TA_C10: Stage 1

[TA_C10]

And here is the result, the best I could get it. It dropped from -15 to -20 db almost. So the drone is still there, but quieter. I was expecting it to be completely cancelled. If you guys have any suggestions let me know.

I lengthened the pipe with my clamps, playing with several different configurations. I also shortened the pipe by turning the 2" capped end's 180 degree and putting them in the clamps backwards. But that shorted it probably down to like 25-28" and if you look at the spreadsheet, longer should have worked better than shorter. Nothing worked except the original 35" I originally built them to, which the Hz is still the same pretty much, but the db's went down.

I dunno.....
