Looking for 10 inch 16 ohm woofers for Beveridge

Hello fellow music lovers

I am looking for two 10 inch 16 ohm speakers as replacements for Beveridge Model III. Would it be good for them to be Aluminum cone? Would it be good for them to have rubber surrounds?

Thank you
You can still ask Rick Beveridge as I understand things. He has inherited the company and is available for help.
Otherwise there are speaker replacement and DIY speacialty retailers like Madisound that may have the driver you want.
