Title: RM30 and super tweeters
Post by: Hipper on 19 May 2019, 10:13 am

This article describes the use of Aperion ribbon super tweeters to enhance the sound of Polk LSiM 707 speakers:

I've never used super tweeters but have read claims that they enhance the sound although there's no obvious satisfying explanation. Bearing in mind my RM30's tweeter is said to go to 30kHz, would there be any point in trying them?

Has anyone any experience of using super tweeters with VMPS ribbon tweeter products?

Brian offered a spiral ribbon super tweeter, at one point. 
So, it was something that must have been worthwhile to explore. 
I can't imagine that a super tweeter would hurt a system.  Just play
with positioning, even aiming the tweeter around the room, to get a
better blend, in order to add air and spaciousness.

Here's a review of the tweeter:

I always wondered about AMT tweeters, as super tweeters? 
AMT tweeters seem to be all the rage now.  They might be worth
checking out?  There's even stand alone versions, that look to be
designed for system add on.  Search on Ali Express.
