My AV system is set up in a large irregularly shaped open living room. I found that walking around room with music playing helped me find the bass nulls and peaks. Changing my listening distance from speakers significantly affects bass response. Moving my speakers just a few inches closer together made a big improvement in my room. A bass trap in the corner of the smallest part of the room was also an improvement. A new stiffer floor help also helped as did my 100lb sand filled speaker stands I built. Jim Smith's Get Better Sound has a lot useful information on this subject.
Budget Strategies forTightening up Bass?
My system: Opera Consonance 120 Linear CDP, Extensively modded Jolida 302B, Silverline SR 17.5 monitors. AudioArt Speaker wire. Various IC's. Short of buying a sub, what is biggest bang-for-buck upgrade to tighten bass? Wire? PowerConditioning? ("currently" I have just an upgraded cryo-treated outlet) Better footers? (I have vibrapods and cones). I've got about $350 to spend on this... I know-- that's not much-- maybe my goal and my budget are mutually exclusive. Still, any suggestions would be appreciated!
