Short answer: the KEF R3 Meta. It ranks #10 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99. The Power Sound Audio MT-110-M ranks #63, rated 4.1/5, at $1,350, $1,149.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The KEF R3 Meta is the more accurate, deeper-bass option. A three way bookshelf speaker with KEF’s coaxial driver, superb accuracy that holds across the room, and bass that reaches deep for its size. Its measured preference score, a predictor of how neutral it sounds, is 6.10 against 2.53 for the Power Sound Audio MT-110-M. Its bass reaches about 76Hz before falling 3dB, against 113Hz for the Power Sound Audio MT-110-M. The catch: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it.
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 Meta. It is rated higher for sound quality, and the $1,149.99 you would save on the Power Sound Audio MT-110-M does not close the gap.

Measured Differences
- Bass depth: the KEF R3 Meta reaches 37 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.
- Tonal accuracy above the bass: with a subwoofer taking the low end, the KEF R3 Meta scores 7.9 against 5.9 for the Power Sound Audio MT-110-M on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
- Efficiency: the Power Sound Audio MT-110-M is rated at 92.5 dB sensitivity against 85.9 dB for the KEF R3 Meta, so it plays as loud with roughly a third of the amplifier power.
