Short answer: the Perlisten A3m on measured sound quality, the Triangle Borea BR03 on price. The Perlisten A3m ranks #51 of 222 bookshelf speakers, rated 4.2/5, at $3,000. The Triangle Borea BR03 ranks #198, rated 2.8/5, at $399, $2,601 cheaper.
The Triangle Borea BR03 is the deeper-bass pick. A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. Its bass reaches about 57Hz before falling 3dB, against 85.8Hz for the Perlisten A3m. The catch: A noticeable mid-range suckout, most pronounced in the upper mid-range/lower treble, that the reviewer attributes to cabinet resonances and driver breakup rather than a deliberate voicing choice: it makes vocals and instruments sound recessed and thin rather than warm.
The Perlisten A3m is the better-sounding option. 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.
Buy the Triangle Borea BR03 if the price matters more than sound quality. Buy the Perlisten A3m if sound quality matters more than the price.
