Short answer: the Polk Signature Elite ES60. It ranks #62 of 73 floorstanding speakers by sound quality, rated 3.4/5, at $599. The Rockville RockTower 68B ranks #72, rated 2.2/5, at $234.90, $364.10 cheaper, which does not close the gap in sound quality.
The case for the Polk Signature Elite ES60: Three 6.5-inch woofers deliver strong output, 39Hz measured extension and about 89.5dB measured sensitivity. Watch for: The measured data show enough directivity and response unevenness to keep it below the strongest neutral towers, and its large cabinet needs room.
What the Rockville RockTower 68B does well: An unusually inexpensive current 3-way tower with dual 6.5-inch woofers, a dedicated 6.5-inch midrange and silk-dome tweeter. The catch: Objective performance is weak: its preference score is only 0.96 without a subwoofer and 3.42 with one, placing it near the bottom of the measured floorstanders.
Buy the Polk Signature Elite ES60. It is rated higher for sound quality, and saving $364.10 with the Rockville RockTower 68B does not make up for the sound-quality gap.

Polk Signature Elite ES60: $599 per pair Crutchfield eBay
Pros: Three 6.5-inch woofers deliver strong output, 39Hz measured extension and about 89.5dB measured sensitivity. Its local Spinorama scores of 3.69 raw and 5.57 with subwoofer are respectable for a large value-oriented tower, with reasonably smooth listening-window behavior. Measured bass extension of 51.3Hz (-3dB), with a measured sensitivity of 90dB.
Cons: The measured data show enough directivity and response unevenness to keep it below the strongest neutral towers, and its large cabinet needs room. Polk’s 32Hz lower-limit claim is optimistic relative to the independent anechoic result.

Rockville RockTower 68B: $234.90 per pair Amazon Rockville eBay
Pros: An unusually inexpensive current 3-way tower with dual 6.5-inch woofers, a dedicated 6.5-inch midrange and silk-dome tweeter. Erin’s high-quality Spinorama data measures useful 54Hz extension, and the manufacturer sells each tower directly with free shipping. Measured bass extension of 60.1Hz (-3dB).
Cons: Objective performance is weak: its preference score is only 0.96 without a subwoofer and 3.42 with one, placing it near the bottom of the measured floorstanders. The large cabinet is lightly priced and specified sensitivity is only 87dB despite the multi-driver layout.
