Short answer: the Wharfedale Aura 2 for better sound quality, the Ascend Acoustics Sierra-2EX V2 for the lower price. The Wharfedale Aura 2 ranks #13 of 130 bookshelf speakers at $2799. The Ascend Acoustics Sierra-2EX V2 ranks #38 at $1748, $1051 cheaper.
What the Wharfedale Aura 2 offers: Three-way “mini tower” design with a 27x90mm AMT tweeter, 4” mid-range, and 6.5” midwoofer, using an unusual bottom-firing port. Nearly “ruler flat” on-axis linearity (within about 1.5dB for most of the range) apart from one specific breakup point. Exceptional output capability with very low distortion even at high volume - the reviewer reached about 100dB average at 10 feet with no audible strain, outperforming rivals like the KEF LS50 Meta in multitone distortion above 1kHz. Wide horizontal radiation of about ±70° combined with excellent imaging and pair matching - passed demanding stereo-separation test tracks with precise instrument placement. Bass reaches a genuine 40Hz in most rooms, potentially eliminating the need for a subwoofer for material that doesn’t demand extreme sub-bass. About 20dB of usable dynamic range with no compression issues at 96dB/1m. Considered by the reviewer one of the best speakers he’s tested, potentially challenging his personal all-time top five. Watch for: A breakup/peak around 13kHz can sound sharp or shrill depending on the track, the main tonal flaw noted. Minor midbase-to-midrange balance discrepancy (about 1dB), most noticeable if the speaker sits more than about 2 feet from the rear wall. Vertical listening window is narrower than typical, a consequence of the AMT ribbon tweeter’s tall physical size - staying within about ±15-20° of the tweeter reference axis (or slightly below it) is important. Impedance dips to about 3.1 ohms with a 1.4-ohm minimum EPDR, meaning a dedicated amplifier is recommended over an AVR due to potential power-supply strain. Distortion rises at the very lowest frequencies (an expected limitation of a 6.5” woofer), and the woofer audibly struggles with extreme 30-35Hz content at high volume. Horizontal directivity narrows from about ±70° to ±50° above roughly 6-7kHz as the ribbon tweeter’s pattern collapses inward.
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.
