Where to buy 4x8 rigid fiberglass?

As the title states.
I'm interested in creating a resonator panel in the corner of my room, however - I've only seen 2x4 rigid fiberglass. I know OC offers 4x8 on special order, but is that rather expensive? Besides, 703 doesn't have a great coefficient at low Hz, compared to roxul 80.

Thanks.

Most people just build a framework that turns 4 2x4 panels into 1 4x8 panel, or bond the 2x4 panels together with beads of glue or strips of tape or whatever.

What is wrong with that?

I guess you could also do something like get a piece of plastic latticework like this:

And use plastic ty-wraps to fasten the smaller batts into a larger unit.

RPG will do a 4'x8' either as a straight absorber or BAD panel (combination absorber / diffuser). If you need help there I'm an RPG dealer, please contact me PM or via the my website link below.
