Short answer: the Polk Reserve R500 for better sound quality, the Polk T50 for the lower price. The Polk Reserve R500 ranks #74 of 188 floorstanding speakers, rated 4.2/5, at $1,118. The Polk T50 ranks #126, rated 3.8/5, at $374, $744 cheaper.
The case for the Polk T50: Pretty deep bass for the price. The tradeoff: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
The Polk Reserve R500 is the more accurate pick. Dual 5.25” midwoofers paired with a ring radiator tweeter in a floorstanding tower design. Its measured preference score, a predictor of how neutral it sounds, is 5.86 against 4.14 for the Polk T50. Watch for: A bump around 4-6kHz gives a “shouty,” mildly sibilant quality in the lower treble.
Buy the Polk T50 when the price outweighs sound quality for you, and the Polk Reserve R500 when sound quality outweighs the price instead.

Polk T50: $374 per pair Amazon eBay
Same family: the Polk T15 (bookshelf, rated 1.9/5).
Pros: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.

Polk Reserve R500: $1,118 per pair Amazon eBay
Same family: the Polk Reserve R100 (smaller bookshelf, rated 3.4/5), the Polk R200 (larger bookshelf, rated 3.2/5), the Polk Reserve R600 (larger floorstanding, ranked lower, estimated 4.2/5), the Polk Audio Reserve R700 (larger floorstanding, ranked higher, 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: 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. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 86.2dB.
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.
