Short answer: the Arendal 1528 Monitor 8 if sound quality matters most, the Ascend Acoustics CBM-170 SE2 if price matters most. The Arendal 1528 Monitor 8 ranks #23 of 222 bookshelf speakers, rated 4.4/5, at $6,000. The Ascend Acoustics CBM-170 SE2 ranks #113, rated 3.8/5, at $468, $5,532 cheaper.
The Ascend Acoustics CBM-170 SE2 is the more accurate choice. Compact two-way bookshelf speakers with a SEAS tweeter, a very flat midrange and smooth sound that suits most rooms. Its measured preference score, a predictor of how neutral it sounds, is 6.30 against 5.59 for the Arendal 1528 Monitor 8. The catch: A narrow dip in the on-axis and listening-window response appears in the 3-5kHz range (down to about -2.7dB), mirrored by a matching dip in the directivity index at the same frequencies: likely a brief widening of dispersion right at the tweeter/woofer crossover.
The Arendal 1528 Monitor 8 is the better-sounding, 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 70Hz for the Ascend Acoustics CBM-170 SE2. 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 Ascend Acoustics CBM-170 SE2 if the price is the priority over sound quality, or the Arendal 1528 Monitor 8 if sound quality is the priority over the price.
