Default Tweeter / Mid Upgrade for Vandersteen 2CE

I have already upgraded the 10" "coupler" drivers on my Vandersteen 2CE's and I'm looking for suggestions for a soft dome tweeter and 4" mid range that would be a good match to the Vandersteen crossover. I'm not familiar with matching drivers to crossovers or if that's even a concern. My priority is the tweeter, years ago I built a pair of speakers using a wonderful doft dome that was made in denmark, I believe it was a scan speak. It portrayed the most realistic cymbal with wonderful decay. This is what I'm looking for, any recommendations?

Thanks.

Hi, not a good idea, you will be guessing, that is never good, rgds, sreten.

Can you elaborate as to what I would be guessing? What are the critical parameters in a tweeter, sensitivity? resonant frequency? Obviously I don't need to worry about cabinet volume and so on. I am not very experienced with crossovers so I would appreciate some feedback as to why it would or would not work. Here is the Vandersteen description of the stock tweeter;

TWEETER:
1" critically damped metal alloy dome
Dual-chamber design
Ferrofluid voice coil cooling
Range of operation: 5kHz - 30kHz

Here are a few I am considering
Morel CAT-308
Morel MDT-30S
Usher 9950-20

You're guessing because crossovers are designed around drivers, not vice versa. There could potentially be a lot about that crossover that's in place to correct and mold that particular tweeter, so changing it is a compound issue.

If you can find one with exactly the same Fs, same impedance curve and same FR, you might be able to get a good match, but it's hard to know.

I would probably take the 2CE crossover and reconstruct it in Speaker Workshop, that way you can see what your potential drivers are going to do with it.

If you could find out what actual drivers the Vandersteen uses (from memory it's Vifa) then you could look up their specs and then find a driver that is a close match.
You will need to match sensitivity, impedance, resonant frequency and frequency response.

Otherwise you are just guessing and would likely degrade the performance.

Hi,

You are wasting your time. I'm still befuddled as to how you "upgraded" the
rear 10" "couplers", as the originals have a huge lump of MDF glued to them.
(And I know why, anyway see the various stereophile.com 2C reviews.)
I doubt you've actually made them any better, almost certainly worse.

You don't know what your doing, so leaving them well alone is sensible.
I do, and I'd never consider "upgrading" the drivers in such a design.

rgds, sreten.

There was no huge lump of MDF glued to the factory 10" coupler (?). Actually what happen was, the spiders in the original couplers failed so I took them off to a very reputable speaker builder / repair co. and he was quite familiar with the driver, he gave me two loaners to use while he performed the repair, he commented that the loaners were a much better driver for the application and he was right, the bass was much improved so I decided to purchase them as the replacement for the originals...

Certainly not a waste of time.
