It's a parametric EQ. Can be use to tune your sub or main speakers. Use REW to check out your speaker freq response in room. If you have a huge swing of more than 15db from 20hz to 10khz, you can consider the EQ to get a flatter response. The only thing to watch out is make sure your speaker and sub had enough headroom as EQ will cut down your maximum output. Not that this is a problem for your submersive.

Think of it as Audyssey but manual tuning. I need the EQ as Audyssey MultiEQ XT doesn't work properly in my setup. Also you need a power amp as the BFD sit between the receiver and the power amp.
