Creative Sound Solutions is the only place I know of that
has Jordan Speakers and some Tangband models not carried by
PE.

On the homefront (CSS is in Canada, I am in Wisconsin USA)
a test switch of drivers in the PVC boomtoobz has, I think
made a substantial change for the better. I swapped in one
of my FE127e's and am now comparing the sound of the RS 1197
(which has none of the modifications that have been mentioned
as tweaks) and this Fostex 127.

*pic*s available of the boomtoobz when digital cameras
get to be about eighty bucks or so.
