Hey I just read this whole post!

Some people were talking about aiming the sound pressure at the mic to increase the spl measurement. Since high frequency is more directional, why not use a big monster tweeter? I know nothing about these spl contests and their rules, but if I were going to try something I would build a narrow horn facing the mic. Get multiple titanium diaphram PA style tweeter motors (type used in outdoor concerts) and just blast away.

In dB drag you must play under 80 Hz, so high frequencys wouldn't work, you'd have to go outlaw if you want to try that.

im building something similar to the edge audio truck in an explorer. i say similar but no im not copying in any way. its actually quite different, but on paper it seems similar. its only using a partially enclosed half wall, like a sonotube/bandpass half wall. ill let you know how that works.

Theres alot of good threads around here that involve critical observation and mathmatics. It's just a matter of moving past the typical walmart boombox mentality.
