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.

Polk Reserve R100: $699.00 per pair Amazon Polk Audio eBay
Pros: Compact cabinet, unusually useful bass for its size and well-controlled woofer breakup. Erin measured F3/F10 points of 68Hz/49Hz, and the X-Port vent avoids much of the chuffing and pipe resonance common to budget rear ports. The 5.25-inch Turbine Cone woofer and 1-inch Pinnacle ring-radiator tweeter produce good detail at moderate levels, while listening roughly 20° off-axis reduces part of the elevated top octave. Measured bass extension of 68Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Erin measured only about 85dB sensitivity and the impedance reaches 3.6 ohms, so it is neither efficient nor an entirely benign AVR load. The treble runs roughly 3dB above the midrange and becomes aggressive above about 85dB SPL. A directivity discontinuity through the woofer/tweeter crossover means EQ cannot fully repair the power response, and a 400Hz impedance feature plus 500Hz-1kHz response irregularity suggests a cabinet or system resonance. Substantial low-frequency compression at higher playback levels limits clean dynamics.
