Hi all, I have a t350 horn that I recently got out of an old cabinet at a junk shop which does not work. If I connect it to my Marantz 1030 amp it will only play very faintly as if you are listening to cheap earphones laying on...

I am putting temporarily the project with tweeter amplifier on hold. The problem is that I can’t get what I need form my tweeter.

Hello Romy,Which other output tubes have you considered? I researched ‘suitable’ output tubes to drive tweets a while back for compression drivers [Be domes] — but not phenolic domes. Reading of your results with the EV tweet reminded me of how sweet...

I recently spoke with Paul Eizik regarding the criticality of the open-air mounting of that driver instead of baffle-mounting. I decided to go extreme and to get rid of that plate that I had under the driver no mater now small it was, also I thought ...

Rich,
if you have T350 (not T35) then it would be shame do not use them. Make sure that they are not ST350 and not 350A 350B or whatever later modification they were. If you did not use the truly wide dispersion driver before then it might take som...
|
|
A lot of people ask me about those drivers and I’ll try to compile my vision about them. I did try most of the possible tweeters: dome tweeters with cloth cones, varies type of hard metal domes, compression drivers with aluminum, titanium, phenolic a...

It is incredible how stupid sometimes our audio steps are. A few days ago I was complaining that sound of my T350 tweeter suddenly started to bother me but it was no the problem with the tweeter but rather the problem with my own moronity.
A f...

Very nice mounting. Hopefully the ridgidity will not cause any other unwanted vibrations from moving the assembly ever so slightly. I doubt it could be heard if so. Having used the T-350 (and t-35) over quite a long period from the mid 70's through t...

Very interesting application Romy, I really like the adjustment system that you built in. I have some EV tweeters in the shop, never even listened to them. Steve Schell and I haven't gotten to the point of trying tweeters in our field coil system yet...

I think I have too much time on my hands or use my time in highly stupid fashion but I decided to do today the experiment about witch I was thinking for a while. The experiment was “methodology clean” and lead me to quite interesting discoveries. Sin...

Well, it looks I’m near finding a more or less acceptable setting for the T350 tweeter. Ironically and completely accidentally it is not far form I use to be. It is still on the slope at 20Hz (since the T350 is pretty dead at 16kHz) but now it is &nb...

Bud, perhaps it does makes sense to try the “dotizm” one again. I quite severely review my view on the way in wish I use tweeter. I still am trying to make T350 to work, let see what I end up with. Nowadays my T350 sitting in 3rd order crossover, it ...

[quote user="Romy the Cat"]Now my midrange channel need no upper range diffusion and now I feel that the result I’m getting from T350 is too soft and too transiently slow for S2. So, I kind of very mildly begin to look out there and to try top fugue ...

Bud, the replacement diaphragms are available all time. On Ebay and everywhere else they are being sold by Bob Crites. He holds the original manufacturing rig and he can do them in unlimited quandaries. I own the original diaphragms but I do not use ...

The recent events in my playback made me to think about he new prospective duty of tweeters. Since the Super Melquiades was enlisted for duty the Vitavox S2 got it’s own dedicated amplifier channel and stopped to “see” the coil of upper bass driver. ...

[quote user="cv"]How are you crossing over the SA tweeter?[/quote]
Currently I cross them with second order at 12K, near Bessel Q, but not exactly. I did not play with crossover trying to tube it more precisely. It turn out the my driver was too “fr...

As I have mentioned previously I’m slowly in a process of assessing other opportunities for my Macondo, since the EV T350 driver it too soft to be paired with Vitavox S2. While I am doing it an old observation keep knocking in my head. A few years ag...
|
|
Listening my Macondo with new “Fundamental channel” I noted that my tweeter is not as effective as it use to be. The effect of “not-effectiveness” is very minor but at some recordings it is notable. My T350 still sorts the Vitavox S2’s top but it als...

Have you read the thread on Altec 19 becoming 21S?http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=13135#13135The Opera room thread is also relevant. To answer your immediate question, an EV T350 with a small enough cap can s...

What kind of futzing would it take to work an attenuated T350 or something like that back in there, just to check it against massed strings and the other impossible-to-achieve standards that tell everything about the "mid HF" qualities?All that x...

|
Jessie, do not forget also while you do your alignment experiments to listen the system from different distance. Get a reference whatever it is and then make a step back and a step forward. Try to discard the upperbass changes and pay attention only ...

[quote user="cv"]AlloI had a theory that the bug screen was helping to damp horn modes/refelctions caused by a mismatch between the S2 internal flare and the horn flare rate. I have 340Hz flare JMLC horns, which may be expected to give less of a mism...

It is very uncommon, practically never happens but still very rarely it is possible to talk about sound or playback systems from a prospective of “absolute tone”. Yes, the audio people love to take about tone of their audio but in 99.999% those audio...
