#86 Linkwitz Lab LXmini: $505.00 per pair Madisound LXmini Kit $505.00 eBay

Pros: A build it yourself DSP speaker with a huge, open soundstage, little cabinet sound and surprising bass for its narrow size. 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.
