I went to Lowes today because I needed another box of screws and wood glue for my current sub build. While there, I noticed some expandable/flexible aluminum tubing. I believe it was to be used as duct work. Would this work well for port material? Seemed to be about half the price of PVC and a 1/4 the weight. It seemed fairly sturdy- at least enough to handle air pressure from the 250watts going to each of my subs. Thoughts?
