mhuck123 Posted July 21, 2009 Author Report Share Posted July 21, 2009 Well we have been doing this for years and years.Build an enclosure with a flat response. A nice sealed box would do the trick. Play varying frequencies, dB Drag CDs have sweeps you can use. Use an SPL meter with a peak hold and whatever frequency hits the peak, is what you want to tune to. The Term Lab meter will be your best meter of choice since it reads the most consistantly and varying air temps do not effect at what frequency it will read more sensitive at. Also, the TL has an Oscope that will tell you at exactly what frequency was the highest SPL. This is really a 20 year old technique, and it still works well to this day. Thanks so much, means a lot coming from you Ed. My problem really is that I don't have access to the meter so I was hoping if I run the sweep with the peak hold on the Audio Control EPIC 160 would that at least get me to the right direction? I do wish I had access to a meter but not at the moment and the shops around here either don't have one or won't lend it out/let you use it. Quote Starting From Scratch!!

It will give you a good idea of what frequency to tune to. So do it, the end result wouldnt be far off if off at all from frequency on a high end meter. The only thing is, with a meter like the Epic 160, your frequency may shift in sensitivity from season to season because of atmospheric conditions. So make sure you do it on an average day around 65 degrees, and make sure its clear and barometric pressure is over 30 and steady.

That is all I wanted, just to get as close as possible so I'm not cheating myself. Now for a 65 degree day in Southern California.............. Quote Starting From Scratch!!
