a circular pipe isn't the most efficient way to occupy space.. a regular cuboid will technically occupy the same space in your vehicle as a circular pipe, and have much more internal volume..
I find a piece a 8" PVC d odda day so a go chuk 2 sound barrier 8's inna dat wit some dacron...how da go sound in a open air environment? put dem at either ends or seal one end an put d 8's isobaric?
Ruffneck, it depends, if the tuning of the pipe volume is sufficient for one sub, say it can will reach a resonace at 40Hz with one sub, then run them isobaric. If the pipe is very large, then put them on either end.
I can recall seeing an article in a magazine many years ago about someone building a sub with flexible pipe and a smallish speaker (I think 4 inch).
Does anybody have formulas I can use?
