Drool !!
Haven't heard Accuton but they certainly have a stellar reputation. Peter at PSSound has some Arcos tweeters in his personal car that were based on some home Accuton drivers and even over the Youtube they sounded amazing. I don't know how that's possible but they do, check out his feed and find his video with the Arcos demo. I'm too lazy to track it down for you.
here is the his unboxing video of the new Accutons. 2k Euro for the tweeters, 2k euro for the mids and 2.5k Euro for the woofs. I will only be enjoying these from afar I guess !
