Hi Wayne,

I am curious about your push - pull version of the Three Pi subwoofer. Is there a set of plans available for this version of the Three Pi sub?

I would appreciate it if you would send me a copy if the plans are availble?

Thanks for sharing!

Norris

I never made such a thing. But if you take two three π subs and face them together, one with the woofer installed backwards, magnet out, you will have a push-pull sub. Place them close to one another, just to the point where the cone of the forward-facing speaker will not strike the magnet of the other at full excursion. Make your cabinet to position everything that way.
