Speaker installation
DR,
Hang on a minute. The Phonix Gold and Dayton speakers are in-wall and in-ceiling speakers. This means you cut a whole in the drywall to install the speakers. The in-ceiling version has 4 dog-eared tabs that secure the speaker to the wall. You can't just hang these in the corner external to the wall.
If you want some small (enclosed) satelite speakers, look for the Athena Micra 5.1 speakers. IMHO the phoenix gold in-wall/ceiling speakers w/ 6.5" woofers, 1" tweeters, etc. Would be a cleaner installation and will sound better than most small satellite speakers in your budget.
