not sure what you mean by "rolled off low end response".
In my LLT Explained thread, look at the three different FRs I posted near the end of the 1st post. One is tuned too low and the response rolls off too much - your proposed 11hz tune in 550 liters would look more similar to that than what I would considre the ideal response to be. Room gain typically yields 4-8db/octave, so you don't want the shaped FR to rolloff any more than that until below tuning.

I planned on using the bfd to roll it off gently after 60hz and then cut it off harder with the reciever/computer at 80-100hz.
In an attempt to achieve what?
