Short answer: the Ascend Acoustics ELX Ribbon Tower if sound quality matters most, the ELAC Debut 3.0 DF63 if price matters most. The Ascend Acoustics ELX Ribbon Tower ranks #12 of 228 floorstanding speakers, rated 4.6/5, at $5,698. The ELAC Debut 3.0 DF63 ranks #84, rated 4.2/5, at $1,298, $4,400 cheaper.
The Ascend Acoustics ELX Ribbon Tower is the more accurate, deeper-bass pick. Highly accurate three way bamboo towers with a ribbon tweeter, deep tight bass and a long warranty. Its measured preference score, a predictor of how neutral it sounds, is 6.97 against 5.83 for the ELAC Debut 3.0 DF63. Its bass reaches about 38.7Hz before falling 3dB, against 71Hz for the ELAC Debut 3.0 DF63. 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 smaller passive AsciLab and Ascend bookshelf models.
What the ELAC Debut 3.0 DF63 does well: Affordable three way floorstanding speakers with a dedicated midrange, low distortion when played loud and good dispersion for the money. Watch for: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals.
Buy the Ascend Acoustics ELX Ribbon Tower when sound quality outweighs the price for you, and the ELAC Debut 3.0 DF63 when the price outweighs sound quality instead.
