Im curious about this,I've hung my hat on the MiniWatt N3,so for me the OB-7 and N3 are out for me,they just wont be efficient enought so I've chosen another path.Eric from Tekton Design has a very interresting speaaker coming out very soon OB-6.5 hybrid floorstander,I've already heard his OB-4.5 hybrid standmount and it was the best fostex based setup I've heard as a matter of fact it was very very good and 1 of the best speakers I've heard,but it just didnt have the bass or the output i needed.He has a cheap tweeter that he uses for people who want a tweeter,and i would be 1 of those people,but i would need a higher resolution tweeter than that,and plus i own a pair of X-Statik's and im quite fond of the Peerless India tweeter,plus i have experiance with the standard neo tweeter,and some of Hi-Vi planer magnetic tweeters.What i wanna know is are these 2 tweeters good at crossing high,i know their monsters at crossing low,which is how Danny likes to cross,and are the neo pdr with the cups are available as a stand alone part or just in the kits,any info would be helpful thanks.
