Short answer: the MoFi SourcePoint 8 for better sound quality, the Revel Performa M22 for the lower price. The MoFi SourcePoint 8 ranks #17 of 125 bookshelf speakers at $2200. The Revel Performa M22 ranks #92 at $600, $1600 cheaper.
What the Revel Performa M22 offers: Very flat frequency response from 200hz to 10khz. Distortion is well controlled through most of the range, with only a modest crossover-region bump around 2-4kHz. Watch for: 3dB bass boost around 100hz. On-axis response also droops below 150Hz and peaks above 4kHz, which the reviewer thought may sound a bit bright/light. Distortion rises substantially below 100Hz when driven hard.
What the MoFi SourcePoint 8 offers: 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 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. Watch for: 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.
Buy the Revel Performa M22 if the price matters more than sound quality. Buy the MoFi SourcePoint 8 if sound quality matters more than the price.
