Can't find thread

I ran across a thread with pics of an unfinished system where the woofer cavity was in the cement floor.

I can't find a good keyword that gets me the thread.

Any idea what the subject was?

I used mine for a wine cellar... :banghead:

I found this after a Google search on the name of the big pictire, totalhorn.

And I spent 11 years in Italy and never heard of this. :(
