I have a room that is 12X13X10. I get a huge bass peak at about 45-50 Hz and 75-90 Hz, my dad has a bigger room and gets the peaks at other Hz. I tried to place my speakers in different locations, but hardly got ANY change. Is there an answer outside of filling my walls with lead (seriously, have an uncle who did this), or tearing down the room and starting from scratch. It seems that all walls will increase the frequency at some point, so I guess everyone has this problem and just lives with it, or is there an answer???
