Audio First Cadentia 3 vs Triangle Borea BR03

The Audio First Cadentia 3 is the more accurate, deeper-bass pick. Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 4.03 for the Triangle Borea BR03. Its bass reaches about 43Hz before falling 3dB, against 57Hz for the Triangle Borea BR03. The tradeoff: 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).

Why pick the Triangle Borea BR03: Bass output is genuinely decent for the price: measured extension reaches F3 57Hz/F10 42Hz, which the reviewer had no real complaints about. 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.

Frequency Response Compared

Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

Listening window: the sound arriving straight at you, averaged over a small window around the listening position.

Estimated in-room response: what a typical room adds: reflections from walls and the floor make it tilt down toward the treble, and a gentle, even tilt is ideal.
