I like 'em. Basic 3-way JBL bookshelf from the mid 70's with a 10" woofer. I've got their little brother, the L-26, same thing but with no midrange connected to my Marantz 2230 of the same era. Hard to beat when playing classic rock in it's native format.
If they are in good shape, I'd strongly consider it, but I know what they sound like. You might not.
Now, for HT, might want something a little more modern with a matching center channel, surrounds and more power andling capacity.
