Short answer: the Ascend Acoustics Sierra-LX. Both are rated 4.3/5 for sound quality (#37 and #41 of 222 bookshelf speakers), and the Ascend Acoustics Sierra-LX costs $1,598 against $1,748 for the Ascend Acoustics Sierra-2EX V2, and with sound quality even, the cheaper one is the better buy.
The Ascend Acoustics Sierra-LX is the more accurate, deeper-bass choice. A compact bookshelf speaker with very neutral, flat sound, a wide soundstage, and surprisingly deep bass in a bamboo cabinet. Its measured preference score, a predictor of how neutral it sounds, is 6.63 against 5.88 for the Ascend Acoustics Sierra-2EX V2. Its bass reaches about 47Hz before falling 3dB, against 58.6Hz for the Ascend Acoustics Sierra-2EX V2. Watch for: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels.
What the Ascend Acoustics Sierra-2EX V2 does well: A ribbon tweeter bookshelf speaker with hand matched pairs, a frequency response printout for each unit, and a long seven year warranty. The tradeoff: On-axis response is relatively uneven, with an average deviation of about 0.45dB, so a listener sitting dead center may notice more unevenness than with smoother AsciLab or Ascend towers.
Buy the Ascend Acoustics Sierra-LX. Both are rated the same for sound quality, and it costs $150 less than the Ascend Acoustics Sierra-2EX V2.
