Newer model: the Klipsch RP-600M II, ranked higher, rated 3.7/5.

Pros: More linear horizontal dispersion than the updated RP-600M II: as you move side-to-side, the tonal character changes less, a genuine advantage for off-axis listening consistency. Takes exceptionally well to EQ correction (miniDSP or similar), letting a knowledgeable owner fix its tonal shortcomings without needing to upgrade. Standard 6.5” woofer/horn-tweeter two-way design with reasonably gradual bass rolloff (F3 ~70Hz, F10 ~40Hz) rather than a steep vented-enclosure cutoff. Measured bass extension of 73Hz (-3dB), with a measured sensitivity of 85.2dB.

Cons: A strong, annoying resonance in the lower vocal range around 300Hz stands out clearly (though it can be EQ’d out). Overall tonal balance is notably less neutral than the newer RP-600M II, with a roughly 3-4dB suckout in the estimated in-room response. The waveguide doesn’t extend flush to the baffle edge, increasing diffraction compared to the redesigned version. Klipsch’s marketed sensitivity spec (about 96dB) is a half-space, in-room-style rating roughly 9dB above the true anechoic figure (closer to 85-86dB), which can mislead buyers comparing spec sheets. Elevated treble on-axis, similar to its successor, benefits from toe-out or careful placement. Vertical listening tolerance is limited to about ±10° from the tweeter axis. Still needs a subwoofer for real bass weight; a boost around 120Hz gives kick drums their “tambour” without the underlying “meat.”. Discontinued.
