Anyone try using PVC pipes to make a dash speaker pod? I want to try this but i'm not sure if the PVC material would make a poor enclosure.

I figure i can just cover it up with grill cloth.

I'm only using 3" woofers btw

Line the walls with some kind of deadening material and stuff them with fiberglass or polyfill...

Parts express has poly fill in 1 pound packages.... fiberglass insulation (think pink stuff) you can find in hardware stores.

you can buy polyester fiberfill in any arts/crafts/fabric store or in the crafts isle at Wally World. aka Polyester pillow stuffing. Usually about $4-$5 for a 1lb bag.

I had considered this also but 2 things bother me. First is the room for the air flow from the back of the cone. Second is that a circular enclosure seems to be a perfect setup for standing waves since all sides are equidistant. I read somewhere round enclosures were absolutely the worst shape. And many speaker manufacturers take great pains to not have any parallel surfaces in their enclosures.

Just some thoughts, someone smarter than me can comment if I am out to lunch on this.

From what i've seen in the DIY home audio world, speaker builders round-off t he back of their enclosures, kinda like how a pvc end cap is shaped. Not sure of why this is better but thats what they do...

Not sure what you mean here. Are you saying the enclosure doesnt open up/widen and that it would be like a tube?
