so i heard in-ceiling speaker just not as good as normal bookshelf speaker mounted on ceiling and point at MLP, is this true?
That would depend on the speakers. The
best bookshelves are probably better than the
best ceiling speakers and of course there are a lot more bookshelf speakers to choose from. I THINK I've seen some in-ceiling speakers with a tweeter that can be aimed.
i can't seem to find a good ceiling mount hardware for speakers. anyone know one?
That would also depend on the speaker and you 'd probably have to drill holes in it. You might have to make something or adapt something from the hardware store. Google found
these.
...My rear speakers are large (supposed to be floor-standing) hanging on the wall with chains, pointed down, near the ceiling above my couch. I drilled holes and installed 4 eye-bolts in the back panels.
