Large Size Bookshelf Speakers
Ranked #5 of 131 in Large Size Bookshelf Speakers - March Audio Sointuva AWG: $4150 Marchaudio eBay
Pros: Purifi drivers deliver exceptionally low midrange distortion - the reviewer calls them “world class” - paired with bass extension unusually deep for a bookshelf (F3 40Hz, F10 30Hz), reaching down to about 30Hz in-room with some boundary reinforcement. Sensitivity tolerance band measured extremely tight at 1.6-1.73dB, indicating excellent build consistency. Estimated in-room response is exceptionally smooth and neutral - one of the flattest the reviewer has measured, with none of the usual coloration descriptors (bright, boomy, nasal, shouty) needed to describe it. Distortion stays so low even at loud volumes that there’s no audible warning cue before you’re playing dangerously loud - a backhanded compliment to how clean it sounds. At $4,150/pair, ranked among the reviewer’s top three bookshelf speakers in that price range.
Cons: Correct listening axis sits about 7° above the tweeter line, which means shorter stands (around 24”) than typical bookshelf stands are sold at - get the height wrong and the sound scoops out in the mid/high frequencies. Moderate-low sensitivity (~82dB) is roughly 3dB below a typical bookshelf speaker, meaning close to double the amplifier power is needed for the same output; low impedance also calls for a 4-ohm capable amp. Horizontal radiation holds a wide ±60° only up to about 3kHz before narrowing - tighter top-end dispersion than the reviewer’s preferred ±60-70° through the treble, and the reason he left the previous generation off his all-time top-five list. Multitone distortion rises above the reviewer’s personal 3% threshold in the 1-2kHz region, though it wasn’t audible in his listening. Not intended to be crossed over with a subwoofer at 80Hz - designed to play full-range down to 40-50Hz, so pairing it with a sub and cutting it off early wastes its bass capability. Best positioned about 3 feet from the rear wall, requiring more floor space than many bookshelf speakers.

Large Size Bookshelf Speakers
Ranked #6 of 131 in Large Size Bookshelf Speakers - March Audio Sointuva: $3,995/pair Discontinued eBay
Pros: The Purifi woofer and Satori waveguided tweeter combine class-leading distortion with unusually deep extension for a compact cabinet. Erin measured roughly 83dB sensitivity yet found the speaker could still sustain about 96dB/1m with 3% THD not crossed until ~60Hz; compression remains exceptionally low until the deepest bass at the highest sweep. Horizontal directivity is broad and smooth, the early-reflections trend is readily equalizable, and the passive radiators avoid port turbulence while reaching approximately 50Hz anechoic and lower in-room.
Cons: Erin measured a 3.8-ohm minimum and an average load near four ohms; combined with ~83dB sensitivity, this demands a powerful four-ohm-stable amplifier even though the drivers tolerate that power cleanly. Vertical directivity shows the unavoidable woofer/tweeter crossover cancellation, so stand height matters. The original waveguide narrows somewhat in the upper treble compared with the later AWG revision, and the premium price is difficult to justify if low-level listening or an 80Hz sub crossover leaves the Purifi woofer’s excursion capability unused. Discontinued.
