My HT has been revamped and I went back to a 5.1 system. These speakers are just one year old with maybe 100 hrs and were installed is a non-smoking, no pet dedicated theater as the rear channels. My new layout does not allow for these to be included. I have enclosed a link form Paradigm. Please note that these speakers include the wall brackets Local Pickup is available. These are good speakers to round out a Studio or Millenia series speaker HT setup.
