Short answer: the MoFi SourcePoint 8. It ranks #17 of 222 bookshelf speakers by sound quality, rated 4.5/5, at $2,594; the Arendal 1528 Monitor 8 ranks #23, rated 4.4/5, and costs $6,000, so there is not much of a tradeoff to weigh.
The case for the MoFi SourcePoint 8: A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. 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.
The Arendal 1528 Monitor 8 is the deeper-bass option. A big three way monitor with dual 8 inch woofers, bass deep enough to skip a subwoofer, and extremely low distortion at high volume. Its bass reaches about 41Hz before falling 3dB, against 52Hz for the MoFi SourcePoint 8. Watch for: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker.
Buy the MoFi SourcePoint 8. It is rated higher for sound quality than the Arendal 1528 Monitor 8 and costs less, so only choose the other one for a particular feature it does better.
