Electro Voice T350 Compr. Drive - Currently available replacement with similar Sound?

[tiefbassuebertr]

This deluxe VHF compression driver T-350 was for me one of the best sounded horn tweeter system at those days. Much more better than the T35, although the same voice coil and phenol cone (diaphragm) is in use.
In this case follow questions:

1) What could be therefore the main reason?
2) Which currently available horn tweeter systems (except BMSpro) are presently on the marked (I don't find a successor by Electro Voice itself) ?
3) Are there significant sonic differences between the individual years of production?

Here some images and URL's from various time aeras:

GoodSoundClub - Romy the Cat's Audio Site - Electro-Voice T350, T35, + Fostex tweeters. (delay adjust assembly)
One offer I have found about the ebay USA, item No 200636124805

ST350A followed using same diaphragm, different horn and then the ST350B with ferrite magnet... Not currently available there should be plenty of ST350B's lying arround. They were in loads of EV cabinets. I've got quite a few and keep finding more - which is unusual round these parts...

1) The T-350 has a much better horn design than the T-35, it sounds smoother, plays louder (so requires less power) can go lower and has better dispersion characteristics.

2) The Eminence APT driver is available with several different horns, the APT -200 most similar to the T-350, and has more extended response and far more power handling with similar sensitivity.


3) Different magnet structures were used over the years, ceramic magnets replacing the Alnico. The sonic differences were not much, though the ceramic units were not as pretty, and weighed more.

Shimming and alignment of the diaphragms in T-35s and T-350s is critical, depending on the care taken, large deviations in sound are possible. If the diaphragm is not perfectly installed, distortion and ragged frequency response result.
The voice coil takes very little power to burn, most T-35s or T-350s used for PA use have been re-diaphragmed, and often proper care was not put into the process. If you are not familiar with diaphragm alignment, I’d suggest steering clear of units that you can’t listen to or measure before purchase.

The photo on the left below is the APT-200, right is an EV ST-350.

New Fostex 500MkII probably will sound equally pleasant and is little more detailed . It is expensive though. In my friend's system I preffered it to TAd ET- 703 which in my system I liked more than T-350. Jensen RP-302 is splendid too although as old as T-350. I didn't like T-35 at all.

Hm not sure if it's related. I did not own or buy RAAL speakers.

It is as much related (actually more) as the fact of you having a pair to sell ;0) just put them on Swap or ebay
