Short answer: the Revel Concerta2 F35 for better sound quality, the Linkwitz Lab LXmini for the lower price. The Revel Concerta2 F35 ranks #23 of 71 floorstanding speakers at $900. The Linkwitz Lab LXmini ranks #37 at $505, $395 cheaper.
What the Revel Concerta2 F35 offers: Two-and-a-half-way, four-driver design: a 1” aluminum dome tweeter on a waveguide, a 5.25” mid-range, and dual 5.25” mid-bass drivers in a rear-ported cabinet. Measured sensitivity of 89.4dB closely matches the 90dB spec, and distortion looks good at both 86dB and 96dB, holding up well even with a high-pass filter applied. At its sale price (around $900/pair, down from full retail), the reviewer calls it a “no-brainer,” undercutting comparable budget floorstanders like the ELAC DF63. Frequency response and directivity mismatches are largely EQ-able, since most of what shows up in measurements traces to physical tweeter/mid-range separation rather than a fundamental flaw. Compression is fairly well controlled for the price - about 1dB of loss around 100Hz under long-term compression, described as “par for the course” at this cost. Watch for: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension. A dip in the lower midrange/2-3kHz region reduces attack and detail, and a peak around 5kHz adds some edge and sibilance in the lower treble. A peak in off-axis energy around 3kHz reflects off sidewalls at roughly 60-70° off-axis and arrives louder than the direct sound - this specific issue can’t be fixed with EQ (boosting the direct sound would boost the stronger reflection too) and would need acoustic absorption to properly address, though the reviewer considers it a minor, optional fix at this price. A couple of minor resonances appear in the impedance plot, including one around 300Hz that may partly explain a subtle sense of vocal warmth noticed in listening, though it’s more likely room-related. Minimum impedance around 3.8 ohms. Short-term compression testing shows some increased distortion in the tweeter and higher-frequency compression at loud output.
What the Linkwitz Lab LXmini offers: Open-baffle/dipole upper driver and cylindrical woofer enclosure create a very large, open soundstage with unusually little cabinet signature. Erin praised the stable, well-controlled directivity: despite using a nominal full-range upper driver, off-axis response retains composure beyond its beaming region and the directivity index is smooth enough for reliable DSP voicing. Imaging can be precisely adjusted through placement and toe angle. Erin measured F3 at 50Hz and F10 at 33Hz, impressive for the narrow footprint, and found the system satisfying for much music without a subwoofer. The supplied miniDSP configuration is readily editable; broad shelf correction near 550Hz and a handful of narrow filters can make the response substantially more linear. The kit is mechanically simple, highly customizable and based on well-documented Linkwitz engineering. Watch for: This is not a conventional passive pair: it requires a construction-plan license, assembly, miniDSP, four matched amplifier channels and careful gain/setup work, so the apparent kit price is not the complete system cost. Output below about 50Hz lacks kick-drum weight and benefits from subwoofers. Erin found rising second-order distortion near 1.5kHz on both samples, accompanied by an impedance blip that may indicate an enclosure reflection or driver-compliance effect. At high output the system behaves as if electronically limited even with miniDSP limiting bypassed, reducing bass and subjective dynamics. Default voicing is less linear than expected, with irregularities above roughly 2kHz, though its controlled directivity makes these correctable. Dipole rear radiation demands meaningful distance from the front wall and makes placement less flexible than a box speaker.
Buy the Revel Concerta2 F35 if sound quality matters more than the price. Buy the Linkwitz Lab LXmini if the price matters more than sound quality.
