Welcome aboard... What's with the tweeter mounted on the Summits???

Good Lookin Hello from us

Welcome to the club Hans! I've spent time in your wonderful country!

Thanks guys,
Hello Tom,
The tweeter hanging on the top of the Summits makes the soundstage wider and you can hear the cimballs ,hi-heads etc clearer without any sharpness.Of course I use a filter for the tweeter ,it comes in between the 7000/10000 Hz. It is a very nice ribbon tweeter from Hi-Vi . Like you probably know that if you (ears) become older the high tones become less, I think that counts to .
Hello Mark,
We do have a beautiful country but I think that in the USA are also beautiful region's . I have never been there but I want to go in the future.

I'm curious to hear more about your "supertweeter" installation. How is it powered/wired? Is the "filter" (? crossover) a DIY design, or commercially available?

The filter is originally designed by audio-smile in the UK but mine local (tweeter)suplier have change the paralel coil in it . I shall make some pics of it

Wow, that is a serious rig! Good looking Summit and an interesting tweeter.

What is the finish on your Summits? They look gorgeous. Even since I got my Theos in Zebrawood I now have this new found appreciation and infatuation for good wood finishes and yours is no exception.

Thanks , Joakim, the tweeters sounded indeed very nice (sweet to) and I enjoy the Summits even more ..

Thanks Jordan, We call that veneer : ' Palissander ' ,I think you call it : 'Rosewood ' . It seems that it is a jubilee version. I do like it to including the alu finish.

The subwoofer enclosure looks way too big (tall) on the speaker in the third photo (the one with the bird), to me. What modifications did you do to it, or is stock and I'm just imagining that?

Just stock ,a ML stylos

Thanks. It just looked so tall and thin to me.

Do you have any timing or phase problems? I would think you might have some problems with coherence/integration between the panel (line source dipole) and ribbon tweeter, not to mention challenges with volume, unless managed manually. Looks cool though....

I can't measure that sort of thinks but mine ears told me that is oke , a ribbon tweeter comes close to our electrostatic , the sensibility of the ribbons are almost the same as the Summits so the volume integration is no problem. Earlier I had the Hi-Vi rt1-ii (smaller)and that sounded not so good they were sharp on the ears .

update new mods; replace the supertweeter filter components by Munzdorf components , sounds much better.
Change the 3 way cross-over from the Logos centre in a 2 way with 12 Db filtering . The woofer runs till 250 Hz and the panel comes in ad 150 Hz.In the top no filtering . Added a super tweeter like the Summits .Change the Logos membrame (normally 2 pieces) in one in 1 large piece .
