Short answer: the Polk T50. Both are rated 3.8/5 for sound quality (#152 and #153 of 228 floorstanding speakers), and the Polk T50 costs $498 against $11,090 for the Vandersteen Treo CT, so with nothing between them on sound quality, price settles it.
The Vandersteen Treo CT is the more accurate choice. A time-aligned four-driver tower with exceptionally deep bass and smooth sound spread through the room. Its measured preference score, a predictor of how neutral it sounds, is 4.95 against 4.14 for the Polk T50. The catch: At $11090 per pair, 80 lbs (36.3 kg) each and only 85dB sensitivity, it is costly and amplifier-demanding.
The case for the Polk T50: A budget tower with twin woofers and passive radiators that gives pretty deep bass for very little money. Watch for: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
Buy the Polk T50. Both are rated the same for sound quality, and it costs $10,592 less than the Vandersteen Treo CT.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
