I just had a neighborhood garage sale, and got two mint Sunn 15" speakers. I looked them up and they are 225 watts at 8 ohms, then 400 program watts? whats program watts?

Also I got them for $15 for both, I see on Ebay they are selling a pair for $199 and $500, what are these worth?

Program is basically the most they'll take, they'll do your 225 watts comfortably but if you get a spike of 400 watts it's basically what they'll handle before they go bang. It does not mean you can continuously run them at 400 watts.
That's my understanding of it anyway. Could be wrong.
