Same family: the Polk R200 (larger bookshelf, ranked lower, rated 3.2/5), the Polk Reserve R500 (smallest floorstanding, rated 4.2/5), the Polk Reserve R600 (floorstanding, estimated 4.2/5), the Polk Audio Reserve R700 (largest floorstanding, rated 4.3/5), the Polk Audio Reserve R300 (smallest center, estimated 3.6/5), the Polk Audio Reserve R350 (center, rated 3.7/5) and the Polk Audio Reserve R400 (largest center, estimated 3.8/5).
Pros: Compact bookshelf speakers with unusually useful bass for their size and a vent that avoids port noise. 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.
