Short answer: the JBL XPL-90 for better sound quality, the Emotiva Airmotiv B2+ for the lower price. The JBL XPL-90 ranks #71 of 100 bookshelf speakers at $1298. The Emotiva Airmotiv B2+ ranks #72 at $449, $849 cheaper.
What the JBL XPL-90 offers: Nearly ruler-flat on-axis response up to 1kHz with even horizontal directivity until the tweeter beams above 10kHz. Watch for: 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.
The case for the Emotiva Airmotiv B2+: Erin measured a useful 86dB average sensitivity and strong midbass punch around 120Hz. The tradeoff: The replacement B2+ did not deliver the neutral upgrade Erin expected.
Buy the JBL XPL-90 if sound quality matters more than the price. Buy the Emotiva Airmotiv B2+ if the price matters more than sound quality.

The Two Speakers In Full
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.

Emotiva Airmotiv B2+: $449.00
Pros: Erin measured a useful 86dB average sensitivity and strong midbass punch around 120Hz. The folded-ribbon tweeter provides very broad upper-treble radiation, and the speaker can create a spacious presentation when positioned carefully. Response and directivity remain reasonably orderly below the roughly 2kHz crossover region. The 6.5-inch woofer offers more output capability than compact 5-inch competitors, while F3/F10 of 66/43Hz leave adequate overlap for a conventional 80Hz subwoofer crossover. Horizontal directivity data makes the broad baffle-step trend amenable to partial EQ below the crossover.
Cons: The replacement B2+ did not deliver the neutral upgrade Erin expected. A baffle-step loss around 500Hz depresses the lower midrange while the AMT’s much wider radiation above crossover injects excess room energy, yielding a bright, forward balance and false impression of cymbal detail. The directivity discontinuity near 2kHz cannot be completely equalized. Erin measured F3 at 66Hz and F10 at 43Hz, so meaningful kick-drum fundamentals and low bass still need a subwoofer. Vertical listening tolerance is roughly +/-10 degrees, with best results between the top of the woofer and tweeter axes. Broad lateral treble energy may require careful toe-out and sidewall absorption. Despite a large cabinet, it offers limited deep-bass advantage and was not Erin’s hoped-for successor to the more linear B1+.
