Any KLF-20 owners out there?
The reason is that I'd like to know the length of the ports in your speakers. KLF-20s are supposed to have great deep bass response with twin 10" woofers each, but mine have never been that good. In fact, my CF-1s have better bass extension.
Now I bought mine used and just realized that the plastic port "mouths" (two in each speaker) look like they should have a pipe extension on them. As they are, the ports are only about 3" deep (and flared like a horn) which seems awfully short.
Any help would be appreciated.
