#2 Ascend Acoustics ELX Ribbon Horizon: $3,098 each Ascend Acoustics eBay
Pros: A RAAL true ribbon tweeter and a 6” SEAS Curv midrange in its own sealed chamber sit between two 6” long-throw SEAS woofers in a laminated bamboo cabinet. Ascend’s Klippel near-field measurements show the lowest on-axis deviation of any center channel ranked here (0.15) and a listening window within 1.9dB from 300Hz to 5kHz, and its preference score of 6.17 without a subwoofer is second only to Perlisten’s S7c. Bass is among the deepest of any center here, reaching 51.3Hz (-3dB) and about 30Hz (-10dB), so it can play full range in most rooms. Dispersion is wide horizontally (about ±60 degrees), which keeps dialogue consistent for off-center seats.
Cons: The measurements come from Ascend itself, not an independent reviewer. The ribbon’s vertical dispersion is narrow (about ±25 degrees), so aim the tweeter at ear height rather than tilting it from far above or below the screen. It is sold only direct from Ascend, and at 584mm wide and 52 lb it needs a deep, sturdy shelf.
How it compares: Just above it: Perlisten S7c - $5697 more, 4Hz higher bass extension (-3dB). Just below it: Perlisten R5c - $103 cheaper, 0.6Hz higher bass extension (-3dB).
