Short answer: the Ascend Acoustics ELX Ribbon Tower on measured sound quality, the Polk T50 on price. The Ascend Acoustics ELX Ribbon Tower ranks #6 of 71 floorstanding speakers at $5698. The Polk T50 ranks #55 at $249, $5449 cheaper.
What the Polk T50 offers: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Watch for: 5dB peak at 1khz, 4dB bright top end from 11khz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.
What the Ascend Acoustics ELX Ribbon Tower offers: 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, among the best measured towers in this batch. 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. Watch for: 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 $5,698/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.
Buy the Polk T50 when the price outweighs sound quality for you, and the Ascend Acoustics ELX Ribbon Tower when sound quality outweighs the price instead.
Skip the Polk T50 if sound quality matters to you. It ranks near the bottom of the 71 floorstanding speakers.
