While we are on the subject of woofer upgrades to Pi speaker designs.
I was wondering if there are any current production driver upgrades to the Eminence Alpha 10" in the Seven Pi midhorn, that would be a good mate to the JBL 2226H mid-bass driver?
I see where you mention the JBL 2012H as being an upgrade path. But, since JBL discontinued this 10", they are hard to come by, and expensive when found.
I was wondering if the Eminence Deltalite 2510 would be a good inexpensive alternative? :
Maybe one of these Eighteen sound drivers would have the efficiency to keep up with something as crazy as a pair of JBL 2226J per bass cabinet in the Seven Pi speaker?
