Short answer: the Wharfedale Aura 2. It ranks #13 of 214 bookshelf speakers by sound quality, rated 4.6/5, at $2,799; the Revel Performa4 M146 ranks #22, rated 4.5/5, and costs $2,999.95, so there is not much of a tradeoff to weigh.
What the Wharfedale Aura 2 does well: Three-way “mini tower” design with a 27x90mm AMT tweeter, 4” mid-range, and 6.5” midwoofer, using an unusual bottom-firing port. The catch: A breakup/peak around 13kHz can sound sharp or shrill depending on the track, the main tonal flaw noted.
What the Revel Performa4 M146 does well: The larger Performa4 standmount, pairing a 6.5” ceramic composite woofer with a 1” ceramic dome tweeter in Revel’s seventh generation Acoustic Lens waveguide, crossed over at 1.7kHz. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Revel M106.
Buy the Wharfedale Aura 2. It is rated higher for sound quality than the Revel Performa4 M146 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: the Revel Performa4 M146’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.1 to 4.8, so this verdict could change once it is measured.

The Two Speakers In Full
Wharfedale Aura 2: $2799 per pair Crutchfield eBay
Same family: the Wharfedale Aura 1 (smaller bookshelf, estimated 4.2/5), the Wharfedale Aura 3 (smaller floorstanding, estimated 4.6/5), the Wharfedale Aura 4 (larger floorstanding, estimated 4.7/5), the Wharfedale Aura CS (smaller center, estimated 3.6/5) and the Wharfedale Aura C (larger center, estimated 4.1/5).
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.

Revel Performa4 M146: $2,999.95 per pair Estimated Audio Advice eBay
Same family: the Revel Performa4 M145 (smaller bookshelf, estimated 4.3/5), the Revel Performa4 F345 (smaller floorstanding, estimated 4.4/5), the Revel Performa4 F346 (larger floorstanding, estimated 4.5/5) and the Revel Performa4 C245 (center, estimated 4/5). See every Revel Performa generation.
Pros: The larger Performa4 standmount, pairing a 6.5” ceramic composite woofer with a 1” ceramic dome tweeter in Revel’s seventh generation Acoustic Lens waveguide, crossed over at 1.7kHz. Its measured predecessor, the Revel M106, scored a 5.62 Spinorama preference score (7.87 with a subwoofer), and the bigger woofer reaches 43Hz (-6dB) for fuller bass than the Revel Performa4 M145. Dual binding posts allow bi-wiring.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Revel M106. Sensitivity is only 85.5dB, so it wants more amplifier power than most bookshelf speakers, and at 359mm tall and 11kg it needs sturdy stands.
