TheLion, this topic is complicated for you because you're doing bass management with convolution filters. I think the convolution filters should understand that when they add something to the subwoofer channel, they need to do -10 dB on what they're adding.
In other words, I'd make the signal still expect a +10 dB boost to the subwoofer when coming out of convolution. I'd do this +10 dB boost (replace +10 dB with the actual decibel measurement) with Room Correction.
mojave is suggesting you turn up the gain on the amplifier for the subwoofer. This is good when it's possible, but it's not always possible. For example, I use the same amplifier for the subwoofer as the other speakers, so I have like a 30 dB swing (with Room Correction) between the center and subwoofer channels.
Matt,
I understand your point. As you know I am using Acourate to do my filters for convolution. All my filters are "normalized on a per channel basis" (each channel filter has the frequency with the least required attenuation at 0dbFS digital level) - so I need to use Room Correction for setting relative channel volume instead of doing this with convolution. Your suggestion with making the convolution add the low-passed speaker mix at -10dbFS to the subwoofer output channel is completely correct (= the same as adding +10db to the LFE channel). But how can I do that? Only way to do it is by adapting the configuration file. Mine is:

The last four lines are for the low-passed speaker channel mix. Which parameter do I need to set there in order to make your convolution engine apply -10db to all summed low-passed signals?
Thanks for your support! (although the question turns out to be a little off-topic ;-)
