Short answer: the Ascend Acoustics Sierra-2EX V2 on measured sound quality, the ELAC DBR62 on price. The Ascend Acoustics Sierra-2EX V2 ranks #38 of 130 bookshelf speakers at $1748. The ELAC DBR62 ranks #55 at $799, $949 cheaper.
What the ELAC DBR62 offers: Two-way design with a 6.5” woofer and 1” dome tweeter in a shallow waveguide, with the tweeter positioned close to the woofer for near-point-source coherence - giving more vertical listening leeway than typical two-ways. Notably forgiving of placement and aiming: sounds good from directly on-axis all the way to 30° of toe-out (parallel with the rear wall), making it more room-independent than many speakers this price. Wide horizontal radiation of about ±70° until the tweeter starts beaming, right in the reviewer’s preferred sweet spot. A mild, wide-Q bass bump centered around 100Hz adds a bit of extra punch that the reviewer personally likes. On-axis linearity within about ±2.5dB, with a strong measured preference score of 5.3. Distortion stays below 3% at both 86dB and 96dB until around 50Hz. Vertical sweet spot of about ±10-20° works well for multi-row home theater seating. The reviewer calls it “the epitome of a good speaker” for its price, with no reservations recommending it. Watch for: A slight recess in the 1-2kHz region reduces vocal presence somewhat compared to other speakers in direct comparison. A mild hot spot around 4-5kHz can read as slight sibilance when pointed directly on-axis. Low-to-mid sensitivity (about 84.3dB) combined with a current draw that behaves like roughly 2.4 ohms between 100-200Hz means it’s best driven by a dedicated 4-ohm-capable amplifier rather than an AVR. A diffraction dip from the baffle edge is visible in measurements - typical of any standard rectangular-baffle speaker and not correctable without a much more expensive curved-baffle design. Multitone distortion testing suggests some potential midrange distortion could be audible on certain material, though the reviewer didn’t personally notice it. Minor resonances appear around 700Hz and 1-1.5kHz, possibly tied to the enclosure, port, or cone/surround edge termination, though their audible impact appears minimal. F3 of 53Hz means a subwoofer is still needed for real bass extension below about 40Hz.
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.
