Short answer: the Power Sound Audio MT-110-M on measured sound quality, the Klipsch RP-600M II on price. The Power Sound Audio MT-110-M ranks #49 of 130 bookshelf speakers at $1350. The Klipsch RP-600M II ranks #74 at $449.99, $900.01 cheaper.
What the Klipsch RP-600M II offers: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original RP-600M. Roughly 10-20° wider horizontal radiation than the original, giving more soundstage envelopment while retaining precise imaging. A major step up in overall tonal neutrality compared to the original RP-600M, largely eliminating that model’s midrange resonance issues. Unusually, sounds better with the grille on - the grille smooths out the elevated treble rather than degrading the sound, a rare trait among speakers the reviewer has tested. More refined back-panel hardware, including anodized binding posts and jumper cables for optional bi-amping. Responds well to EQ correction (verified using measurement software and a miniDSP), letting the on-axis response be made genuinely linear. Watch for: On-axis, the treble runs notably hot - even hotter than the original RP-600M in some respects - and needs about 20° of toe-out or the grille installed to sound balanced. Horizontal dispersion is very slightly less linear across angles than the original RP-600M, a minor trade-off for the wider overall radiation pattern. Klipsch’s marketed sensitivity (about 94.5dB) is, like the original, a half-space rating roughly 9dB above the anechoic reality (closer to 85-86dB). In-room bass rolls off around 60Hz in practice, and a 120Hz boost paired with a midrange scoop gives kick drums their “tambour” without real low-end weight - a subwoofer is still recommended. Vertical listening tolerance is limited to about ±10° from the tweeter axis. Toeing the speaker out for better on-axis tonality (rather than using the grille) introduces slightly more diffuse imaging from added sidewall reflections.
What the Power Sound Audio MT-110-M offers: 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. Watch for: 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.
