Short answer: the Polk Audio Reserve R700 on measured sound quality, the Polk T50 on price. The Polk Audio Reserve R700 ranks #60 of 188 floorstanding speakers, rated 4.3/5, at $2,398. The Polk T50 ranks #126, rated 3.8/5, at $374, $2,024 cheaper.
The Polk Audio Reserve R700 is the more accurate, deeper-bass choice. Three-way design with a 1” ring radiator tweeter, 6.5” mid-range, and dual 8” mid-bass drivers in a ported, down-firing cabinet. Its measured preference score, a predictor of how neutral it sounds, is 6.38 against 4.14 for the Polk T50. Its bass reaches about 40Hz before falling 3dB, against 47Hz for the Polk T50. Watch for: Compression in the high frequencies rises sharply between 96dB and 102dB output: a real limitation only at very high volumes (around 100dB at 3 meters), but a clear step down from pricier ($5,000+) towers.
What the Polk T50 does well: Pretty deep bass for the price. The tradeoff: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.

The Two Speakers In Full
Polk Audio Reserve R700: $2,398 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 R500 (smaller floorstanding, ranked lower, rated 4.2/5), the Polk Reserve R600 (smaller floorstanding, ranked lower, estimated 4.2/5), 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: Three-way design with a 1” ring radiator tweeter, 6.5” mid-range, and dual 8” mid-bass drivers in a ported, down-firing cabinet. On-axis frequency response holds within about ±2dB across most of its range, with genuinely deep bass extension (F3 40Hz) reaching into the mid-30s Hz in-room. Wide horizontal radiation of about ±70°, giving a strong, enveloping stereo width and stage-extension effect on well-recorded tracks. Good low-level dynamics: solid bass thump at quiet listening volumes without over-accentuation. Strong distortion and compression control through the bass and midrange. Real nominal impedance closer to 4 ohms than the marketed 8 ohms, so with the right amplifier it can be driven hard: a $3,000 two-channel integrated brought out significantly more life than a budget $300 unit could. Excellent value at its roughly $1199/pair, ranking among the reviewer’s top picks under $2,500; outperforms the similarly-priced Klipsch RP-8000F II in bass extension and overall smoothness. Measured bass extension of 40Hz (-3dB), with a measured sensitivity of 87.5dB.
Cons: Compression in the high frequencies rises sharply between 96dB and 102dB output: a real limitation only at very high volumes (around 100dB at 3 meters), but a clear step down from pricier ($5,000+) towers. Horizontal directivity mismatch around 4-5kHz, where the tweeter flares wider than the midrange, can sound a bit forward, especially noticeable when toed out further into the room; sidewall absorption or curtains help tame it. Harmonic distortion crosses the reviewer’s 3% threshold around 7kHz at 96dB output, possibly contributing to that same forward quality at high volume. Narrow vertical sweet spot (about ±15° from the tweeter axis), typical of non-coaxial tower designs: more of a consideration for multi-row home theater seating than single-row listening. The ring-radiator tweeter narrows noticeably above about 7-8kHz, and toeing the speaker out more than about 20° causes the top end to fall off quickly. Needs at least 2 feet of clearance from the rear wall to avoid boomy, exaggerated bass, since it lacks the bass-shelf tuning some rivals use to allow closer wall placement. Compared to the pricier KEF R5 Meta, has narrower horizontal (and much narrower vertical) directivity, so seating flexibility is more limited.

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.
