Question about OB H frame sub

[PDRCanada]

I have been wondering...hope you guys can help.

Open Baffle 12" subs set in a H frame.....Instead,could you use a 16" piece of heavy duty PVC pipe with the woofer placed in the center fastened to a wood (or whatever) type of ring? This would leave about 2" around the woofer to the pipe.
Would this work? Could you stack 2 of them on top of each other?
Problems with this would be....?

Thanks

Should be fine, if you look at MHK's gallery, the 7th guy down uses some sonotube, I think this is your idea also?

Thanks, that exactly what I was thinking.

Yes, it would work. I'm pretty sure that the dipole peak will be somewhat stronger/bigger with this type of frame, compared to a more traditional rectangular frame.

What length of pipe would you be using ?
