Short answer: the Ascend Acoustics ELX Ribbon Tower on measured sound quality, the Klipsch RP-6000F II on price. The Ascend Acoustics ELX Ribbon Tower ranks #12 of 228 floorstanding speakers, rated 4.6/5, at $5,698. The Klipsch RP-6000F II ranks #140, rated 3.9/5, at $999.98, $4,698.02 cheaper.
Why pick the Klipsch RP-6000F II: An affordable horn tower that handles lots of power cleanly, with precise imaging for home theater. The tradeoff: Worse baffle-step coloration than the smaller Klipsch RP-5000F II (3-4dB swing vs 2dB), plus a sibilance issue the 5000F doesn’t have: a real regression in tonal balance despite the higher price.
The Ascend Acoustics ELX Ribbon Tower is the more accurate, deeper-bass option. Highly accurate three way bamboo towers with a ribbon tweeter, deep tight bass and a long warranty. Its measured preference score, a predictor of how neutral it sounds, is 6.97 against 5.74 for the Klipsch RP-6000F II. Its bass reaches about 38.7Hz before falling 3dB, against 67Hz for the Klipsch RP-6000F II. The catch: Listening window smoothness measures a moderate 0.40 and on axis deviation runs 0.286dB average, both trailing the tighter figures posted by some smaller passive AsciLab and Ascend bookshelf models.
Buy the Klipsch RP-6000F II if the price is the priority over sound quality, or the Ascend Acoustics ELX Ribbon Tower if sound quality is the priority over the price.
