[QUOTE="audioholic, post: 7665672, member: 549629"] First, I hope you didnt think I was implying you shouldn't ask this question, that's what this forum is all about. How close to the wall the sub is will affect its perceived freq response, as this will alter wave reflection, cancellation nodes, etc. Usually you dont want to be any closer to a loading surface than half the diameter of the port, or double the excursion potential of the cone. Much closer than this will tend to suffocate output. But this also depends on the angle of the surface, if its a flat wall or a corner, etc. The best thing you can do is educate yourself on the topic a bit (by making threads like this, research, etc) to get you into the ballpark, and then do as much testing as is feasible in your circumstances. Unless you are a hardcore SPL or SQ competitor, this method will usually yield less-than-ideal but more-than-adequate results. I know Im not being very specific, but I hope Im helping anyway.
