"Corinthian"

Those people who knew of the "Conehead" saga  know how this speaker came about

Anyway... "Corinthian" is a derivation of the Tapered Pipe, but has 12 faces forming a truncated dodecahedral pyramid. It is the nearest construction I could make to a truncated cone.

The drivers used are the Seas clear cone T17RE and the Tangband clear dome tweeter. Series x-o

When building this I actually tightly fitted the vacuum hose in the top and sucked the air out to pull the sides together. (before I cut the driver hole and port of course ;-)   Was great fun finding where the air was leaking in and filling the pinholes with glue.
