Looks Good. But whats the diff between these and ert26?
To my knowledge, The ert is a simply tweeter designed for a high crossover point to a wideband mid - to push the crossover out of the immediately audible range.

The LD25X is a modern day long throw tweeter than should handle a lower crossover point in the teens; allowing for a smooth driver transition at the crossover point.

Why is it partner with wide ranger? To accomplish 1st order filter for smooth transition? Cone breakup is the main concern here, if any to achieve good performance.

Will wait for more test results

Cheers

Re: VWR126X Mid Woofer and LD25X Silk Dome Tweeter Preliminary Info

You fine gents have pointed out some of the design reasoning behind the tweeter.

What can be one of the greatest reasons is the same thing we all think about when we look for subwoofers.

Volume displacement equals greater sound pressure level.

So why is that of interest in a tweeter?

Well in a proper design it should allow lower levels of distortion. That is definitely the case with the LD25X. Greater volume displacement means that the maximum spl generated off of the tweeter will give you greater headroom. A big plus when you are trying to develop a high end speaker system.

A not to often quoted specification in tweeters is maximum SPL and distortion figures. Soon to be released!

Re: VWR126X Mid Woofer and LD25X Silk Dome Tweeter Preliminary Info

Beyond pure performance information, it is necessary to design a tweeter that will last. Remember that the vc leads need to flex, though just a small amount, at least 100 times as much as the woofer, even more than that compared to a subwoofer. Every time the vc lead flexes, that is just a little more toward its fatigue failure. It would seem that the longer throw tweeters would flex even more shortening the life of those tiny and frail leads.

Or not. (Just echoing the concerns of a couple of others.)

Any news?

Lots.

They have been tested to the point of astonishment on my part. I can say unequivocally that these two drivers are in the top two or three of their type in the world. They have some of the lowest distortion widest and smoothest frequency responses I have ever measured.

So what you waiting for?

Last level of verification. This is being done very carefully. All will be revealed when the big guy is ready!
