Short answer: the JTR Noesis 210HT if sound quality matters most, the Klipsch RP-600M II if price matters most. The JTR Noesis 210HT ranks #53 of 130 bookshelf speakers at $1999. The Klipsch RP-600M II ranks #74 at $449.99, $1549.01 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 JTR Noesis 210HT offers: Exceptionally high-output sealed loudspeaker: Erin measured 92.5dB/2.83V/1m sensitivity, less than 3% distortion at both 86dB and 96dB test levels, and excellent compression behavior. The coaxial compression driver and dual 10-inch woofers cross at roughly 850Hz into a nominal 60° x 60° pattern, keeping radiation controlled enough that broad response errors remain amenable to EQ. Its sealed 12dB/octave bass roll-off simplifies subwoofer integration, while Baltic-birch construction and professional-grade drivers suit reference-level cinema use. Watch for: Erin measured F3 at 76Hz and F10 at 43Hz, so the 210HT is designed to hand bass duties to subwoofers rather than operate full-range. The impedance falls to approximately 3 ohms through 100-200Hz (Erin), making a stable separate amplifier preferable. Midrange resonances and the horn-to-woofer directivity transition raise the predicted in-room treble balance; careful toe-in, room treatment and DSP are advisable. Each enclosure is unusually large and heavy for a stand-mount, and the narrow coverage is less forgiving across a wide seating area.
