Hello! I had a few rowdy party guests over and while some music ended up being played over my system (7.1 Klipsch Rp with r-115sw) Someone drunkard "accidentally" turned the volume to full blast for about 5-10 seconds. The speakers are all powered by an Onkyo TX NR 787. Is it possible that this could have damaged them and is there any good way to test if it did?? OH I'm also looking for a secondary r-115sw if anyone knows of any direction to point me in for that! Thanks for any help! Stevce
