What are your Super Tweeter findings?

I took the pictures because I was planning to start a thread on the TAKETs Andy . I just haven't been able to find the time recently .

Here's mine sitting on top of my Tannoy's with my external XO made by Mr. RFC. These super tweeters shouldn't really work and now that I have a good idea of how they work I can understand why some people are sceptical. They do seems to do "something" to the soundstage. I suppose it's very much user dependent upon if that "something" adds or take away from the musical enjoyment.

I've just noticed Barry's earlier comments and looking at the specs Taket do claim they come in at 20k. However, the manufacturers specs are very sparse and I think it extremely unlikely they just suddenly start making sound at 20K (that would be almost impossible). I would experiment with a bunch of budget film caps. A posh one can be used once you have found a good value.

Thats my understanding of how they work and probably explains why I "think" I can hear what I'm hearing. I've spoken to a few people who claim that these supertweeters kick in a lot earlier than 20K.

To be honest Andy my findings were the same as you stated in your original post. I have not spent too much time with them connected as I have not had my system up and running much over the last few weeks. I will et back to this post when I have evaluated them further.

Bear in mind the 40k ohm impedance. Any thoughts on usual cap values for tweeters are out of the window. I suspect these tweeters will be resistive rather than inductive. That may be why they 'come in' above 20kHz, becoming more resistive as frequency drops.

Yeah, fair comment.

Agreed - it is unfortunate that TAKET do not quote the -3dB points for the frequency response.

Again the impedance of these devices is somewhat ambigious. TAKET quote: "infinity - 4kOhm (DC -100kHz)". So it is anyone's guess as to what it is at ~20kHz.

However, being a piezoelectric device the impedance will be high and resistive.

It was actually the lack of technical info that put me off the Takets when I was looking at super-tweeters.
