This is an example of what leads to my confusion. Here is a data sheet on the 1225A HF cabinet. On the first page it says the 805B horn "operates from 800Hz to beyond audibility". http://altecpro.com/pdfs/vintage/Spe...%20Systems.pdf

Then down below it says the 1225A enclosure, with only the 805B horn in it, has a frequency range from 300Hz to 8000Hz. That makes no sense to me.

I'm now in the camp of just try it and see what happens. I know my 806A CDs go down to 500Hz. I'm going to tune my crossover that low and see what I hear. If I like it, who cares, right? If not, I'll adjust it until I do. The good thing is I know what sounds good...to me at least. I have a sound in my head that I'm trying to achieve. I really don't care what the numbers are.
I couldn't agree more, I have seen so many conflicting pieces of literature That I too decided to just go with my own instincts, Altec doesn't appear to be any more educated than the people on this board. And since were on the subject I'll never deal with GPA again either.
