#2 GR-Research NX-Treme: $9662 per pair for the kit with subs (assembly required) GR Research eBay
Pros: Amazing in terms of soundstage and imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box. One of the highest sensitivity speakers around. Open baffle mids, highs and bass (using GR-Research Open baffle subs). If you have not heard open baffle bass, you must hear it in person, there’s no going back. Amazing in terms of imaging as the speaker can radiate in all directions and not have internal reflections due to there not being a speaker box. Can easily be driven by tube amps due to the mild impedance. Measured bass extension of <20Hz (-3dB).
Cons: Very tall and will require GR-Research open baffle subwoofers one on each side
How it compares: Just above it: KEF Blade One Meta - $25338 more, 6.5Hz lower bass extension (-3dB). Just below it: KEF Blade Two Meta - $18338 more, 7.7Hz lower bass extension (-3dB).
