The Fathom 113 is the best sub that I have ever had not to mention that I have demoed in my HT. You are right about me being bass crazy. But this venture to adding another subwoofer is only a thought not a piece of equipment that I will be buying soon.
The next piece of equipment is Blu-Ray....MAYBE. I still need more info. Not only the best bang for the buck but also something that will not be outdated the minute I buy it.
