You may not need 1 in thick, use 0.5 in thick but use copious bracing. keeps price of foam down. That pink stuff is nice, I have been eyeing it for a massive BIB with 12 in driver. You can also put the driver on the diagonal divider and turn it into a tapped horn sub - would have to redesign with HornResp but would be interesting to make a 10 Hz sub. I have also wondered how to make a collapsible 'take down' BIB with these foam panels and glued-on flexible rubber coated hinges (rain coat slicker material) and locking braces. You can flatten it and bring to a party to set up in a snap. Throw a pillow inside for stuffing. Connect a little 300 w/ch class D amp like the TAS5630B from TI (or one of the numerous multi-hundred watt DIY class D amps being built on the the class D forum) and rock out. It would look pretty interesting being all pink.

Bicycle innertube. Bond it at the bends and bungee cord it shut for travel. Do both inside and outside to fold flat.

Have press-fit top and bottom with a roll of gaffers tape?

When I pick up the sheets I will have to get in touch....I don't have Hornsresp (Mac user). Somewhere I modeled a 12" TQWP off of Martins sheets (10+ years ago). If I can find my files I might not need it. If I remember correctly, a 40Hz FS with a high Q can be tuned to around 15Hz and be wicked-low.

Not sure if this is foam core but sure looks like it. Posted in the Pass Labs photos section. Very cool.

It looks like a smaller version of a project Pass wrote about in Audio Express some years ago. It could be made of styrene sheets. Perhaps someone will enlighten us about its construction and provide a source for a set of plans. It could be a fun project in foam.
