Hi Wayne,thanks for the tip.I said that cost was no object,but I over stated myself.The woofer you recommended costs about 159 bucks.I'm kind of steering towards Peerless or Vifa,as they seem to be more affordable.If I stay with my orginal idea,I will use the Seas 6.5 co-ax ,which I already bought and put a Scan Speak variovent in the hole left for the tweeter.The Seas speaker follows the same idea that KEF and Tannoy are using with the tweeter mounted where the dust cap would be.I got lots of ideas swirling around in my head,the speaker building hobby has already sent me to Audio Asylum.....Mark.
