#110 Triangle Borea BR03: $398.00 per pair Amazon eBay

Pros: 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. Measured bass extension of 57Hz (-3dB), with a measured sensitivity of 87.5dB.

Cons: 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.

How it compares: Just above it: Wharfedale Diamond 9.1 - 0.5Hz lower bass extension (-3dB). Just below it: B&W 805S - $2102 more, 1Hz lower bass extension (-3dB).
