Short answer: the Emotiva Airmotiv XB2 for better sound quality, the Triangle Borea BR03 for the lower price. The Emotiva Airmotiv XB2 ranks #40 of 130 bookshelf speakers at $549. The Triangle Borea BR03 ranks #109 at $399, $150 cheaper.
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.
What the Emotiva Airmotiv XB2 offers: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value - rated a top-three performer for the money by Erin’s Audio Corner. Watch for: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener - needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.
Buy the Triangle Borea BR03 if the price is the priority over sound quality, or the Emotiva Airmotiv XB2 if sound quality is the priority over the price.
