Well, they are certainly worth more than $60, assuming all drivers work. It's rather funny reading the description. Those "subs" are of course actually woofers, and when he references "horns" I'm sure he means tweeters. I'm not aware of any CV ever using horns.
I'm assuming you know Cerwin Vega and what they are and what they are not. But $60 is a steal if there are no blown drivers. CV's have a following and they sell well. The ones you are looking at could easily go for $200 or more, maybe even cracking $300. Better grab em.
