 Hello all, I am looking after acoustic pingers to locate my sub, with the lowest frequency possible to get the longest range. However, I fear low frequency might be audible inside the sub (or giving head aches) especially given the power emitted.A youtube hearing test shows me I cant hear frequencies beyond 14kHz... so I am aiming for 16kHz
Have any of you had experience with these low frequencies <16kHz in a sub? 

regardsAntoine
