I fired up my new A7's for a test run today, and the cymbals are distinctly missing in an A/B comparison with my other set of speakers, which are nothing special.

Here's what I've got:

808-8A drivers
809-8A crossovers
511 B horns
515-8LF GPA

I assume that the problem is either with the crossovers or the 808s. Does loss - or absence in the first place - of the very top end typically indicate failure in one rather than the other? Do I have the right drivers in the first place? (3,500 sf cabinet shop, all open, no walls, rock and roll) I'd planned to do some crossovers as per Panomaniac in the future, is it time? I'd kind of like to get them up and running for a bit before I start buying more stuff.

I sure would appreciate some help.

Thanks,

Ed
