Anybody have opinions on supertweeters?????

Search the archives here and at Audio Asylum. You will find much to read.

I'm also considering supertweeters for my Odysseys. The Murata does not have variable sensitivity, which would seem to be a critical factor in matching it to your speakers.

The Townshend is a ribbon, meaning it will have next to no vertical dispersion--it will probably have to be aimed exactly at the listening spot, including height alignment with your ears.

The Tannoys seem to be the most flexible.

If you get the supertweeters, please post back on your experiences.

I hear that they aren't much good on cabinets made of Kryptonite....

Sorry - just couldn't resist.

One thing I was wondering was is if it makes sense to reproduce sounds over 20 kHz if you're listening to Red Book. Even if the sounds in the inaudible range can modulate the audible sounds (audibly) in real life, it is my understanding thatred book can not reproduce sounds over 22.05 kHz, in which case the supertweeters would be reproducing either, at best, nothing, or at worst, noise that the CD player didn't filter out. Of course hi rez formats probably wouldn't have this limitation, and perhaps vinyl wouldn't either (can vinyl reproduce sounds in ultrasonic range?) Note that I am not stating this as fact, but a thought that I'm hoping someone with more experoience can comment on.
