| Re: Equalization of TC-2000 sub.
Given your capable mains I would usually go with the 60 Hz (never 40Hz), but you do indeed have a peak at around 70hz likely caused by the floor to ceiling measurement of ~8 feet. If you use 60Hz as a crossover, the mains (which will suffer from the same resonance) might overwhelm the mix of the sub and main, and the peak might be tricky to get rid of. You could try it though at 60Hz and see how that goes.
If 60hz is a problem, then go with the 80Hz and see how that works out. I suspect it will be easier to get a smooth overall sub + mains when you're done using 80.
Man, your sub and room are some hot below 25Hz eh? Whew... The BFD will reduce that peak fine though...
Start off and eq the sub and then add the mains and try and match the level somewhat with the sub a bit hotter. Then play around with sub phase, sub receiver timing and filters to smooth the cross area (whichever one you choose 60 or 80)
