Let's talk Tweeters!


Another thread which talked about specific speaker brands was taken over, so I’d like to start a new one.

Mind you, I do not believe in a "best" type of tweeter, nor do I believe in a best brand of speaker, so lets keep that type of conversation out, and use this instead to focus on learning about choices speaker designers make and what that may mean to the end user.

There is no such thing as a speaker driver without trade offs. Some choices must be forsworn in exchange for another.

In the end, the materials used, magnet and motor structure, and crossover choices as well as the listening room come together to make a great speaker, of which there are many. In addition, we all listen for different things. Imaging, sweetness, warmth, detail, dance-ability and even efficiency so there is no single way to measure a driver and rate it against all others.

Also, please keep ads for your 4th dimensional sound or whatever off this thread. Thanks.

I don't mind talking driver brands... we're unlikely to get a ScanSpeak or Faital troll to show up and start harping on the quantum effects of their drivers.  :)  Plus it helps to talk about specifics in case we want to point to specifications. :)

So maybe we should say "No proprietary drivers" discussed? :) Then we can talk about a specific midrange, and talk about who might be using it. But yeah, really don't want a paragraph or 20 talking about how speaker brand X is so amazing it isn't even a speaker anymore.

I was thinking of something, for those who think I’m a super AMT fan, I’m not, but I have the most experience using them in designs. :)

The following is true for me:

Some of the worst sounding, and best sounding speakers I’ve ever heard used AMT tweeters. I ascribe this to the vastly different quality of the tweeters, and the effort needed in the crossover by the inferior tweeter to get it to integrate with the rest of the design.

So to me having an AMT tweeter is no mark of quality, and I think the same for other types of drivers. It's the final execution of the driver itself, and then the speaker and it's environment.

Best,

Here’s another example of how different similarly named or looking tech can be. Look at comment #9 regarding the design of the prototype ribbon from Hi-Vi RT-2 for the Carver Amazing loudspeaker:

Let me throw in an unmentioned ribbon tweeter.  Newform Research produces a 30 in and 45 in ribbon tweeter.  This is a true monopole line source.  I have owned a couple of module 30's including an no holds barred model.  Different radiation pattern altogether.
