Short answer: the MoFi SourcePoint 10. Both are rated 4.4/5 for sound quality (#27 and #23 of 222 bookshelf speakers), and the MoFi SourcePoint 10 costs $3,795 against $6,000 for the Arendal 1528 Monitor 8, and with sound quality even, the cheaper one is the better buy.
The Arendal 1528 Monitor 8 is the more accurate, 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 measured preference score, a predictor of how neutral it sounds, is 5.59 against 4.16 for the MoFi SourcePoint 10. Its bass reaches about 41Hz before falling 3dB, against 56Hz for the MoFi SourcePoint 10. Watch for: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker.
The case for the MoFi SourcePoint 10: A large bookshelf speaker with a 10 inch concentric driver that acts like a point source, with a huge soundstage and strong, clean dynamics. The tradeoff: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate for the 28mm tweeter’s earlier beaming versus a typical 25mm/1” tweeter) combined with a diffraction dip/peak from the waveguide edge; needs about 15° of toe-out to sound neutral, and even then benefits from an extra 1-2dB of treble EQ.
Buy the MoFi SourcePoint 10. Both are rated the same for sound quality, and it costs $2,205 less than the Arendal 1528 Monitor 8.
