Since most planars (electrostatic & electromagnetic varieties) are open designs i.e. dipolar, I would think no matter how large they are made, they still won't generate much low bass because the front and back waves will cancel each other out. I was poking around Jamo's site yesterday and when I found this, wanted to get others' opinions: Jamo R 909 This speaker uses two conventional 15" low frequency drivers for the bass. But I'm not sure why they would produce more bass than an electrostatic design. It sure has a beautiful shape though. Anyone have ideas on this issue? Also, this model doesn't have a rear-facing tweeter so (I guess) it's really only a "three-quarters" dipole design....or maybe its engineers felt it wasn't needed? BTW: Infinity had similar types of dipolar speakers, including this model (that excellent site's homepage) which was one of the first near-hi-end speakers I had listened to, and which reproduced music in a nearly "being there" manner.
