The problem is more so with one, but exists in both its a humming sound that is quite noticeable. the speakers are R20 roughly 4 years old, connected to HK AVR 225. If i have missed something, please let me know......
Thanks.

Sounds like a ground loop. Do a search on ground loop and see what you come up with. Have you added any new componets recently? If you disconnect them does the humm go away? They can be a pain to trace down, but are worth the effort.
