Im brand new to the forum and recently bought a set of ESS Tempest LS8 at the Salvation Army for $7.99 per pair. I was not able to get any history or information on these via my mobile phone , other than they are from the 1970s and the tweeters apparently were very nice. My ears tell me they were at one time of very high quality, but these ones will need new 8" drivers and new passive radiators . I'm wondering if these LS-8s are worth the time and money ? What kind of replacement drivers would be the best choice ? And What kind of sound quality can they actually achieve ? Thanks , James
