The company I work for has 1/4" alumanium come in on these 12"osd 10"isd cardboard tubes. Don't care about port noise in a spl box. The only problem is 28" is the longest I can get. So it looks like 1 port instead of 2 //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I get mine free at work and with 1" side walls not resin needed! I think 1 10" port should be enough. Thanks for the heads up though
