[QUOTE="Timber_MG, post: 698850, member: 18"] You'll get some solid advice on this forum, likely better than some acoustic treatment salespeople and installers may give you (often they're limited i.t.o products they install). Hard surfaced rooms like a cellar require the correct approach as it's easy to make it worse while spending money. One measurement you're after is RT60 in octave or 1/3rd octave bands. It's an indication of how long sound takes to decay by 60dB over frequency and is easily done in a run of 5 or so measurements. One goal is to get the decay as even as possible and at a time constant that suits the purpose of a stereo listening room. Room EQ Wizard is freeware software and the RT60 measurement can be done with any microphone (Audyssey receiver jobbies work quite well). You will even get an idea of the resonances but to get relative levels (not only where and how deep the peaks/troughsbut also their relative levels) will require a good microphone (calibrated preferably).
