Welcome to the Forum!

Tomorrow my Visaton B200 arrive and i already have baffles for them. Will this lower damping integrate with OB? Or am i forced to keep it at high?

What’s a Visaton B200?

Another idea i had since i only use 1/15th of the power of the amp i could just cut ~10-15dB and make the whole graph ruler flat (eliminating 60Hz dip) and just turn the gain knob on the amp way more.

How would you do that, since you don’t have an equalizer? Turning down the amp’s gain won’t fix that 60 Hz depression.

It's kind of redundant to Bass Boost 14Hz on the amp and then cut them with BFD. Will it compress the dynamic range?

If by that you mean “Will I loose headroom,” the answer is any equalization exacts a headroom penalty, so you have to have enough to spare going in. It appears that you do, based on your “1-1/15th” statement.

FE167E seems WAY too bumpy (look at all the +-10dB hills) considering i copied Bob's design word for word and his response is much flatter +-3.5dB.

The only way to duplicate Bob’s figures is to use the same measuring technique with the same measuring instruments and equipment in the same environment he measured in. Change any one of those and you won’t get the same results. What you’re seeing there is room interactions, coupled with the response of the mic you measured with. I’m not sure the CM140’s mic is accurate all the way out to 20 kHz. Did you use any smoothing? That will make a difference in the way the graph looks.
