+1 @dekay I had a pair of old Radio Shack Optimus 1s with cloth surrounds. They dried up and became stiff so I think that would be the main issue with them |
ALWAYS go with the original material, the surround can be considered like the suspension of a cartridge's cantilever, CONTROLLING Movement. My vintage electrovoice 15" woofers from 1958 MUST be cloth. Last much longer: To alter the response, more than likely detrimentally for every day of their longer life is a 'wrong' decision. Paper lasts a long time, the original surround for that size cone is likely to be around for generations! Avoid any hvac heat discharge nearby, shut that vent to prevent premature aging/drying of the paper. Very dry house, get a whole house humidifier or if radiators nearby, add water gizmos,
