Polk R200: $799.00 per pair Amazon eBay
Pros: Two-way design with a 6.5” midwoofer and 1” ring radiator tweeter, giving reasonably tight, well-defined imaging. Neutral through most of the midrange (roughly 200Hz-1kHz). On-axis response holds within about 1.5dB up to 10kHz. About 20dB of usable dynamic range (76dB to 96dB) before more significant compression sets in. Reasonably close to a 4-ohm nominal load, giving some flexibility with amplifier choice, though a dedicated 4-ohm-capable amp is still recommended. Measured bass extension of 74Hz (-3dB).
Cons: A resonance and associated distortion increase around 800Hz-1kHz creates a “tinny,” occasionally glaring quality on certain instruments and vocals, confirmed both by ear and in the frequency-response and distortion measurements. Above about 10kHz, the ring-radiator tweeter takes on an artificial, “digital-esque” quality, then falls off quickly above 16kHz. F3 of 74Hz and F10 of 50Hz mean there’s essentially no meaningful bass “thump” below about 60Hz: a subwoofer is strongly recommended even just to restore basic kick-drum presence. The ring radiator tweeter’s dispersion narrows sharply above about 8kHz, so the speaker should be aimed close to on-axis (no more than 5-10° of toe-out). Vertical listening position is fairly critical: moving more than a few degrees above or below the tweeter line causes a noticeable timbre shift due to a gap in the crossover region. Multitone distortion spikes substantially (to around 10%) in the 600Hz-1kHz region at higher output levels (around 96dB/1m), meaning the glare gets worse the louder it’s played. At the highest tested output (102dB, 26dB of dynamic range), the woofer shows clear signs of struggling; crossing to a subwoofer around 80-100Hz helps prevent bottoming out but doesn’t fully eliminate the compression.

Klipsch RP-600M: $377.99 per pair Discontinued Amazon eBay
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.
