Short answer: the Ascend Acoustics Sierra-LX. Both are rated 4.3/5 for sound quality (#37 and #42 of 216 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. Very neutral, flat frequency response: within about plus or minus 1.5dB ignoring one narrow dip. 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 RAAL true ribbon tweeter is paired with a custom SEAS Excel Curv woofer, with the crossover optimized against Klippel NFS measurement data. 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.

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.

Same family: the Ascend Acoustics Sierra 1 v2 (smaller bookshelf, rated 4.7/5), the Ascend Acoustics Sierra-2EX V2 (smaller bookshelf, ranked lower, rated 4.3/5), the Ascend Acoustics Sierra Titan Tower (floorstanding, rated 4.4/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5). See every Ascend Sierra generation.
Pros: Very neutral, flat frequency response: within about plus or minus 1.5dB ignoring one narrow dip. Bass extension down to about 40Hz in-room despite the compact size. Wide, well-balanced soundstage (~60 degrees). Solid build quality with a laminated bamboo cabinet. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 81dB.
Cons: Very low sensitivity at about 81dB, so it needs a genuinely powerful amplifier to reach normal listening levels. Noticeable midrange distortion becomes audible above about 82-83dB SPL. A narrow dip around 3.5kHz on-axis in larger rooms without sidewall reflections: toeing the speakers out 10-20 degrees fills it in, but adds some brightness to the treble. Sensitive to listening height: sitting even slightly above or below tweeter level noticeably shifts the tonal balance.

Ascend Acoustics Sierra-2EX V2: $1,748 per pair Ascend Acoustics $1,748 eBay
Older model: the Ascend Acoustics Sierra 2 (ranked lower, rated 3.7/5). See every Ascend Sierra generation.
Same family: the Ascend Acoustics Sierra 1 v2 (smaller bookshelf, rated 4.7/5), the Ascend Acoustics Sierra-LX (larger bookshelf, ranked higher, rated 4.3/5), the Ascend Acoustics Sierra Titan Tower (floorstanding, rated 4.4/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5).
Pros: A RAAL true ribbon tweeter is paired with a custom SEAS Excel Curv woofer, with the crossover optimized against Klippel NFS measurement data. Listening window smoothness measures 0.45, a moderate but usable figure for a compact standmount. Pairs are hand matched within +/-1.5dB and shipped with their own individual frequency response printout, backed by a 7 year parts and labor warranty from direct USA assembly in Orange County, California. Measured bass extension of 58.6Hz (-3dB).
Cons: 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. Bass extension is modest for the price class at a measured 51.3Hz at -6dB. Ascend sells direct only, with no dealer network or third party retailers for an in person audition.
