Which commercial super-tweeter should I consider for maximum treble
with maximum SPL? |

The old EV T350 is considered by many to be the best tweeter ever made. I have
a pair and I love them. They have big magnets and they are super efficient.They can be too hot for some systems and will require an L-Pad or resistor to cut them back. Problem is that their reputation has caused them to sell for up to $900 a pair on E-Bay. The newer versions, ST350, sell for less because they aren't "vintage" and they probably aren't quite as good. The EV T35's are OK but have less output than the T350's. The old Altec 3000's and University HF206's are nice and pretty efficient too, but they won't give as much SPL as the T350's. For new tweeters, maybe TAD or Fostex? |

We are however talking about a horn driver, and it is unlikely to have usable response for more than 4 octaves, and to get maximum efficiency in the audible treble some of that response could be "sold off" by moving the resonance of the front chamber into the audible range. If so - and please understand that no claim of technical accuracy is made, this is explained in an illustrative way - then it is likely that its _useful response_ would end no higher than 24 kHz. No absolute statement of any kind is made in this post, the actual specs of whatever treble driver this was about are unknown to me. -- ******************************************* * My site is at: http://www.muyiovatki.dk * ******************************************* |

Why did you have to dial faxback to get the specs then? - I would have thought they came with the unit - strange shop if you had to get them separately. Is there any super-tweeter which goes beyond 40 KHz and SPL beyond 96 dB? Probably not if you ask for both properties at the same time. As Ole Lund Christensen once said: bandwidth times efficiency tends to be a constant. Ya can't win in unlimited tractorpulling with something that weighs 500 kg.

With enough power it should be possible [at least in theory]. Right? No, in the context of the stats you asked about it is only possible to read the "96 dB" quoted above as a sensitivity spec incorrectly written. Sensitivity doesn't change with available power. For something that does exist, and comes up once every 12 years and then fails, you could try to search on the web for info on the ionophone design. It is woefully inefficient, it fills the room with ozone, but its upwards frequency response is very extended. You will also have the great feeling afterwards of having found information by yourself instead of just asking any stray question you can come up with.
