The last two days have been music heaven. I've been designing a tweeter (more of a mod) based on an industry work horse the Vifa D27 1" silk dome. People looking at it would say "that's a D27?" but actually I'm using only part of the Vifa that works fairly well with the design.
If you look on our forum you'll see that I've been doing tweeter mods for a while. Reason being there are parts of many tweeter designs that do things very well and other parts that once you become familar with certain characters and the why's of those characters it's hard to go back to stock again.
For years I've been trying to find a shop to voice according to my needs with regards to the tweeter and every time I would get a sample back something would be off and I would end up only going so far with the mod. 10 years ago I got pretty darn close to getting it but again couldn't get a shop to produce what I was doing by hand. arrgg, this was frustrating and would mean that I would need to do other things to systems to make up for something that I knew needed to happen with the tweeter specifically. It's a problem that happens with most tweeters on the market and designers work on making huge cross-overs to try to deal with it.
You buy a driver or tweeter and see foam on either the front or back of it. From a design point of view this is an attempt to fix a problem, and is causing new problems on many levels that don't need to be there. Look at it this way, the perfect speaker would be one where there was no cross-over required. A cross-over is a "fix it" tool and if there wasn't a problem there would be nothing to fix. You don't see a guitar using a cross-over between strings do you? What you do see are parts and pieces that are built to work off of each other when played.
Do this experiment. Take a guitar and play the bottom string, which is weird cause it's placed at the top most of the time. In other words play the thick string tuned to E. Tune all the strings. Play that thick string and listen to the harmonic structures and compare the sound of that string played when the other strings are in and out of tune. You'll notice that when the other strings are in-tune that thinker string is louder and more full than when the other strings are out-of-tune. There are other things to listen for, but the point I'm making is, the string works it's best when working with a vibratory network (support system). Your audio components work the exact same way, and your tweeter is at the top of the systems harmonic network.
If your system sounds bright and hard this means that the tweeter is either being fed a cluster signal or the tweeter is out-of-tune.
i have to run but will be back to add to this.
