I'm trying to replace an ancient pair of energy pro 22 speakers, but have yet to surpass them.
I really enjoyed the amish, but I like the energy's better overall.
I've got a diy aleph 5 amp and it has plenty of power for the less efficient 8530's.
I'd just like to try the zaph zd5's, but need to move 8545 and 9700's first.
My post is to query whether your intended upgrade to new driver, 8530 will actually improve the sound you looking for(my educated guess see below *). My expertise of scanspeak is limited, I suggest you ask people like Troel, he would be able to advise you on that before you proceed. Maybe he may advise you on upgrade on 8545 by changing x-over.
* I believe drivers with similar made of cone, eg paper, or kelvar, etc will sound similar ie have certain character esp. they are from the same manuf., Scanspeak drivers are no different.
