[quote user="Paul S"]Piezos, anyone?Paul S[/quote]
I have a local friend of mine lent me PHY TW37 tweeter. It is French-made piezo driver:

I was running it last night and it was not as horrendous ...

Hi Ronnie, I'm glad you solved your trouble and it was just a matter of balance in the frequency response range.The singer's formant is an ability that opera singers learn, in order to stand louder than the orchestra and be heard at the rear rows of ...

Weren't these speakers (at least in Germany) normally used built-in (infinite baffle situation)? And I don't like the word "open baffle" because it can mean anything. It reaches from quasi-IB like proposed by PHY-HP up to that more and more crazy con...

How does the SPL/dynamic range correlate to frequency? Most of the old 10" drivers can play louder if not pushed down too far. I think as the years passed, the Tannoy had like most similar drivers a sort of "sliding scale" dynamics, and they would pl...

[quote user="Romy the Cat"]Ok, I got my two more PP2000, not I have 3 all together and I need to find how to use them. My little celebratory mood with PP2000 is much shorn live and my old PP2000 flying back today to Canada for fixing the problem with...

OK, I guess I am a little confused about how you get * enough * acceptable tweeter-less sound above 10k Hz that you can wait to cross over at 13k Hz. I don't know the Vitavox S2. Are you saying the S2 goes strong, clean and...

Yes, the similarity between the horn system and the Baba-Jaga hut on fowl's legs is uncanny. The system might be only loosely based on text book principles, but did you notice the use of cotton isolated wire connecting the speaker syst...

Chris,
I’m not familiar with PHY-HP cables from France. January the cotton-insulation on the cables is very nice idea but there is a lot more to it then juts the isolation material. Anyhow. If you do not mine then I would like to keep the subject of...

Mr. Witmer seems like a very thoughtful and well-spoken person who is taken with the aesthetics/approach of various Japanese sound Senseis, most of whom are in turn rooted in "historical" American and/or English audio sensibilities. I'm afraid ...

OK, Romy gave me an oppotunity to hear the system with the injection channel, so here's what I heard.The injection channel affects the presentation in a minor and in a very major way. Minor in context of already well accomplished Melquiades/Mac...

Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

Kids, do not let kids to subscribe the popular audio-freakish myths of the records spinning people about “the extraordinary beauty” of the Denon cartridges. Yes, the myth has some reasons: many more expensive cartridges are bad, very bad for th...

Yes, yes. This ooops thing is important.
For many years I happily listened to PHY KM30 fullrange in crazy
thin-plywood semi-open baffle boxes. And - apart from loud piano music
- they are really quite terrific. Very communicative and easy to get...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...
