Just moved into a house that the previous owner had wired for a home theater. We already have a nice system, and I'm looking for inexpensive mounts to hold my 15lb. speakers on the ceiling. There's some nice mounts available from several vendors, but they run in the $50 EACH range.
I've thought about using the mounts that come with many of the outside flood lights. I'm sure they'd hold the weight, they're reasonably small, inexpensive, and flexible enough to work.
If anyone else has any suggestions, I'd love to hear them.
