Tad drivers vs JBL drivers

[grumpy]

Everyone's guessing a bit, until they have one in hand.

[Guido]

my understanding is that the compensation built into the
network itself would likely need to be adjusted to account for the
higher level of HF response from the Be diaphragmed driver....

Exactly!

As long is I don't have the 1,75" Be dias on hand I can't say how the new compensation looks like.

Well said

I will know it first hand when these dias are available and I'll report.

For those who are interested I had this reply back from Brush Wellman yesterday ...... Quote ...

"We currently have 4 inch diameter voice coil replacement diaphragms available and we are considering future development of multiple replacement beryllium diaphragms. One of the designs we are considering for development is a 1.75 inch voice coil diameter diaphragm that is compatible with a number of compression drivers including JBL's 2425/6. I anticipate that we will be deciding on a diaphragm design for development within the next few months and it will then be approximately one year before those diaphragms are available"
........ I can't wait ..... it will save me from having to buy TAD 2001's

I think you are going to find they are much further along in this process and they will be available sooner.

That will be excellent if this is correct, do we have any idea on prices yet? ..... any owners of LEAP interested in re-designing the crossover network for the 4430/4435

If you give us frequency response and impedance graphs of a Truextent 1,75" dia in a 2426 on a 2344 horn with pleasure

This sounds great?!

Excellent Guido co-operation on this site can be outstanding at times now all we need is someone with Clio and the spare time and the willingness to assist

This was meant as a joke

I'll have the 1,75" dias first as I'm a truextent dealer. So I gladly make the neccessary files. If I have the time I'll also make the compensation network. It will not be before summer/fall 2011

Ahh ... the problem with the written word over the spoken word, all inuendo is lost

Anyway, there is still my promise.
Remind me if I forget it. Please!

You bet ya .... you might end up being the biggest mover of these diaphragms
