I mostly agree with this.
Hey, late to the party. I have owned the BFD for some time and yes it is a very nice EQ device for the novice. It's nice that it is all digital, has many filters, stereo compatible and has a very nice voltage range. It is nice for EQ'ing but like BassThatHz mentioned, it's limited.
Here's the biggie for this one: it has no controls for delay or high/low pass and these are essential for a proper sealed multi-sub system or any resonate system that requires a high pass filter of sorts. If you're lucky and own an AVR with discrete stereo subwoofer outputs you can get by possibly with using the controls for distance/delay.
So if all you really need is some PEQ and nothing else, it's still a good buy but if you want some versatility or something more advanced, skip straight to the DCX.
