#17 MoFi SourcePoint 8: $2594 per pair Crutchfield eBay

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 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.
