#32 PS Audio Aspen FR10: $12000 Psaudio eBay
Pros: Distinctive driver layout: two 6” mid-bass drivers plus three 6x9” passive radiators, an 8” planar ribbon mid-range, and a 2.5” planar ribbon tweeter, with the woofers placed low near the floor to counteract typical floor-bounce cancellation in the mid-bass/lower-midrange handoff. Deliberately shelved bass response around 150Hz allows placement closer to the rear wall than typical, without the usual boominess. Extremely wide horizontal dispersion (the -6dB point isn’t reached until about 80-85° off-axis), giving a wide, enveloping soundstage that stays consistent rather than narrowing unevenly at different frequencies. Passed multiple stereo-imaging tests with precise placement despite the wide radiation, keeping instruments distinctly separated even in complex, heavily panned tracks. Exceptionally low multitone distortion at high frequency - among the best the reviewer has measured on any speaker. Bass extends smoothly to an F3 of 47Hz and F10 of 28Hz, potentially usable without a subwoofer for material that doesn’t dig much below 40Hz. Shows output enhancement rather than compression below about 50Hz even at high volume, adding extra punch and attack to bass transients.
Cons: At roughly $10,000/pair, expectations are high, and the reviewer found some measured shortfalls relative to that price. A scoop around 600Hz slightly thins out vocal fullness; EQ can restore some body there. A narrow but pronounced dip around 6-7kHz shows up in measurements, though EQ didn’t meaningfully improve it in testing and the reviewer says he’d rather have a dip than a peak in that sibilance-prone region. On-axis, the treble reads as mildly elevated (though far less than some rivals like Martin Logan or Focal); needs about 20° of toe-out, per the manufacturer’s own recommendation, to sound properly balanced and take on a warmer character. Sidewall acoustic treatment should be avoided, since the speaker’s wide, room-filling sound depends on that sidewall interaction, limiting setup flexibility in treated rooms. A minor resonance-like anomaly appears around 800Hz, and some compression shows up at the highest frequencies (around 12kHz) under extreme output testing, though unlikely to be audible in real listening. Large and heavy floorstander (about 76 lbs each, 41” tall).
How it compares: Just above it: Linkwitz Lab LXmini - $11495 cheaper, 0.6Hz higher bass extension (-3dB). Just below it: Definitive Technology BP-9020 - $11500 cheaper, 3.3Hz higher bass extension (-3dB).
