Hello everyone,

I'm in need of advice...looking to mount a pair of 8" surround speakers in drop ceiling tile above seating area. Most speakers are designed to be mounted in a baffled wall or ceiling using the space between stud and sheet rock. Will I loose sound quality by just mounting in tile? I will support them with brackets so they won't fall out. Any suggestions on Polks to get? Have a CS200 center and older set of RT8A's.....would also like to replace RT8A's with good pair of bookshelf speakers without spending a grand!!!
