I need you all to check my logic on a couple of things regarding implementing a housecurve. Once I have set my BFD filters to produce the house curve, I do not believe I can simply use subwoofer pink noise test tones to balance my sub against my mains. The housecurve makes one end of my frequency response louder(that is it measures louder) than the other. The pink noise test tone is made up of all the frequencies in the bass spectrum, so when it plays, it will measure at the SPL of the loudest part of the spectrum. If I use my test tones to set my sub level equal to my mains, I will be setting the mains to match the SPL of the low end of the bass response (because this is playing the loudest), when in reality I want it to match the high end of the bass response (where it crosses over with my mains). For example, if I have a house curve that offsets the bass response by 10 decibels from 30 Hz to 80 Hz and use test tones to set the Sub pink noise SPL to match the main speaker pink noise SPL (say 75 dB), then I will have the sub playing at 75 dB at 30 Hz, but playing at 65 dB at the crossover frequency (10 dB lower following the housecurve). The mains will be playing at 75 dB. Am I correct?

So, what do you do? Do you just set the Sub level using test tone pink noise and ofset the sub and mains by however many decibels are included in your housecurve? Or do you use REW and continue to measure and adjust sub level until it looks matched at the crossover point?

Second question. I have heard people saying that you can use your BFD presets to have a couple different sub responses. One preset can be used for a flat response and another can be used for a housecurve. That way, you can just switch from one preset to another to change your room response for movies or music. But, if what I said above is correct about matching levels, then if you set levels using a flat response you will be down 10 dB at the crossover when you switch to a house curve. And, if you set levels using a house curve, then you will be up 10 dB over the whole bass spectrum when you switch it over to the flat response. Again, am I right in my thinking here? If so, then it makes the process of switching between flat and housecurve more complicated since you would have to re-balance the subs and mains everytime you switched.
