Danny or anyone else,
If this has been already discussed and I missed it, I apologize.
I have read much about how good the 8" subs can be. I have read about how good the OB-5/7s are.
What about an OB-5/7 open baffle top end mated with a 3 x 8" open baffle bottom end for a true open baffle full range speaker?
Easy to do? Require crossover changes on OB5/7?
Any thoughts?
