Short answer: the Ascend Acoustics Sierra-LX. It ranks #33 of 130 bookshelf speakers by sound quality at $1598; the Ascend Acoustics Sierra-2EX V2 ranks #38 and costs $1748, which makes this an easy call rather than a real tradeoff.
What the Ascend Acoustics Sierra-LX offers: 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. Watch for: 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.
What the Ascend Acoustics Sierra-2EX V2 offers: 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. Watch for: On axis deviation (measured average absolute deviation 0.454) is the roughest of any speaker in this batch, meaning a listener sitting dead center may notice more on axis unevenness than the smoother AsciLab or Ascend tower models nearby. 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.
Buy the Ascend Acoustics Sierra-LX. It ranks higher for sound quality than the Ascend Acoustics Sierra-2EX V2 and costs less, so there is no real case for the other one.
