosh amplifier. No significant evidence of woofer-cone modulation distortion affecting the tweeter, even at 96dB/1m. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out. The rear-ported cabinet (two ports) means it can’t be placed too close to a wall without the bass becoming overblown: the reviewer settled on about 2 feet of clearance. F3 of 52Hz and F10 of 43Hz mean genuine deep bass tops out in the mid-40s Hz in-room: a subwoofer is still needed for true low-end extension. Harmonic distortion crosses the reviewer’s 3% threshold at 96dB (though it’s second-order and less audibly significant), and multitone distortion becomes noticeably more audible at that same output level. Vertical response doesn’t perfectly mirror horizontal, since the cabinet is a rectangle rather than a perfect square around the driver.

Revel Performa4 M146: $2,999.95 per pair Estimated Audio Advice eBay
Same family: the Revel Performa4 M145 (smaller bookshelf, estimated 4.3/5), the Revel Performa4 F345 (smaller floorstanding, estimated 4.4/5), the Revel Performa4 F346 (larger floorstanding, estimated 4.5/5) and the Revel Performa4 C245 (center, estimated 4/5). See every Revel Performa generation.
Pros: The larger Performa4 standmount, pairing a 6.5” ceramic composite woofer with a 1” ceramic dome tweeter in Revel’s seventh generation Acoustic Lens waveguide, crossed over at 1.7kHz. Its measured predecessor, the Revel M106, scored a 5.62 Spinorama preference score (7.87 with a subwoofer), and the bigger woofer reaches 43Hz (-6dB) for fuller bass than the Revel Performa4 M145. Dual binding posts allow bi-wiring.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Revel M106. Sensitivity is only 85.5dB, so it wants more amplifier power than most bookshelf speakers, and at 359mm tall and 11kg it needs sturdy stands.
