Yamaha NS-800A: $4,999.90 per pair The Music Room eBay
Pros: Exceptionally well-built cabinet with no internal resonance issues at all: confirmed clean in both burst decay and impedance measurements. Good, wide directivity (~75 degrees horizontal) that stays consistent enough to EQ successfully. Distortion is low, staying under 3% at 96dB, and dynamic range holds up well until right near its 102dB limit. A shallower, higher-frequency bass rolloff profile (F3 68Hz, F10 35Hz) means it can be placed closer to the wall (about a foot) without turning boomy, actually gaining bass presence rather than losing it. Measured bass extension of 68Hz (-3dB), with a measured sensitivity of 84.9dB.
Cons: A wide, roughly 2kHz-10kHz scoop in the upper-midrange/lower-treble gives it a laidback, soft, low-attack character: notably worse than the reviewer’s Audio First Fidelia reference in an A/B comparison. On top of that, treble breaks up badly above 10kHz, swinging up as much as 8dB: a significant, named flaw. Sounds inconsistently voiced as a result (bright on some material like cymbals and shakers, dull/laidback on vocals and instrument attack) until corrected with real parametric EQ (the reviewer needed a +2dB boost around 4.5kHz at Q0.5 plus taming the treble spike to bring it to life) combined with near-wall placement and 30-degree toe-out. Without that combination, it’s a tough sale for a $5000 bookshelf speaker.

Klipsch RP-600M II: $449.99 per pair Amazon eBay
Older model: the Klipsch RP-600M (ranked lower, rated 2.9/5).
Pros: 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. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 86dB.
Cons: 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.
