Short answer: the SVS Prime Bookshelf for better sound quality, the Triangle Borea BR03 for the lower price. The SVS Prime Bookshelf ranks #88 of 130 bookshelf speakers at $699. The Triangle Borea BR03 ranks #109 at $399, $300 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 SVS Prime Bookshelf offers: Reasonable sensitivity for the price at about 87dB, and the 6.5” woofer sits in its own dedicated sealed sub-compartment inside the cabinet for cleaner midrange/bass separation. Overall response stays within about ±3dB from 80Hz-16kHz, which the reviewer calls reasonable for the price point. Wide, consistent horizontal radiation. Toeing the speakers 30 degrees off-axis smooths the in-room response noticeably if the on-axis tonal balance isn’t to your taste. Watch for: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range. Measured minimum impedance dips below 4 ohms (EPDR even lower), so an 8-ohm-only amplifier or AVR may struggle - a 4-ohm-stable amp or separate amplification is recommended. Bass extension is modest (F3 72Hz, F10 49Hz measured) - SVS clearly designed this to be paired with one of their subwoofers rather than to stand fully alone. Compared directly against its pricier sibling, the SVS Ultra Bookshelf, in the same review, the reviewer found the Ultra noticeably more tonally neutral.
Buy the Triangle Borea BR03 when the price outweighs sound quality for you, and the SVS Prime Bookshelf when sound quality outweighs the price instead.
The Triangle Borea BR03 is not a sound-quality pick. It sits near the bottom of the 130 bookshelf speakers; there are better options higher up.
