Pros: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement, with strong bass authority rather than a rolled-off, thin low end. Wide, constant horizontal directivity through the midrange and into the treble (about ±60°, wider than most horn-loaded designs which tend to run closer to ±40°) gives a wide, stable stereo image without needing to toe the speakers out and lose top-end energy. The reviewer listened for an hour-long sessions repeatedly without listener fatigue, across two very different rooms, with consistently great results in both. Extensive connectivity: USB, Optical, Bluetooth, analog, 3.5mm, AirPlay 2, and 24-bit/192kHz support; comes with a remote.

Cons: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC. The supplied ethernet link cable between the two speakers is short - workable at close range but not long enough for wider speaker placement, so budget for a longer aftermarket cable if your setup needs it. A dip around 900Hz shows up in the on-axis measurement that the reviewer couldn’t fully explain (ruled out the ports as the cause, suspects cabinet edge diffraction), though it wasn’t something that bothered him in listening. At $4,500/pair, this is a serious investment for a bookshelf-format speaker.

How it compares: Just above it: Buchardt A10 - $200 cheaper. Just below it: Presonus Eris Studio 8 - $4038 cheaper.
