jimmm18 Well Ive done some listening with the baf set to your code and it is working better than when it was set for the 801. Ive noticed audibly that the bass responce is extended with the baf. I have not tested with a meter but plan to.The only way audibly was with a disc that starts real low around 15htz and gradually goes up. The speakers responded quicker with the baf ingaged. (I have it in a tape loop easy to switch back and fourth) Also it did so at a lower volumn level. Another way I knew is because in this frequency I could tell by the resonance. My Home can not take alot of low frequency levels well It tend to rattle the windows and such. This happened at volumns with the baf engaged that did not occur when it was not. But most of all I liked the fact that my mids and highs were not compromised. Im a purist so to speak and I was really skeptical putting my source through another unit. What didnt you like about the baf. I never heard the matrix 804s. I heard the nautilus. (I still havent heard from b&w they definetly have the worst customer service I have experienced in this industry)
