They got me, because the top and bottom caps seem to be glued and you cannot roll the sock down. However, they have a 5.5 inch woofer -- 1 inch soft dome tweeter -- 2.5 inch rear firing woofer -- 12 db octave crossover. And rated 60 hz to 21 khz and 4 ohms. On a side note, I use to own some in the past and I did open them up -- however, I could not put them back together.
They were sold for parts only -- however, he said that he tested them with a small low level RadioShack amp for a short period and that the sound was clear, and he could not guarantee that they would hold up. But, that was a sign for me that they should be fine -- and they are. Under $55 total with shipping.
