Hi all, I've recently bought a pair of AR9 & the 12" drivers need re-foaming.
I'm after some advice on what amplification might be needed to have them running properly? I have a marantz pm7200 but I've heard this might not be enough? Any advice would be appreciated please. 🙂

Hi.
AR9 12'' woofer is very similar if not identical to one used in AR3 family and later AR10pi and AR11...
So here comes some information. You have bought nice speakers.

I've got many different vintage models from AR and must say that all are good sounding. You will need at least some 100W for bigger ones. I use Phase Linear 700b with AR10pi speakers. Of course be careful with volume. Nice vintage pair. Don't expect same performance as modern speakers can offer but still very very good sounding and nicely balanced indeed. Happy listening.

hmm. I bought a pair $40 but sold them.
They had no surrounds left on woofs and most on one of the 8's.
replaced the (if I remember right) 8" mids (don't, refoam them, the poly replacements were absolutely awful).
Before replacing the 8's, I liked what I heard (without the woof, sub woofs).
But, if it was now, I'd refoam them in a heartbeat and keep them.
Maybe parts-express can refoam them.

Would anyone be able to help me with the schematics please & what impedance the drivers should be? Thanks
Just google... (if you know where to search) some of the links might help you, AR-9 crossover included in the end.

It makes sense, 8 Ohm nominal - 6 Ohm (but I don't know exactly how much).

Hi.
Any photos? If it is the unit with square magnet at the back than it is almost 100% original. It is very similar unit as one used in smaller speakers (like AR17,18,25...). I don't know if they changed that magnet later for roun one. It is also possible. If it mechanically fits it is probably original. Check some pictures.

Hi thanks for all the replies 🙂
I can't seem to add photos from my phone... 🙁
I have removed the lower mids & both are sound lab not AR! So I now need to try & source some 8" lower mids too. But looking at all schematics I can't find frequency response & what the originals whether 4-6 or 8ohm? Has anybody got a pair that they can help please?

Try to source originals but I'm afraid it's going to be hard one. But here comes useful link.

why are you replacing the original drivers ?
You are never going to get that great sound that they had.
Refoam them !!!!!!!!!!!!!!!!!!!!!
They needed a bit of power, but they were wonderful.

I'm repairing the 12" but I don't have the original 8" they have been changed at some point & I want a pair of originals to put back in.
What kind of power are we talking? I have a marantz pm7200 155w into 4ohms is that enough to biwire them?

Is it worth recapping the co while replacing the foams or recommend try them first then recap? Thanks for all the help so far 🙂
Going to jump in here; neighbor has a working set ar9s (re-foamed), but one of the tweeters is louder than the other.
I guess we can pull them out and bench test them. Are there any upgrade ideas; e.g. better tweeter caps?
That's some xo! I hope this is for both sides.
btw, he's using a active car xo and separate amp for bass woofers.
