PVC tubing for enclosures

[kgveteran]

To cut cost and look for a more interesting enclosure I priced some 8" PVC tubing (the thick green stuff ) for enclosure purposes.Has anyone used this material before ? My thoughts are to use the 8" stuff for the woofers (6.5" drivers),6" for the midrange(5"mid) and the 4" for the tweeter (just for looks).

The enclosure for the 6.5" drivers will be sealed and small because they will be handling only 80hz and above.I'm sure they will be at least .5 cu. ft. ( or slightly larger if needed )each.The midrange will need an even smaller enclosure.

The xover will be external in the base.Whatcha think?

There's a discussion here somewhere on this already. A 6" driver in an 8" tube might be pushing it. Standing wave issues increase. Total speaker depth has to increase due to loss of volume in the "corners" compared to a box. Baffle, you do NOT want it to be round with the driver centered - that's the worset thing you can do.

In other words, for anything other than a subwoofer, take care and plan very very carefully. There are places where a tube may be the way to go, (mostly if it's a quarter-wave pipe setup) but understanding why and when is just as important.

Yeah I was pretty set on pursuing that path but it got shot down pretty quickly, lol.

There was no shooting down, my friend!

Flying by flapping your arms simply doesn't work. :P
