I was thinking of making some experimental boxes to try out diffrent
speaker unit combinations. Sonotube seems a useful idea with a
top/bottom or front/back in my case. Anyone used it and can report on
its acoustical properties? Andy

I have several friends who have used Sonotube in various configurations. One
made a tower by slitting a sonotube and bonding a wooden mounting plate to
the side of the tube. Others have added tops and bottoms and used them as
subwoofer enclosures with the woofer mounted on one end.
