Thank you Wayne. First, I will like to ask you about specifications for this Stage Four/18" and if this driver has the same behavior than the 15" model in my actual SET amp/3.5 meters throw but with more bass extension. I have some problems with the Eminece dealers because the Magnum model is out of stock and they only import 25 units minimum (Eminence require), so my options in this moments are JBL 2226, Omega 15 or 18 and KIlomax 15. Since you advice me that the better match will be the Omega or the JBL, I'm searching all the possible configurations. One more question: there is some important sonic difference between the tweeter horn in the box, actual bass reflex design and the horn on the top of the box (with the eminence driver/horn fixed with a bracket or with the eminence driver and the wood horn)? Thanks a lot in advance, Beto
