Their 6.5" full range looks pretty good. It's just too bad it is twice the cost of the Fostex FE167E. I just emailed them to inquire the country of manufacture. If made in the USA or Canada, I would consider buying a pair and trying them in my Pipes (no pun intended).
Hmmm... banana fiber cones for the Fostex, right? Maybe those could be called, Mellow Yellow? Yeah, yeah - bad Donovan reference I know.
