Tuning a back loaded horn

The real wool is treated you will not have a moth problem. You tune a BLH from the driver down you shouldnt need to damp mouth but this all depends on cabinet design and driver choice. I could help you more if I knew this.

Third attempt to respond to Johnk question.

John, the speakers I use is at http://homepage.mac.com/tlinespeakers/FH/download/Sachiko-map-1v0-230307.pdf. I use Fostex 206E drivers.

Thanks

Rodmann - I put about 5/8 of a pound of polyfill packed quite tightly behind each driver.

The bass that was bugging me is greatly reduced, and somewhat to my surprise, the speakers seem to have more snap, more detail and improved midrange!

Man, back loaded horns are the bomb!

Thanks
Paul

Glad to be of service. Happy listening!
