Short answer: the Polk Reserve R500. It ranks #85 of 226 floorstanding speakers by sound quality (rated 4.2/5) at $1,118 and is still sold new; the Sony SS-CS3 ranks #213 (rated 2.8/5) and is discontinued, so it is only an option used. The Sony SS-CS3’s replacement, the Sony SS-CS3 M2, is rated 3.0/5.
The Polk Reserve R500 is the more accurate, deeper-bass choice. 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 4.11 for the Sony SS-CS3. Its bass reaches about 51Hz before falling 3dB, against 72Hz for the Sony SS-CS3. The tradeoff: A bump around 4-6kHz gives a “shouty,” mildly sibilant quality in the lower treble.
The case for the Sony SS-CS3: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. Watch for: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments.
Buy the Polk Reserve R500. It is rated higher for sound quality, and the Sony SS-CS3 is discontinued, so it is only available used.

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 Polk 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.

Sony SS-CS3: $450 per pair Discontinued eBay
Newer model: the Sony SS-CS3 M2, ranked higher, estimated 3/5.
Same family: the Sony SS-CS5 (bookshelf, rated 3.5/5).
Pros: Affordable entry-level floorstanding tower offering solid sensitivity (88.6dB SPL at 2.83V/1m), making it easy to power with standard budget AVRs. Harmonic distortion remains reasonably low at moderate listening levels (86dB SPL) when high-pass filtered above 80-100Hz with a dedicated subwoofer. Front-ported design allows relatively close placement to front boundaries without excessive port occlusion. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 88.6dB.
Cons: Severe cabinet and driver resonances plague the passband between 100Hz and 600Hz, imparting audible coloration and chesty resonances to male vocals and acoustic instruments. Irregular frequency response peaks and dips make automated receiver room correction difficult to equalize effectively. Poor low-frequency extension (F3 of 72Hz, F10 of 39Hz) for a floorstander, combined with rapid distortion escalation below 80Hz at higher SPLs (96dB+). Supertweeter driver adds crossover complexity without providing audible high-frequency benefit within the human hearing spectrum. Discontinued.
