Short answer: the ELAC Uni-Fi Reference UBR62. Both are rated 4.1/5 for sound quality (#54 and #52 of 131 bookshelf speakers), and the ELAC Uni-Fi Reference UBR62 costs $1,199 against $1,350 for the Power Sound Audio MT-110-M, with sound quality a draw, the lower price decides it.
Why pick the Power Sound Audio MT-110-M: Made in the USA with a 1” polyimide compression tweeter on a cast aluminum exponential horn plus a 10” high-efficiency neodymium woofer, both BMS-made drivers. The catch: A mid-range bump makes the tonal balance sound too thick and needs 2-3 bands of EQ to flatten out; correcting it also pulls measured sensitivity down to about 90-91dB in practice.
What the ELAC Uni-Fi Reference UBR62 does well: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. The catch: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed.
Buy the ELAC Uni-Fi Reference UBR62. Both are rated the same for sound quality, and it costs $151 less than the Power Sound Audio MT-110-M.

Power Sound Audio MT-110-M: $1,350 per pair Power Sound Audio eBay
Pros: Made in the USA with a 1” polyimide compression tweeter on a cast aluminum exponential horn plus a 10” high-efficiency neodymium woofer, both BMS-made drivers. Reasonably high measured sensitivity (about 92.5dB at 2.83V/1m), so it doesn’t need much power to play loud. Excellent dynamic range: frequency response barely shifts (about 0.5dB deviation) from 76dB to 102dB output, which the reviewer calls completely acceptable headroom. Not fatiguing or bright despite the horn-loaded compression driver: the constant-directivity horn avoids the artificially flat, reflection-heavy in-room high-frequency buildup that some waveguide designs suffer from. Sealed cabinet design means placement near a wall is less of a bass-reinforcement concern than with a ported design. Solid build quality using threaded nutserts rather than screws driven directly into the cabinet wood. Measured bass extension of 113Hz (-3dB), with a measured sensitivity of 92.5dB.
Cons: A mid-range bump makes the tonal balance sound too thick and needs 2-3 bands of EQ to flatten out; correcting it also pulls measured sensitivity down to about 90-91dB in practice. F3 of 113Hz and F10 of 68Hz mean this doesn’t get low without a subwoofer: in the reviewer’s room it barely reached 70Hz with any real authority. Rising distortion in the upper mid-range, likely from woofer breakup, that lines up with anomalies seen in the impedance sweep above 500Hz: not a major concern but worth noting. The reviewer explicitly frames this as a home theater speaker rather than a stereo/music speaker.

ELAC Uni-Fi Reference UBR62: $1,199 per pair Amazon eBay
Pros: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. Erin found the directivity and overall tonality well controlled, with dual front slot vents minimizing placement sensitivity and cabinet bracing suppressing obvious coloration. The mostly 5-ohm-or-higher load is manageable for a genuinely 4-ohm-capable amplifier, and the coherent concentric upper range supports stable imaging across seats. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed. Impedance reaches 4 ohms near 50Hz (Erin), while woofer excursion and bass output were less capable than expected for the cabinet size. A broad 500-700Hz rise and associated lower/female-vocal coloration were audible, and the slightly subdued listening-window treble is necessary to avoid an overly bright in-room balance rather than evidence of ruler-flat axial tuning.
