So I guess what your saying is that by putting of "room treatments" will not really improve sound, but make it worse? Someone told me that my sub is already overkill for that size room 15x9 a SVS 25-31pci. If I could find a way to make a graph of in room response, I will post it and see if anyone can give any info. The main speakers are just bookshelfs M2's right now, so I just need to smooth out the freqencies below what the M2's are capabiliby of, I have them set for 100hrz cutoff with the sub cut off at 120hrz, but the 50-70hrz is drasically rolled off to almost inaudible levels using DVE audio test 15-300hrz.
