#38 Ascend Acoustics Sierra-2EX V2: $1,748 per pair Ascend Acoustics eBay
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.
Cons: 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.
How it compares: Just above it: Selah Audio Integrity - $998 cheaper, 4.5Hz lower bass extension (-3dB). Just below it: Perlisten R5m - $1547 more, 4.2Hz higher bass extension (-3dB).
