Can I put woofers from pioneer cs901a into a CS-63dx pioneer speakers
Do you really think you are going to get a lot of responses with a title like "???"
But what about that super tweeter sticking out of the center of the CS901a woofer? That seems like a definite complication.Assuming that the drivers are the same physical size a qualified yes. The speakers should however be matched for impedance, or the crossover will be messed up. They should also be of similar power handling ability and efficiency.
I've often repaired speakers for people by replacing blown drivers with replacements that were dissimilar to the originals , often with better results than stock (assuming that the replacements are better quality than the originals).
Speakers are the most subjective part of an audio system, don't get too hung up on details. If it sounds good to you, it is good.
The woofer in the CS901a woofer is crossed over at a higher frequency than that of the CS63dx so it should be OK to cross it over at the lower frequency. Without knowing anything else about those speakers my response is pure speculation.
You don't say if you are cannibalizing one set of speakers to repair the other or if you have access to those other woofers as replacements.
I didn't know about that, yes sounds like a complication. It could perhaps be left unconnected? Some pictures of the speakers would be helpful!But what about that super tweeter sticking out of the center of the CS901a woofer? That seems like a definite complication.
I did that with some Baby Advents, except I replaced the tweeters because I blew one in the pair. Completely screwed up the sound quality.I agree with keeping drivers original if possible. Years ago I was told to put different woofers in Advent speakers. It did not sound as good as the old drivers. We used to pitch the old ones and all they needed were foam surrounds. That was unfortunate.
We haven't heard back from the original poster but yes if the surrounds have rotted out he could simply befoam them!I agree with keeping drivers original if possible.

Except these don't have foam surrounds. Looking at the pictures on ebay. They appear to have the "doped" surrounds. Usually those don't fail.We haven't heard back from the original poster but yes if the surrounds have rotted out he could simply befoam them!
I've done 12 of the Pioneer HPM-150 40 cm woofers for myself and friends (see my avatar, X4), and if there was a sonic difference it was so slight to be imperceptible. Also I've done Advents, AR-3a's the newer '70s ones that came with foam surround woof's, and others I can't recall. No problem, and it keeps them as original as possible. YMMV!Refoaming can also alter the sound compared to the original foam and also to what it deteriorated to before it actually crumbled.
Cosmetically nice and solidly built old boxes are a great opportunity to upgrade. There are a lot more drivers available now than there were "back in the day".
