Short answer: the Aoshida Audio Musician Knight I V2 on measured sound quality, the Klipsch RP-600M II on price. The Aoshida Audio Musician Knight I V2 ranks #73 of 130 bookshelf speakers at $2099. The Klipsch RP-600M II ranks #74 at $449.99, $1649.01 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 Aoshida Audio Musician Knight I V2 offers: A substantial 6.5-inch standmount with unusually high measured sensitivity of 88.7dB. ASR’s Klippel data shows excellent sound-power smoothness of 0.125 and a well-damped bass alignment Q of 0.69, with useful in-room extension estimated at 43Hz. Watch for: The response tilts upward by 0.37dB per octave, so it will sound bright, and predicted in-room smoothness is a poor 0.16. At $2,099/pair it is expensive for a little-known direct-sale brand, and each unusually deep cabinet weighs 35.3 lb.
