#30 Polk Reserve R500: $699.00 Amazon eBay

Pros: Dual 5.25” midwoofers paired with a ring radiator tweeter in a floorstanding tower design. Surprisingly neutral overall compared to Polk’s smaller bookshelf models - notably more even-handed than the brighter-sounding R200 the reviewer tested previously. Good linearity on-axis, within about -3/+2dB. Sensitivity close to 86dB, easily driven to adequate levels in a small-to-medium room with a 100W-capable amplifier. Takes very well to EQ - a single band of correction (about a 2dB cut around 4-5kHz) resolves the main tonal issue and transforms the sound. Dynamic range and compression performance is solidly “medium,” holding up fine through about 20dB of level increase before higher-frequency and bass output start to taper at extreme volumes.

Cons: A bump around 4-6kHz gives a “shouty,” mildly sibilant quality in the lower treble. Counterintuitively, toeing the speaker out to reduce brightness makes this worse rather than better, since the ring-radiator tweeter’s directivity narrows rapidly above about 6-7kHz - pointed on-axis retains enough top-end air to balance the bump, but toed away that air drops off and the shoutiness stands out more. Bass is adequate for its 5.25” woofers but lacks real weight below about 40-50Hz; a subwoofer is still needed for movies and bass-heavy music. A cabinet resonance around 160-170Hz subtracts from rather than adds boom to the mid-bass region. Vertical listening window is fairly narrow - sitting more than about 10-20° above or below the tweeter axis causes a suckout in the 2-5kHz range, reducing clarity and attack. Multitone distortion ramps up noticeably around 1kHz, and crossing over to a subwoofer at 80Hz doesn’t meaningfully reduce it - likely a surround-related effect rather than excursion-related. Without applying corrective EQ, the reviewer says the 4-6kHz brightness would make it harder to live with day to day.

How it compares: Just above it: ELAC Debut 3.0 DF63 - $50 cheaper, 0.4Hz higher bass extension (-3dB). Just below it: Linkwitz Lab LXmini - $194 cheaper, 1.2Hz lower bass extension (-3dB).
