Tweeter quest


Dear All,

I heard a really good ribbon tweeter over the weekend. Its spurred me on with an idea I have had for some time - namely replacing the vifa tweeter in my pmc mb2-xbd-a with something of the standard of the rest of the drivers. What ribbon units would people recommend as being the best around? In addition what are the pros and cons of ribbon v. electrostatic. What are the best electrostatic tweeters currently?

So far the following have been suggested:

BG NEO3-PDR PLANAR TWEETER w/BACK CUP

Raal 70-10

Yes I think they need to match - I was looking at one of the hivi isoplanar ribbons perhaps as they are more like conventional tweeters in shape and dispersion.
Hi,

I am not unhappy as such - the supplied tweeter is quite good. However a ribbon might be much better given what I have heard recently. I wouldnt modify the front baffle - so I could just swap the old tweeter back in. I dont really think there is anything to trade up to - the pmc bass and midrange are peerless.

Hi,

The speaker is active so I can do it all in the electronic crossovers. I have room measurement equipment and software and a couple of guys on hand that design there own speakers and can help me out with the upgrade. I beleive info on the existing tweeter is in the public domain as well according to my contacts. I would crossover at 4khz.

What do you think? Any recommendations for reading?

Regards,

Nick.
I would mount the unit via an adapter plate to the existing screw holes so it would be completely reversible. I would keep the original tweeter. Apparently the PMC uses a modified audax tweeter not vifa as I originally stated in the active speakers - apparently the bbc loves it.
Volt radial bass driver and PMCs own midrange.

Yes I might use the deq to help out as well.
