Hi can anyone tell me vintage of these and are they mismatched? HWO 32P486 and 34R745 Worked in an audio store in high school and these and the JBL 100 were the top tier speaker. Found these on ebay locally and they are in mint condition with all paperwork and warranty card not filled out. Enjoying them already but would like to know what I have if future upgrades/repairs are necessary. THANKS!
