iono what they call it but its made of thick paper card board. if i can somehow moisten the ends of it, i might be able to flare it. seems like it would be less work then flaring an abs pvc from home depot or lowes and then add a few layers of resin when the flare is done. doesnt sound bad for $8 :) prolly use it non-flared for daily though.

There's a tutorial online somewhere that shows how to make wood flares for them. Saw it on a HT site somewhere and it shows how to do an internal flare also. Do a search and I'm sure it'll come up. If not shoot me a PM as I know I have the link saved at home...

Here's an external flare I did for a 10" one. Pic doesn't really show it, but I used a 1/2" round over on the inside and outside. Came out pretty nice and no port noise even without the inside part being flared.

im deciding to use a 10inch tube for my 9515. that way, i doubt there would be port noise. im thinking that if i soak part of the end of the tube, i might be able to flare it using some kind of bowl and let it dry like that.

yeah you can flare using a roundover bit and router, i do it on mmost of my boxes. With pvc all you need is to add a "flare baffle" or essentially another peice of wood on top of the pvc to flare it. Hope you know what the hell im talking about :)
here i found this link of a box i did a while ago

Just put mdf on each end and put the sub in one and an aeroport in the other.

The guy with that crx has pvc tubes now but the cardboard form tubes worked pretty good.

I think he cut a piece that fit around the outside of the tube and glued the wood to it.

I'm actually surprised at how many folks *aren't* using Sonotubes et al for their car audio projects. They are widely used for Home Theatre sub projects - large ones for the enclosure (18", 20" 24") and the smaller units for the ports (6", 8" 10").

Chad:
As per what the other poster stated, you create a "plug" for the ends - two pieces of MDF; one larger than the diameter of the tube and the second that fits inside the tube. Glue the two together and there you have it. Instant enclosure in a couple of hours. :)

Here's an on-line Sonotube Calculator I use periodically to determine tube sizes for enclosures:
http://www.quux.net/roo/diy/sonosub/sonocalc.html

Sonotube ports:
Sonotubes are great for ports - they are cheap and come in a variety of sizes. As a couple of folks have mentioned, some brands have the "extended" sizes - one tube fits inside the other. These provide excellent choices of sizes since a '6' tube measures 6", '6+' tube measures ~6.5", '8' tube measures 8", '8+' measures ~8.5", etc.

Collo has extensive information on his site regarding port flaring. Very interesting read. He has also created Sonosub design software which is very good:
http://www.subwoofer-builder.com/flare-testing.htm

Regarding trying to flair a Sonotube, I think you would have problems since you are only dealing with cardboard, and we all know what happens to cardboard when it gets wet.

Best,
Mark

you could try using paper mache on a mould and attach it to the cardboard and then resin\glass it to make it nice and strong?
