Default those look like bes planars from the 70s and


bertoni electronic speakers or something like that.

styrofoam panels driven by conventional motors.

the pair i had also had a tweeter that drove the edges of the panel.

they were dipole floorstanders.

i remember really liking them but cant remember what i replaced them with.

would love to hear them again with the rig i have now.
if it aint broke.........tweak it !!

I once tested one sound advance, to my ears the only use is standing free as a dipole, even OB sounded ugly, not to mention the specified use. Very good impulse responses, but not so good THD, probably best suitable for electronic music.

Default well.....

I did not take the time to load all the PDF files but form what I saw it looks very familiar. If this unit uses a plastic film diaphragm then it is almost a direct copy of what I co-designed in the late eighties. We manufactured under the name of Highwood Audio and distributed our speakers under the Sumo banner (out of California). The photo that I saw looked as if it could have been one of our prototypes. Nice to know that someone liked it enough to copy it. Regards Moray James.
