I recently replaced my old Elite with x3500h and would like to use my two spare JBL 130 bookshelves as atmos speakers directly above the seating position (facing down). I have a 5.1 JBL studio 9 series + SVS sub config presently so the 130s will timbre match perfectly. My question is how to mount these 11-12 lb speakers on ceiling? I have purchased keyholes (2/speaker) and can drill screws into joist to hang these but need advise if there is something better than what I plan on doing.
Thanks!
