I have a SPL meter I just got yesterday, and just ran a 10hz-300hz Test Disc someone sent me a link to, to burn. It spikes all over the place, with a few noticeable peaks. Biggest problem exists around 42hz where it peaked at 97db and by 50hz bottomed out at 72db. Another low point is at 120hz and the rest goes back and forth between 84db and 93bd. So where do we go from here? Is it time for an EQ? To be honest I have been a Car Audio man for many years and run an EQ in that system, so an EQ is the first to come to mind here. Whatcha think?
