Hi guys, I just got my Kenwood Fineline HTB-610 Home theater up and running and overall I like it. However, the I'm having an issue w/ the 6.5" Sub. I was watching Lord of the Rings Return of the King in Dolby D and the Sub had some bad distortion at times. It sounded like the woofer was maxing all the way out and the sound was awful. I had the reciever on about 25DB, but it does it at 30DB also. I had the Sub DB level at 0 on the Reciever. I did have the volume control on the sub turned all the way up, but it still did it w/ the Volume on half way. The Kenwood Reciever is a 500 watt reciever and the sub is 100w. It is a single rca hookup from the sub to the reciever and I have a Monster cable sub RCA running to it. Other movies don't seem to cause the problem. Was the bass from Lord of the Rings to deep for the 6.5"? It's frequency range is 35hz- 200hz. I'm already thinking of upgrading to a larger more high quality sub.
