All our base are definitely belong to them!

Weird looking driver, that's for sure.

Interesting!

Looks like it doesn't have regular spider, so there's only one suspension structure like a dome tweeter. I'm wondering if there'd be any VC rocking/robbing issues since such construction can not assure pure axial motion, especially in large excursion....

Kind of look like the modern edge driven shallow automotive subwoofers.

They also attract squirrels. . .

They look like Dalek bumps.

Hello All,

No rocking or rubbing at full excursion. True pistonic action at all levels up to Xmax. Similar in design to the Fostex SLE Edgeless design. Fully tested and very nice drivers. Very tight, fast and solid low end.

spkrparts.
