Short answer: the Revel M106, unless the Aura 2 suits your room. The Wharfedale Aura 2 is a three-way mini tower with a 27x90mm AMT tweeter, a 4” mid-range and a 6.5” midwoofer in an unusual bottom-firing port layout, but a breakup peak around 13kHz can sound sharp or shrill depending on the track, the main tonal flaw noted. The M106 is fairly even on-axis with no obvious resonances.
Buy the Wharfedale Aura 2 new; the Revel M106 is no longer sold new, so it only makes sense as a used find.

Newer model: the Revel M126Be, ranked lower, rated 4.3/5.
Pros: CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Predicted in-room response is called “near ideal” by the reviewer, with a smooth downward slope from bass to treble. Distortion at 96dB SPL/1m stays well controlled through the midrange and treble. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Some directivity error and response variation shows up in the crossover region. Horizontal beamwidth of about ±50 degrees is on the narrower side. Vertical directivity requires staying within about ±20 degrees of the reference axis for accurate tonal balance. Minimum impedance dips to 4.6 ohms with several peaks, a moderately demanding load for a compact bookshelf speaker. Discontinued.

Wharfedale Aura 2: $2799 per pair Crutchfield eBay
Pros: 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. Measured bass extension of 56Hz (-3dB), with a measured sensitivity of 87dB.
Cons: 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.
