I purchased a pair of Studio Montior 120 used from my brothers friend about 20 years ago which have always (when in my possession) been powered by a Bearnig TF-10 preamp and a Dynaco ST-70. I admit that I have cranked them up from time to time (who doesn't) but it seems that the bass response has diminshed over the years. After I restored the Dynaco I began to look into the Infinity's and found the speaker surrounds are falling apart. I have cleaned the tweeter and midrange control pots, and both tweeters and midrange sound fine. I believe that the tubes have protected the fragile traces as discussed in other posts since tubes get "dirty" but do not clip like SS when pushed to the limits of sanity. Finally the questions: What are / were these speakers worth? What cautions should I be aware of when I get into replacing the surrounds on the polimer cone speakers? Any other tips, I want to keep these speakers, I like the look and the sound (I realize there is better out there but this is what I have.) Thanks, Dr Olds
