Short answer: the Revel Concerta2 F35. It ranks #31 of 226 floorstanding speakers by sound quality, rated 4.5/5, at $900. The Linkwitz Lab LXmini ranks #86, rated 4.2/5, at $505, $395 cheaper, which does not close the gap in sound quality.
The Revel Concerta2 F35 is the more accurate choice. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.35 against 3.89 for the Linkwitz Lab LXmini. Watch for: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension.
The Linkwitz Lab LXmini is the deeper-bass option. Open-baffle/dipole upper driver and cylindrical woofer enclosure create a very large, open soundstage with unusually little cabinet signature. Its bass reaches about 50Hz before falling 3dB, against 70Hz for the Revel Concerta2 F35. The catch: 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.
Buy the Revel Concerta2 F35. It is rated higher for sound quality, and saving $395 with the Linkwitz Lab LXmini does not make up for the sound-quality gap.

Revel Concerta2 F35: $900 per pair Crutchfield eBay
Same family: the Revel Concerta2 M16 (bookshelf, rated 4.1/5), the Revel Concerta2 F36 (larger floorstanding, ranked higher, estimated 4.6/5) and the Revel Concerta2 C25 (center, rated 4.1/5).
Pros: 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 of $900/pair, down from full retail, the reviewer calls it a “no-brainer,” undercutting comparable budget floorstanders like the ELAC Debut 3.0 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. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: 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.

Linkwitz Lab LXmini: $505.00 per pair Madisound LXmini Kit eBay
Pros: 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. Measured bass extension of 50Hz (-3dB).
Cons: 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.
