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 #12 of 228 floorstanding speakers, rated 4.6/5, at $5,698. The JBL Stage 2 280F ranks #188, rated 3.4/5, at $1,059.90, $4,638.10 cheaper.
The Ascend Acoustics ELX Ribbon Tower is the more accurate, deeper-bass choice. A 3-way bamboo tower with a RAAL ribbon tweeter that measures a 6.97 preference score, bass to 38.7Hz and a nearly flat on-axis response. Its measured preference score, a predictor of how neutral it sounds, is 6.97 against 4.69 for the JBL Stage 2 280F. Its bass reaches about 38.7Hz before falling 3dB, against 48Hz for the JBL Stage 2 280F. The tradeoff: 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.
Why pick the JBL Stage 2 280F: 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. The tradeoff: 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.
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.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
