Short answer: the Ascend Acoustics Sierra-LX. It ranks #37 of 222 bookshelf speakers by sound quality, rated 4.3/5, at $1,598; the Perlisten A3m ranks #51, rated 4.2/5, and costs $3,000, so there is little reason to consider the other one.
The Ascend Acoustics Sierra-LX is the more accurate, deeper-bass pick. A compact bookshelf speaker with very neutral, flat sound, a wide soundstage, and surprisingly deep bass in a bamboo cabinet. Its measured preference score, a predictor of how neutral it sounds, is 6.63 against 4.30 for the Perlisten A3m. Its bass reaches about 47Hz before falling 3dB, against 85.8Hz for the Perlisten A3m. The tradeoff: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels.
Why pick the Perlisten A3m: A sealed high output monitor with dual 8 inch woofers and a waveguide tweeter, a great match for a subwoofer in a home theater. The catch: 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.
Buy the Ascend Acoustics Sierra-LX. It is rated higher for sound quality than the Perlisten A3m and costs less, so only choose the other one for a particular feature it does better.
