Short answer: the Perlisten A3m on measured sound quality, the Polk Signature Elite ES20 on price. The Perlisten A3m ranks #51 of 222 bookshelf speakers, rated 4.2/5, at $3,000. The Polk Signature Elite ES20 ranks #119, rated 3.7/5, at $398.98, $2,601.02 cheaper.
The Polk Signature Elite ES20 is the deeper-bass option. Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. Its bass reaches about 55.7Hz before falling 3dB, against 85.8Hz for the Perlisten A3m. The catch: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
The Perlisten A3m is the better-sounding choice. A sealed high output monitor with dual 8 inch woofers and a waveguide tweeter, a great match for a subwoofer in a home theater. Watch for: The low-quality vendor Spinorama data measures only 85.8Hz at -3dB, 74.1Hz at -6dB, and 55.7Hz at -12dB, conflicting with Perlisten’s much deeper in-room extension claim.
