Well i just order the AV15 Subs at $180.00. Now i just need to find some 20" or 24" sonotube. Can someone tell me where I can order some sonotube. I don't know what side walls it need to be.

Call your local building suplpy stores. They should carry it. It is called sonotube (brand name) or cement form tubes.

Thanks JRace.

Ok. found a local place to get sonotube....but they just have 18" and 24" at 12ft long. The 18"-12ft is $34 and the 24"-12ft is $55. Would the 18" be ok for a 15" sub with the port at the top or the 24". The sub i'm going with it the AV15. I'm thing of the 24" if the walls are thicker then the 18. If i go with the 18 it will be 50" tall or the 24 will be 41" tall.

I would like to tune it around 16-20hz with a 4" flared ports...don't know how long.

Thanks.

If you put the ports at the top then there's no problems with the 18" diameter sonotube.

To tune around 20 Hz you'll have two ports of 27 inches long, if you go for 16 Hz they will be around 44 inches long.

Thanks Simon5. Right on time. I went and got the 18" diameter yestherday and the wall on it is thick. I will be putting it together this weekend. Well i'll start it to night after work. I think i'll go for the 16hz.

What's the wall thickness of the sonotube?

soloxp · 25th March 2006, 05:47 AM

1/8 wall.

Keep in mind that some of the sonotube junkies will suggest some extreme alignments. They sound great with much as "normal" levels, but by the time you crank on the big knob, because you've had 14 beers and all your guests really really want to dance...

Well, it ain't pretty. Go a little higher on the tuning, unless you plan to underpower from the start.

Thanks Bogie

But this is only for HT.

Guys i need your help. This weekend i tryed to cut the plugs for this 18" sonotube. If i cut it 18" D it will not fit in the tube. It will fit on top of the tube. So i said ok i'll cut it about 17 5/8 it will go in but i'll have about 1/4in opening on 1 side. Here a pic
