If you have a fairly big house, or you used to be in the artillery and like
your musice REAL LOUD.

Old rockers, too.  I had a pair of A7s for PA speakers for one of my bands
about 35 years ago.  I used 'em for HiFi at home.

Altec quotes $300 shipping, each, so you certainly want local ones.

Well, they had cabinets.  Plywood, spray-painted any color you wanted, as
long as it was black.

Some of those Altec custom cabinets were really, really nice.

It doesn't take much.  I see the spec sheet at
http://www.alteclansing.com/legacy/specs.asp says the new ones are rated for
200W, but I think the ones in the Sixties were for much less.  The new ones
also have a 900Hz crossover, but I'm pretty sure the old ones had 500 or
800, depending on the model.  I'm also sure the new ones are much better
than the old ones, although the new prices are a bit on the stiff side.

On the old ones, 25W was enough to run you out of the house.  Those are
_very_ efficient speakers, especially the bass-reflex-with-horn-on-top
model.  I'd love to have another set.
