What is the general consensus regarding room response, particularly in the bass region; is flat response the goal, or is in some amount of boost in the low end normally desirable? Is truly flat response across the whole spectrum really something that is pleasing to listen to, or is it merely a starting point?
I have gone through a fair amount of trial and error in order to arrive at room bass response that, in my room and with my ears, sounds authoritative when true low bass is present (read; I can feel it in the couch!), yet does not normally sound boomy (some content does require some level adjustment of the sub). That said, it is NOT flat, but rises gradually from about 80 Hz and below, peaking at about +10dB at 25 to 30Hz relative to frequencies above 80 Hz.
Now, to be clear, I don’t consider that there is any problem per se, in that the system sounds great to me, but I am curious if there are those that do run their systems set for flat response, or if the consensus is that some amount of low end boost is usually needed.
I use an Audio Control Bijou (1/6th Octave control below 80Hz), and have taken measurements with various test devices including SpectraPlus software with a Sure SM57 mic (using a compensation curve for this mic), the venerable Radio Shack SPL, and now with the Infinity RABOS SPL meter (which BTW, is quite nice for measuring and graphing low bass response, even without Infinity RABOS speakers).
The room response was tweaked to be reasonably flat in the bass region (
