#7 Ascend Acoustics ELX Ribbon Tower: $5,698 per pair Ascend Acoustics eBay

Pros: A RAAL 70-20xram ribbon tweeter and dual SEAS Excel aluminum woofers in a 3-way, 4-driver bamboo tower measure a genuine 38.7Hz extension point with a nearly flat on axis slope of 0.05dB per octave, one of the flattest measured towers we list. The bass alignment Q of 0.62 keeps the low end well damped rather than peaky. Backed by a 7 year parts and labor warranty and hand assembled in Orange County, California, with each pair matched within +/-1.5dB. Measured bass extension of 38.7Hz (-3dB).

Cons: Listening window smoothness measures a moderate 0.40 and on axis deviation runs 0.286dB average, both trailing the tighter figures posted by some of the passive AsciLab and Ascend bookshelf models in this same batch. At $5698/pair it is Ascend’s most expensive tower, well above the Titan dome tweeter version of the same cabinet. The manufacturer’s own claimed sensitivity (87.5dB) runs nearly 1.5dB higher than the independently measured average (86.1dB), worth accounting for when matching an amplifier.

How it compares: Just above it: Radiant Acoustics Clarity 66 - $2300 more, 1.6Hz lower bass extension (-3dB). Just below it: Magico S5 2024 - $35302 more, 0.5Hz higher bass extension (-3dB).
