The enclosures are also very quiet. No dreaded single standing-wave coming out of the port, either.Very few audiophiles have ever heard a quiet-enclosure, clean-diffraction loudspeaker, including those responding below to your post who just don't know what they are dismissing. The effects on timbre, expression and attacks are considerable.
IME the effects are most audible on real stereo recordings of acoustic music. Typical popular genre recordings - multiple close mono miked mixdowns - have a lot of phase and timing errors and cancellations built in already, which could easily reduce the importance of diffraction. Tongue in cheek!
I have not heard a single sharp-edged speaker I can live with, since buying the spheres. Not even mini-monitors plus subs where edge-shape shouldn't matter, but IMO still does.
Even back then the 'spheres were 'bleeding-edge audiophile,' using good sounding Philips yellow-block film capacitors in ladders for each C in the circuit, air-core coils, and low L resistors. No low-pass just R and C to Eq the mid-bass* driver's Z-rise. * It rolls off after 3.3 Khz.
Foster, Japan drive units. Easy 8 ohm load, 91db/w/1m, 35-13k +/- 3db.I bought them instead of a pair of almost new black-mesh QUAD 57s (among some other lesser options). No down sides, almost as good at 3D, open throated on singers - which I've been for over 40 years, deeper bass, and went louder while still clear. They have revealed and assessed every other change I have made to the system since.
? e.g. Polystyrene capacitors versus teflons for passive RIAA Eq? A mixture is best, as for MF R's, but bulk foils are slightly nicer, and less selecting needed.
They have confirmed my preference for real stereo recordings of acoustic music (?simply-miked IE NOT multiple mono.) I listen to acoustic music and sometimes sing in it, at least once a week.
They can be aimed very precisely as their stands are dished, which doesn't hurt at all ;-)!
John Dunlavy 'respected' them, his own words to me when he was based here.
