Illuminati (33rd Degree)

Just a reminder: I think you're getting pretty usable information from your test setup but remember that it's tough to get really accurate information from a Radio Shack SPL meter. The resolution just isn't there. And indoors, you're measuring the room more than you're measuring the speakers. Even measurement systems with time gating are limited indoors, because reflections are too early to gate out. This prevents accurate measurements below midrange frequencies indoors, even on the best measurement systems.
