Sorry, but I should have been more clear. I need replacement drivers for the Gradient SW-63 dipole subwoofers for QUAD ESL-63 electrostatics. Gradient used a pair of Peerless 831812 drivers per enclosure. The possible replacements - 831857 and 830500 - are no longer available, they are discontinued.
I am looking for affordable 12" drivers for dipole subwoofers.
Cheers,
