Short answer: the Arendal 1528 Monitor 8 for better sound quality, the Polk Signature Elite ES20 for the lower price. The Arendal 1528 Monitor 8 ranks #23 of 222 bookshelf speakers, rated 4.4/5, at $6,000. The Polk Signature Elite ES20 ranks #119, rated 3.7/5, at $398.98, $5,601.02 cheaper.
What the Polk Signature Elite ES20 does well: Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. Watch for: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
The Arendal 1528 Monitor 8 is the more accurate, deeper-bass pick. 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 4.49 for the Polk Signature Elite ES20. Its bass reaches about 41Hz before falling 3dB, against 55.7Hz for the Polk Signature Elite ES20. The tradeoff: A dip in the midbase around 100Hz noticeably reduces the “chestiness” of male vocals compared to the reviewer’s reference speaker.
Buy the Polk Signature Elite ES20 when the price outweighs sound quality for you, and the Arendal 1528 Monitor 8 when sound quality outweighs the price instead.
