604's are back they sound great.

[voice of the theater]

I am so tempted to, I don't think these sound as good as the old cabs and was darn tempted to swap them out just for shits and giggles.......hmmmmmmmmm maybe tonight yet. : ) I actually drew up a new design tonight. I'll post it now so I can get some opinions on what others think.

Please let us know how the restored drivers sound if you swap them out into your original cabinets--you may be pleasantly surprised and decide you don't need to build any more cabinets. I used to own a pair of cabinets (Heathkit AS 101's which were manufactured/stock with Altec Valencia drivers) almost identical to your original cabs (but not "DBR") and they were fantastic sounding. Here's what they looked like (click on images for full size)--do these look familiar to you (other than the grill cloth) ?
