Short answer: the JBL XPL-90 is nearly ruler-flat to 1kHz, but the ELAC Debut 2.0 B6.2 is the more forgiving placement. The XPL-90 has even horizontal directivity until the tweeter beams above 10kHz, yet crossover peaking around 3kHz and treble peaking above 10kHz color the top end, and poor vertical directivity forces the tweeter to ear level. The B6.2’s 700Hz peak can be tamed about 5dB with EQ for a noticeable but not dramatic improvement.

ELAC Debut 2.0 B6.2: $479.00 per pair Amazon Crutchfield eBay
Pros: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity, holding about ±60° up to roughly 8kHz for consistent stereo width whether aimed directly at the listener or toed out. Its larger-than-typical woofer lets it play very loud with minimal distortion, staying under about 1% THD down to 50Hz at 86dB, and minimum impedance stays a comfortable 5-6 ohms. In-room bass extension reaches about 50Hz without much trouble, enough for a solid kick-drum sound. Takes equalization very well: correcting the on-axis response doesn’t cost sensitivity through the midrange, and the underlying directivity behavior (diffraction, vertical mismatch) is mild enough that EQ alone gets most of the way to a well-balanced sound. Vertical tolerance is asymmetric and fairly forgiving: about 10° above the tweeter axis and 20° below it before tonal balance meaningfully shifts. One reviewer called it “a good speaker” with “a good price” rather than just good-for-the-price, and found it fairly neutral overall in-room. Measured bass extension of 64Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: A good size resonant peak around 700Hz stands out from an otherwise smooth response and lingers in cumulative spectral decay (waterfall) measurements: in one reviewer’s sighted A/B test, reducing it by about 5dB via EQ made a noticeable but not dramatic difference. Directivity error shows up around 3.3kHz, and the upper-midrange around 4-6kHz stood out as edgy and sharp, almost sibilant at times, in casual listening: the predicted in-room response shows a lack of energy between 1-2kHz and a bit too much above that, which one reviewer thought would sound bright. Distortion at 96dB SPL/1m shows two harmonic peaks the reviewer says “should not be there,” one from woofer breakup around 400Hz and another around 7-8kHz from the tweeter, and multitone distortion approaches 10% in the 500-800Hz range at that output level. Real compression shows up even at moderate volume and worsens at 96dB and above, with the woofer clearly giving up around 60-70Hz: a subwoofer is recommended for anyone wanting to listen loud, since running it full-range at high output costs real dynamic range in the midbass and bass. Don’t place it close to a wall: boundary reinforcement adds a midbass bump that undoes the otherwise smooth, linear response. Getting the best out of it takes EQ (taming the 700Hz peak, filling in the 1-2kHz dip, and trimming the highs).

JBL XPL-90: $1,298 per pair used (vintage, late 1980s) Discontinued eBay
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. Measured bass extension of 77.6Hz (-3dB), with a measured sensitivity of 85dB.
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.
