Audio First Cadentia 3 vs Triangle Borea BR03

What the Audio First Cadentia 3 offers: Near-textbook measurements - excellent on-axis linearity, listening window, and directivity, with only minor deviations. Extremely low distortion and compression, holding steady even at 102dB with barely any loss. Very wide, consistent horizontal dispersion (~70 degrees) gives a big, enveloping soundstage with strong image specificity outside the speaker boundaries. Strong bass extension for a bookshelf (F3 43Hz, F10 26Hz) with a punchy, guttural mid-bass. Watch for: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants - fixable with a single-band EQ (2.5kHz, +1dB, Q~1). High-frequency dispersion narrows quickly above about 4kHz, so off-axis listeners lose some air and detail. Very high asking price for a bookshelf-class speaker, and the complete (finished) version has a long lead time; the loaner kit version ships as an unfinished cabinet you assemble and finish yourself.

What the Triangle Borea BR03 offers: Bass output is genuinely decent for the price - measured extension reaches F3 57Hz/F10 42Hz, which the reviewer had no real complaints about. Dual front-firing ports and a well-stuffed, well-braced cabinet. Solid build quality overall. Watch for: 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. Sibilance in the 4-8kHz region shows up on every track the reviewer tried. Measured minimum impedance dips to about 4.2 ohms (with an even lower EPDR), despite the speaker and its own rear panel being labeled 8 ohms - worth knowing if you’re planning to drive these with a receiver/AVR that assumes an 8-ohm nominal load. The reviewer is upfront that this speaker has a devoted following among other reviewers, but says he specifically doesn’t hear what they hear and wants people who own it to trust their own ears rather than assume something’s wrong with their hearing if they don’t love it either.
