Short answer: the Ascend Acoustics ELX Ribbon Tower if sound quality matters most, the JBL Stage 2 280F if price matters most. The Ascend Acoustics ELX Ribbon Tower ranks #6 of 71 floorstanding speakers at $5698. The JBL Stage 2 280F ranks #62 at $529.95, $5168.05 cheaper.
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.
What the JBL Stage 2 280F offers: Genuinely impressive output capability and low compression/distortion for the price, courtesy of the dual 8” woofers - the reviewer’s standout praise for this pair. High sensitivity (89.5dB measured) and low impedance make it easy to drive. Decent bass extension (F3 48Hz, F10 30Hz) reaches about 50Hz in-room. Horizontal dispersion is reasonably consistent (~55 degrees), meaning the speaker takes reasonably well to EQ correction. Watch for: Explicitly called out as disappointing relative to expectations for the JBL name and this price point - lacks native linearity compared to similarly-priced alternatives like the Polk Reserve R500, which the reviewer recommends instead for anyone who doesn’t want to rely on EQ. Treble falls off a cliff above about 10-12kHz, giving a notable lack of air/space that needs real correction (a wide +Q0.5 boost from 10-20kHz) to fix. A sharp impedance resonance around 900Hz-1.1kHz is nearly impossible to EQ out cleanly even with narrow filters. Elevated multitone distortion in the 600Hz-2.5kHz range, tied to the midwoofer rather than the tweeter. Compared to the similarly-priced Klipsch RP-6000F II/RP-8000F II, this JBL is less directive and native-flat but does extend roughly 20Hz deeper in the bass - a real tradeoff either way, not a clean win.
Buy the Ascend Acoustics ELX Ribbon Tower if sound quality is the priority over the price, or the JBL Stage 2 280F if the price is the priority over sound quality.
Skip the JBL Stage 2 280F if sound quality matters to you. It ranks near the bottom of the 71 floorstanding speakers.
