I have a AES paper on the 4430 It states the diaphram has a three dimensional diamond pattern suspension. The photo looks like a 2420 variant. But Im not shure.:blink:
2426 and i may be wrong but some of the earlier ones came with an alnico driver i believe a 2421 (dont hold me to that though)
Thanks, that was what I was hoping to hear.
I took off the 2235`s today, and looked inside the boxes, seing an alnico driver in there. And sat down and thought "isn`t this speaker design from the early 80s, and did they use alnico then?"
So for a while I was worried that it was not original drivers.
Thanks again for answer.
:) The first ones came with 2421A's, later 2425Hīs, I donīt think they ever got to using 2426's, but they are almost the same as 2425's anyway.
I always thought they used all three, 2421A, 2425 and 2426
If you've got 2421A's in there, be very happy. That'd be "first issue," and to me, the aluminum diaphragms are smoother sounding than the subsequent titanium in 2425/6.
Any time you want to give them up, I'll trade you straight across.... :p
I have replaced one of the 2425 h in my 4435's with a 2426. I had an extra 2426 h so I did not have to put money out for a new dia out at that time. I do not know how you can blow a 2425 in a 2344 horn without turning deaf, but I bought the 4435 that way.
There is no difference in regular listening as far as I do notice.
There are two ways.... three if you count electronics failure with some upstream device crapping out and sending a deadly signal to the speakers.Quote:

Right you are Mr.Widget But there is however a most common way of blowing them. Operator's error. I had my 2.5 year old turn all my settings to max. while not watching for a second.:Quote:

She managed to turn the system on, and was just ready to turn on the
" pink noise switch " on the Revox CD player. To high in the rack, no damage done.
I wonder how many " pro's " when tired went for that ?
And yes a blown amp with end transistors putting out 70 volt dc sends
drivers to recone.

witch model you have?
Revox B 225. Nice sounding player. Can not play some of the newer
CD-R, or CD rw. But makes up for that big time. I do also have some older
Proceed players. Same problem, yet nice. Thank's for asking.
