Help with BFD (newbie here)

[Mattlock]

Just finished building my sub. Here's the specs
1) 690 liters, Sonosub (pic attached..sitting beside my SVS PB12)
2) Ficaraudio Q18 single voice coil, 8 ohms
3) Powered by EP2500 running in bridged mono
4) BFD 1124 (but not setup yet)

The sub sounds awesome right now...but want to make it better

Attached is a graph of my curve without the BFD...

My settings were 1)EP2500 Gain - max 2) Sub setting on receiver -5.5 3) Volume set @ -20

I'd like to get some feedback on suggestions for setting my filters...What would be a good point for my line? (newbie here so I'm keeping it simple)

Keep in mind that my theater is used 100% for movies...

thanks
Matt

Is that your sonosub only or does it include the SVS and mains also?

[Mattlock]

that is my sonosub (not PB12) and the mains....didnt know if the mains would be contributing under the crossover point...80hz

Can you provide a response of the sub alone taken from the listening position (using the standard crossover you like to use)..

Yeah, REW is really the way to go. The time spent learning how to use it will be worth it..
