Short answer: the Ascend Acoustics Sierra 1 v2. It ranks #3 of 179 bookshelf speakers by sound quality (rated 4.7/5); the Aalto Speakers Aalto 1 EVO ranks #11 (rated 4.3/5).
The Ascend Acoustics Sierra 1 v2 is the more accurate, deeper-bass pick. An extremely accurate bookshelf speaker, with a bamboo cabinet, wide even dispersion and clean output when played loud. Its measured preference score, a predictor of how neutral it sounds, is 6.65 against 5.92 for the Aalto Speakers Aalto 1 EVO. Its bass reaches about 39Hz before falling 10dB, against 47.4Hz for the Aalto Speakers Aalto 1 EVO. The tradeoff: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material.
The case for the Aalto Speakers Aalto 1 EVO: A very compact Finnish bookshelf speaker with excellent, neutral sound and a waveguided tweeter at a budget price. The catch: Low 81.5dB sensitivity and a 3.3-ohm minimum impedance demand a capable amplifier.
