Try that and pste it into the box. It loads for me from bookmarks.

I am frustrated. I just made a long message about backhorns and
blew it off, so here goes again.

Bill Fitzmaurice can help on these questions. Over years
he has built a series of designs he calls the 'snails'.
Snail one though... Snail 8 i think. These are speakers which
are designed to be high efficiency PA speaks for musicians.

There is a snail build in the current (August 2004)
audioXpress and on the cover as well. The snails have
a woofer facing rearwards into a divided horn which comes out
the right and left side of the enclosure. Imagine the letter
'M" from McDonalds and you'll get the idea.

Terry Cain also has a concept like this. It looks like
a standard BK16 from the Fostex manufacturer's design page
_plus_ a mirror image backhorn coming out the top. They
no doubt weigh a ton.

Another over/under design is from Nelson Pass called the
J-lo (also in audioXpress... I'll find the issue for you if
you like) which uses a single Jordan 92s.

I'm sending now so i son't lose this one. :-)
