Short answer: the KEF R3 Meta. It ranks #10 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99; the MoFi SourcePoint 8 ranks #17, rated 4.5/5, and costs $2,594, so there is little reason to consider the other one.
The KEF R3 Meta is the more accurate choice. A three way bookshelf speaker with KEF’s coaxial driver, superb accuracy that holds across the room, and bass that reaches deep for its size. Its measured preference score, a predictor of how neutral it sounds, is 6.10 against 5.15 for the MoFi SourcePoint 8. The catch: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it.
The MoFi SourcePoint 8 is the deeper-bass choice. A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. Its bass reaches about 52Hz before falling 3dB, against 76Hz for the KEF R3 Meta. 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.
Buy the KEF R3 Meta. It is rated higher for sound quality than the MoFi SourcePoint 8 and costs less, which makes it the one to get unless you need something the other one does better.

Measured Differences
- Bass depth: the KEF R3 Meta reaches 37 Hz (10 dB down) against 43 Hz for the MoFi SourcePoint 8, about half an octave deeper. You hear more of the lowest bass notes and kick drums.
- Tonal accuracy above the bass: with a subwoofer taking the low end, the KEF R3 Meta scores 7.9 against 7.3 for the MoFi SourcePoint 8 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
