First off I must agree with Bill and Wayne as far as using the 811B horn will be less than ideal unless you toe them in to the listeners position and that limits how many people will be able to hear the system like it should.

I still have that situation and then some since I use round horns which beam like a laser, but will image like not other horns if you can stand a micro-sized sweet spot.

I would also like to point out that the 807 driver if stock has a "symbiotek" diaphram and HF response will be limited. Installing a aluminum diaphram will help, but driver to use if you want Altec (or Great Plains) is the 902 with "Tangerine phase plug" and aluminum diaphram.

Regards to all!

Ron
