    I remember looking inside some old Altec-built cabinets from the 50s that had fiberglas sheets in them which were held in place by squares of cardboard secured by screws (I think).

    I think the cardboard idea would probably work pretty well. The fiberglass in my Magnificents was held in place with long staples - Altec must have used some special purpose staple gun on them....

    I got the blue jean material installed in one of the cabs. Fairly easy material to work with - ended up cutting it with a wood chisel and then scissors. There are some pretty tough bits in there - I won't even ask which part that is, but no zippers yet.

    Pic is of the back (upside down). The cardboard rounds hold things very well in place. A bit of open space for the diagonal brace, internal brace (back screws into it for more rigidity), and the crossover at the bottom. The left side and bottom of the cab also have the denim material - hopefully there is just the right amount in there.

    Just need to mount the 604 and connect up the crossover - things are getting close.
