That depends on whether there's any consistency to this 10 dB difference among all users, or is it based on some particular aspect of the EQ curves needed for your case. If it's consistent, it makes it easier to compensate in a future hypothetical firmware update as a simple gain shift.
i'm not sure if it is firmware, i just spent the last 5 hours messing with mine and when i put my fronts to large and turn off my sub the volume jumps again drastically almost like dirac is off but it's not i need to turn it down to -25vol. and when i put the sub back on it goes quiet have to go to -5 ish to get decent sound.
my trims were -14 sub, about -9 for 7 main speakers, and -1 for my tops
i then reran dirac but turned the input dial on the inuke for the sub and it made trim levels that main speakers were -25, sub was 0, tops were -17
i then decided to try a 2 channel amp with xlr on the tops instead of my xlr-rca rotel amp this bumped the trim level up 6 db on the one set of tops
i bumped up the inuke some more, managed to get trims -11 mains, -2.4 sub, 0 on the tops with rca and -8 tops with xlr
my next step was to try only one set of tops so everything is on xlr
trim mains were -16, sub was 0 , and tops were -13
the last measurement i took after bumping the inuke up more
-5 for the mains -8 for sub and -1 for the tops,
i also reduced the voltage from 3.5 to 2.5, but lowering the trims to get them much closer made big difference on volume -30 is decently loud now
i haven't tried playing music and playing with the speaker sizes and lay out with this yet. it looks like i may need to get a different amp and run all xlr connections
