Short answer: the Rockville RockTower 68B, though neither ranks well in its class. It ranks #221 of 226 floorstanding speakers by sound quality, rated 2.2/5, at $234.90; the Klipsch Reference R-600F ranks #226, rated 1.8/5, and costs $759.98, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 226 floorstanding speakers, so if sound quality matters, consider the Revel Concerta2 F35 instead, ranked #31 at $900.
The Rockville RockTower 68B is the better-sounding choice. An unusually inexpensive current 3-way tower with dual 6.5-inch woofers, a dedicated 6.5-inch midrange and silk-dome tweeter. The tradeoff: 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.
Why pick the Klipsch Reference R-600F: Next-generation floorstanding speaker featuring dual 6.5-inch spun-copper TCP woofers and a 1-inch aluminum LTS tweeter mated to a larger 90x90 edge-to-edge Tractrix horn for wider bandwidth and directivity control. The catch: Two-way crossover design with dual 6.5-inch woofers playing into the midrange horn can lead to vertical lobing off-axis.
Buy the Rockville RockTower 68B. It is rated higher for sound quality than the Klipsch Reference R-600F and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Worth knowing: the Klipsch Reference R-600F has not been measured yet. Its rating is estimated from related models, with a likely range of 1.6 to 2.0, so treat this verdict as provisional.

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.

Same family: the Klipsch Reference R-40M (smaller bookshelf, estimated 1.4/5), the Klipsch Reference R-50M (larger bookshelf, estimated 1.7/5), the Klipsch Reference R-800F (larger floorstanding, ranked higher, estimated 1.9/5), the Klipsch Reference R-30C (smaller center, estimated 3.4/5) and the Klipsch Reference R-50C (larger center, estimated 3.5/5). See every Klipsch Reference generation.
Pros: Next-generation floorstanding speaker featuring dual 6.5-inch spun-copper TCP woofers and a 1-inch aluminum LTS tweeter mated to a larger 90x90 edge-to-edge Tractrix horn for wider bandwidth and directivity control. High sensitivity of 96dB (2.83V @ 1m) and 100W continuous / 400W peak power handling allow it to achieve high output with modest amplification. Rear Tractrix port tuning achieves a specified frequency response of 38Hz to 21kHz (+/- 3dB). Hidden Dolby Atmos terminals on the rear simplify add-on height module wiring.
Cons: Two-way crossover design with dual 6.5-inch woofers playing into the midrange horn can lead to vertical lobing off-axis. Standardized Klippel NFS Spinorama preference scores have not yet been published to verify linearity.
