what are the thoughts of stand alone super tweeter

Pro: more air and space, greater definition throughout the frequency range, and cleaner transient snap.

Cons: makes your speaker a tougher load (some companies deny it but I think there is no physical way around it), potentially goofy look.

Hifi+ has reviewed a couple of them - the Townshend and the Tannoy. They couldn't explain it technically but their impact was obvious. They loved both and deemed them a highly worthwhile purchase no matter what speakers you use.

It if funny how some can embrace changes a copper wire can make but then refute the concept of a supertweeter.

I also find it funny that Kal is looking for "independent corroboration" when it is right here in this thread and in audio magazines. This is as much corroboration as we'll ever get.

Ditto for the impact different cables can make. There is no scientific proof! We just make our own independent analysis using the finest test equipment in the world - our ears.

My personal theory of explanation is in line with Markphd's. It must have something to do with interaction of the sound waves - and not necessarily the sound waves (or frequency level) coming out of the tweeters.

I am anxious to try a pair of supertweeters one day and see for myself what difference they make.
