    I've tried the THX website plus the Denon website, and extensive searches on here and other forums to try and find some detailed information on how BGC works.

    I have the Denon KAVCA1SE and have a boomy bass peak at 50Hz. I have a BFD on order after reading about the great improvement the unit has made to many people's setups, but was wondering if someone could elaborate on BGC, as I do sit near the rear wall. The scant information I have seen claims that BGC reduces boom for near-wall listening positions.

    Does it do something clever or just reduce overall bass output?

    After checking with a Sound Meter and AVIA, all it seemed to do was just reduce output below 50hz. I actually had 10db less output at around 20hz with it switched on so I´ve left it off.

    Hmmm I suspected as much. Thanks Jase, looks like the BFD will be the key to taming my 50Hz peak without detriment to sub 50Hz signals then...
