These speakers were manufactured in the late 1970\'s and have a good sound but I would like to attempt to improve it with upgrades. I own both CM-1020\'s & CM-1030\'s. Does anyone have a service manual? Does anyone have any information on or know anyone that has upgraded the crossovers or speakers?
Jennifer. I can help. Send me an email message to email@example.com. I will then contact you from my real email address. I own three (soon to be four) pairs of CM1030\'s and one pair of CM1020\'s. I only check that email account every couple of weeks (it\'s for diverting junk email to - if you did not notice) so it might take me a while to get back to you. Regards. Jeff
Hi did you ever get a service manual for for the CM 1020.If so can you send it to me. I got problems with crossover and swiches. Thanks, Dan.
