Short answer: the KEF R3. It ranks #15 of 222 bookshelf speakers by sound quality, rated 4.5/5, at $1,544.56. The Power Sound Audio MT-110-M ranks #63, rated 4.1/5, at $1,350, $194.56 cheaper, a saving that is not big enough to make up the sound-quality gap.
The KEF R3 is the more accurate, deeper-bass pick. A three way bookshelf speaker with KEF’s coaxial driver for stable imaging across seats and very low distortion, easy to run with a modest amp. Its measured preference score, a predictor of how neutral it sounds, is 6.20 against 2.53 for the Power Sound Audio MT-110-M. Its bass reaches about 58Hz before falling 3dB, against 113Hz for the Power Sound Audio MT-110-M. Watch for: The low-frequency alignment rolls gradually rather than delivering high-output sub-bass; KEF specifies 58Hz +/-3dB and Erin’s high-level data supports using an 80Hz subwoofer crossover.
Why pick the Power Sound Audio MT-110-M: A USA made horn tweeter bookshelf speaker with a 10 inch woofer, high sensitivity, and great dynamics without brightness. 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.
Buy the KEF R3. It is rated higher for sound quality, and saving $194.56 with the Power Sound Audio MT-110-M does not make up for the sound-quality gap.

Measured Differences
- Bass depth: the KEF R3 reaches 35.2 Hz (10 dB down) against 68 Hz for the Power Sound Audio MT-110-M, about an octave deeper. Low bass that the other only hints at comes through with real weight.
- Efficiency: the Power Sound Audio MT-110-M is rated at 92.5 dB sensitivity against 86 dB for the KEF R3, so it plays as loud with roughly a third of the amplifier power.
