I realized I posted this is someone's else thread by mistake (sorry). I think I have finally found my speakers to replace my SDA 2's the ex destroyed. Although I have always loved the SDA's I truly am not as experienced in them as most of you are, so I am reaching out for alittle help. I found a pair of SDA 1's and SDA 2's in Baltimore. I am heading down on Sunday to hear them and possibly be bringing all 4 back. He is asking $500 for all 4, and mentioned that maybe 4 of the 6.5 drivers may need to be replaced. Other than condition is there anything else I should be looking or listening for? Any and all help would be greatly appreciated.
