    Allan.
    Thank you Allan! That is too funny. They are in my backyard. I can be a lot of help to them as a corporate banker and fellow audio enthusiast. I'll call them today. Their website isn't super helpful about my question however. Did you just source your diaphragms from them or do they mftr the whole Compression Driver????
    Thanks,
    Paul

    4313b was using 476Be drivers, there is a pair for sale in the marketplace for $6000 plus shipping from Europe. The genuine JBL 4" Be drivers are sort of expensive and also hard to come by, so most mere mortals opt for TruExtent 'phragms in pro drivers.

    It's been awhile since I looked, but at one time TruExtent made diaphragms to fit 4" voice coil "pro" drivers. For JBL, something along the line of 2440, 2441, 2445, 2446, 2447, 2450, 2451, 2452, 2450-SL. The TruExtent Be diaphragms were to be replacements for pro audio (think PA, concerts, clubs) applications.

    In 4" "home" drivers, you are looking at the 476Be, for example. I doubt the TruExtent 'phragm would fit that driver, and you probably wouldn't want to try. Again, it's been awhile, but at one time it was not an easy task to buy the JBL "home" drivers by themselves. Some did, but I think it was more complicated than calling them up with a credit card number. That might have changed since then, call them up and see I guess. But you can buy 4" "pro" drivers fairly easily and install a TruExtent Be diaphragm.

    TruExtent was looking at making Be 'phragms for the 1.75" voice coil drivers at one point, but I don't know if that ever panned out. JBL also makes some 3" coil drivers like the 435Al and 435Be, but now you're back to "home". I think Harman was selling the 435Al/045Ti/horn/crossover combo at one time through Synthesis dealers, you might see if they'll still do that.

    Thanks Jeff,
    I visited VUE and bought a couple of the Be diaphragms for my 2446's.

    So now I have a TAD 4001 and the 2446 Be's. Any idea which ones will sound better?

    to 10lHz, I believe 2446BE woulb be good, but 2405 would ba 'a must' over 10kHz.
    no idea about tad4001

    Would you mind posting these many details? I'm excited as child. That would be a big help for many of us, thanks a zillion.

    This thread has been dormant for two years so the likelihood of an answer is low, that said going with the SAM 1HF has been the route most have taken.

    I've been busy with friends who have medical issues but not forgotten 1501Fe/2206J/2447 on 2332 horn system. I hope to get back to audio again soon, I miss it!
