Short answer: the SVS Prime Bookshelf. It ranks #144 of 214 bookshelf speakers by sound quality, rated 3.5/5, at $699. The Triangle Borea BR04 ranks #184, rated 3.0/5, at $649, $50 cheaper, not enough of a saving to outweigh the sound-quality gap.
The SVS Prime Bookshelf is the better-sounding pick. 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. The catch: 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.
What the Triangle Borea BR04 does well: A larger Triangle Borea BR03 with a 6.3” cellulose woofer and a front port, rated from 44Hz at 90dB, so it is easy to drive and can sit near a wall. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the SVS Prime Bookshelf. It is rated higher for sound quality, and the $50 saving on the Triangle Borea BR04 is not enough to make up the difference.
Worth knowing: the Triangle Borea BR04 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.7 to 3.3, so treat this verdict as provisional.

The Two Speakers In Full
SVS Prime Bookshelf: $699.00 per pair Amazon eBay
Same family: the SVS Prime Satellite (smaller bookshelf, estimated 3.3/5), the SVS Prime Tower (smaller floorstanding, estimated 3.6/5), the SVS Prime Pinnacle (larger floorstanding, estimated 3.8/5), the SVS Prime Center (center, rated 3.4/5) and the SVS Prime Elevation (surround, estimated 3.3/5).
Pros: 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. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 87dB.
Cons: 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.
