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 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif 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 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
