Nothing has changed over the years. Speakers are mostly interchangeable things where you have the same old parameters that you have checked for many decades. Did you need a refresher course on Ohms and Watts? Sorry but it's all been beat up before so tell the forum what you really need to know. And no, no one can guess if these will be fine. The details of Ohms and Watts is not given (by you) for the old and new system.
I have an old Sony DAV-C900 home theater system and the receiver is getting ready to give up the ghost. Rather than buying a whole new system I was wondering if I could just buy a new receiver and use the DAV-C900 tower speakers I have with the new receiver. I know the speakers have plastic caps that fit into the back of the Sony receiver and I was wondering if I could cut off the caps and strip the wires and use the speakers with the new receiver. Thanks for any help and advice.
