Short answer: the ELAC DF63 for better sound quality, the Linkwitz Lab LXmini for the lower price. The ELAC DF63 ranks #25 of 54 floorstanding speakers at $649. The Linkwitz Lab LXmini ranks #27 at $505, $144 cheaper.
What the ELAC DF63 offers: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed… Watch for: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals.
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. 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.
Buy the ELAC DF63 if sound quality matters more than the price. Buy the Linkwitz Lab LXmini if the price matters more than sound quality.

Pros: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. The dedicated midrange driver keeps distortion low even at higher output, avoiding the intermodulation grain typical of two-way bookshelf designs. The waveguide keeps high-frequency directivity well controlled, and overall horizontal directivity is good up to about 2kHz. Harmonic distortion looks good at both 86dB and 96dB, and multitone distortion stays below the reviewer’s 3% threshold. A shallow bass rolloff (F3 71Hz, F10 29Hz) lets it extend fairly low without a hard cutoff. Preferred by the reviewer over the similarly-priced Polk R500 (too much high-frequency narrowing, less neutral) and considered ahead of the Polk R700 as well.
Cons: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals. A mild peak around 10kHz makes shakers and similar high-frequency percussion jump too far forward in the mix; needed about 2dB of EQ to tame in testing. A dip in the 1-3kHz range gives the speaker a warm, slightly veiled character - the reviewer suspects the tweeter crossover point (around 2-3kHz) is set a bit high and could be lowered to fill this in. Directivity shows a noticeable handoff mismatch around 2.5kHz where the midrange driver hands off to the tweeter, though it’s minor at the -6dB point. Vertical directivity is narrower than horizontal, so listeners need to stay close to the tweeter axis. Low EPDR (about 1.5 ohms minimum) means a Class AB amplifier should be well-ventilated. Best positioned pointed directly at the listener and closer to the front wall - toeing it out into the room causes too much high-frequency rolloff.

Linkwitz Lab LXmini: $505.00 Madisound LXmini Kit
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.
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.
