to all whom of which utilized the bfd to equalize their subwoofers....what is the preferred test tone cd to use in conjunction with the bfd? I finally hooked up the 1124p to my system and made adjustments based upon readings of the radio shack sound meter and personal preference via good ol' fashioned listening. It made a huge improvement especially on the lower/lowest end to the point where I was able to find things in my dedicated theater room that vibrated like never before. Those objects were eventually tended to and problem solved. I'm aware of the sound meter having value reading issues and am trying to obtain the correct values based upon my findings. I just want to better utilize the bfd for what it is capable of doing. My readings on the internet bring me to hometheatershack.com, but my main email is at yahoo.com and there is indication that requested info from them is difficult in obtaining due to their problems with sending that info to yahoo and aol and hotmail.com. I'm stuck for now, please help. thanks much.
