I have a CS - Ultra with the samson 1000 watt amp that comes with it. I have just moved a couple times in the last year and i have new speaker arangments. My speaker levels including my subwoofer are all the same and my subwoofer still sits in a corner. I have been watching movies at volumes i have watched before and i am seeing my amp clipping. What is this clipping caused from? Is this bad for the amp or the sub or both? My main question is why is the amp clipping now at volumes 5 to 7 decibals from reference where i have played before with no clipping? For instance i was testing Toy Story 2 and the Haunting yesterday and i used to get 116 spl out of the Haunting at my old house with no clipping at about-2 "volume" on my B&K AVR - 507. Now with my speaker lvls exactly the same I am getting clipping on the haunting at or around -7 volume on my receiver and getting 112 SPl. I understand that different rooms will get different SPL but why is my receiver all of a sudden clipping on volumes it used to handle so easy. I have all speakers calibrated at 75 on my SPL. ALso my sub is closer to me now then previous rooms, about 10 or 12 feet away.
