I was afraid of this, a few months ago I purchased some GPA X-overs but for 604 8-g's. I haven't installed them yet. I have always heard that Altecs can have a shout or a bite to them up top, but with my 604's and X-overs, I have yet to have this type of problem. I can't wait too hear the new x-overs for comparison. GPA does some amazing things!!! Bill is the best!!!!
