Due to the noise setting one’s Spl (A+Weighted) delivers greater range. That’d conclude my personal belief. Strolling railroad "tracks" are not always intended for any specific individual during any given Tuesday, and engineering design flaws are indeed inevitable.
SPL Surprise!
Recently during a listening session, I got the idea to use my Radio Shack SPL meter, (C-weighted, fast response) and got a reading of 84 dB peaks at the listening seat about seven feet from the speakers. Curious what the reading would be closer to the speakers I held the meter a couple inches from the tweeter, midrange and woofers.
108 dB at the speakers!
24 dB difference over a distance of seven feet.
Wasn't expecting that much difference.
