Short answer: the SVS Prime Bookshelf. It ranks #63 of 100 bookshelf speakers by sound quality at $699; the JBL XPL-90 ranks #71 and costs $1298, so there is not much of a tradeoff to weigh.
The case for the SVS Prime Bookshelf: 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 tradeoff: 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 JBL XPL-90 gets right: Nearly ruler-flat on-axis response up to 1kHz with even horizontal directivity until the tweeter beams above 10kHz. The catch: Crossover region peaking around 3kHz and treble peaking above 10kHz color the top end, and poor vertical directivity means the tweeter needs to be at ear level.
Buy the SVS Prime Bookshelf. It ranks higher for sound quality than the JBL XPL-90 and costs less, so there is no real case for the other one.

The Two Speakers In Full
SVS Prime Bookshelf: $699.00 Amazon
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.
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.

JBL XPL-90: $1,298 used, discontinued (vintage, late 1980s)
Pros: Nearly ruler-flat on-axis response up to 1kHz with even horizontal directivity until the tweeter beams above 10kHz. The reviewer found real strength with vocals and simpler instrumentation, calling it “the first speaker I have liked that has some clear response errors” and “an enjoyable speaker” despite the flaws. Titanium tweeter and internal Monster cable wiring reflect JBL’s higher-end late-1980s engineering.
Cons: Crossover region peaking around 3kHz and treble peaking above 10kHz color the top end, and poor vertical directivity means the tweeter needs to be at ear level. Distortion rises at 96dB SPL, especially around 3kHz. Long discontinued; only available on the used market.
