Short answer: the Ascend Acoustics ELX Ribbon Tower on measured sound quality, the Dynaudio Emit 30 on price. The Ascend Acoustics ELX Ribbon Tower ranks #12 of 228 floorstanding speakers, rated 4.6/5, at $5,698. The Dynaudio Emit 30 ranks #139, rated 3.9/5, at $1,274.25, $4,423.75 cheaper.
The Ascend Acoustics ELX Ribbon Tower is the more accurate, deeper-bass choice. 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 3.84 for the Dynaudio Emit 30. Its bass reaches about 38.7Hz before falling 3dB, against 44Hz for the Dynaudio Emit 30. 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 Dynaudio Emit 30: A slim tower with surprisingly deep bass for its price, low distortion, and even sound that responds well to EQ. The catch: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven (sometimes soft, sometimes forward) depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result.
Buy the Ascend Acoustics ELX Ribbon Tower when sound quality outweighs the price for you, and the Dynaudio Emit 30 when the price outweighs sound quality instead.
