Short answer: the Polk Audio XT60. It ranks #177 of 226 floorstanding speakers by sound quality, rated 3.5/5, at $370. The Sony SS-CS3 M2 ranks #209, rated 3.0/5, at $346, $24 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Polk Audio XT60 is the better-sounding option. Passive-radiator-loaded design (6.5” woofer plus two 6.5” passive radiators) gives deeper bass than the driver size alone would suggest: 43.9Hz at -3dB / 38.1Hz at -10dB, genuinely competitive extension for a budget tower. The catch: Bass alignment Q (lfq 0.96) is the highest, least-controlled figure in this entire batch, consistent with owner reports of a slightly loose, boomy low end at higher volumes.
The case for the Sony SS-CS3 M2: The 2025 update of the budget Sony SS-CS3 tower, matching the measured Sony SS-CS5 M2 bookshelf. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sony SS-CS5 M2 and the original Sony SS-CS3, which measured with an uneven balance.
Buy the Polk Audio XT60. It is rated higher for sound quality, and the $24 you would save on the Sony SS-CS3 M2 does not close the gap.
About the ratings: the Sony SS-CS3 M2’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.6 to 3.4, so this verdict could change once it is measured.

Same family: the Polk Audio XT15 (smaller bookshelf, rated 3.7/5), the Polk Monitor XT20 (larger bookshelf, rated 3.4/5), the Polk Audio XT70 (larger floorstanding, ranked higher, rated 3.6/5), the Polk Audio XT30 (smaller center, rated 3.6/5), the Polk Audio XT35 (larger center, rated 4.1/5), the Polk Audio Monitor XT10 (smaller subwoofer, estimated 3.1/5) and the Polk Audio Monitor XT12 (larger subwoofer, estimated 3.3/5). See every Polk Monitor generation.
Pros: Passive-radiator-loaded design (6.5” woofer plus two 6.5” passive radiators) gives deeper bass than the driver size alone would suggest: 43.9Hz at -3dB / 38.1Hz at -10dB, genuinely competitive extension for a budget tower. Hi-Res Audio certified, Dolby Atmos/DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs. Measured bass extension of 43.9Hz (-3dB).
Cons: Bass alignment Q (lfq 0.96) is the highest, least-controlled figure in this entire batch, consistent with owner reports of a slightly loose, boomy low end at higher volumes. On-axis response is also relatively uneven, with narrow-band deviation of about 0.51dB. The vinyl-wrapped (not wood veneer) cabinet reads as budget up close per owner reviews, and at least one owner reported blowing a driver under sustained heavy bass: some caution is warranted with bass-heavy source material at volume.

Sony SS-CS3 M2: $346 per pair Estimated Amazon eBay
Older model: the Sony SS-CS3 (ranked lower, rated 2.8/5). See every Sony SS-CS generation.
Same family: the Sony SS-CS5 M2 (bookshelf, rated 3.2/5) and the Sony SS-CS8 M2 (center, estimated 2.8/5).
Pros: The 2025 update of the budget Sony SS-CS3 tower, matching the measured Sony SS-CS5 M2 bookshelf. It is a 3-way with two 5.12” woofers, a 1” tweeter and a 0.75” super tweeter, rated 45Hz to 50kHz with 88.6dB sensitivity, so an inexpensive receiver drives it easily.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sony SS-CS5 M2 and the original Sony SS-CS3, which measured with an uneven balance. The impedance is 6 ohms and the cabinet is basic vinyl-wrapped MDF.
