Short answer: the Wharfedale Aura 2 on measured sound quality, the Ascend Acoustics CMT-340 SE2 on price. The Wharfedale Aura 2 ranks #13 of 130 bookshelf speakers at $2799. The Ascend Acoustics CMT-340 SE2 ranks #23 at $798, $2001 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 CMT-340 SE2 offers: High-quality manufacturer Klippel NFS data shows 0.295dB on-axis average absolute deviation, 0.531 listening-window smoothness, and a strong 7.17 preference score with a subwoofer. Its dual 6.5-inch woofers, 92dB anechoic sensitivity, and 240W continuous power rating support high output and dynamics. Watch for: Bass rolls off early for the cabinet size, measuring 77.6Hz at -3dB, 64.5Hz at -6dB, and 48.3Hz at -12dB; the preference score without a subwoofer is only 4.51. The 4.35 sound-power directivity-index standard deviation also indicates more off-axis variation than the strongest designs, and the rear port needs placement clearance.
