Buy them! You may have seen my $200 Dynacos when I first bought them...
Also in rough shape, but remember...
New grille cloths can be bought or made...Foam surround kits can also be bought...and reasonably!
Mine were worth every penny and are in my main system!
Soooo, my advice to you on the Advents is...BUY THEM!!
YOU WILL NOT REGRET IT!!
Read the reviews and you will see...https://www.stereophile.com/standloudsp ... index.html
Both of our speakers were considered "best buys" then and I'd say BEST BUYS NOW!
But, I would NOT wait long...They are bound to get snapped up by someone quicker than you, and if I were you, I would NOT let that happen!
Besides, if you run into any trouble, you've got plenty of Engineers here in your corner!
