How long do speakers last before their performance begins to deminish significantly?
I'm a big fan of expanding the financial reach of my audio spend where possible by investing in good condition used equipment. I'm less concerned about solid state amplification in terms of longevity, as I assume a good solid state amp will provide years and years of good performance but speakers, with their moving parts, I'm more concerned about. If I can get a 3-4 year old used (but current model) speaker for about 1/2 the retail price, is it worth the savings? How many more years of optimal performance can I expect to get out of, for example, a 4 year old pair of ProAc Response D38s?
Thanks in advance for your input!
