2 possible solutions - get a bass trap tuned to that specific frequency from GIK, or kick the Hypex amps to the curb and get the ones with EQ. Or both! Haha.
Kick $600 worth of brand new amps to the curb!? Yeah right
No, really, if I worked at it enough, and had any clue what I was doing, I might be able to fix it with room treatment. Also, I know there is tech out there that might work such as the DSPeaker Anitmode 2.0 Dual Core but @ $1,100 it costs almost as much as three A370PEQ amps.
Though at this point it is moot. The demo is over, I have broken the Wedgie system down, got my wife's N3TL HT system back up and running and except for wrestling the two bass units up the stairs, have everything back in its original itsy-bitsy-tiny-weenie room (no yellow polka-dot bikini here)
I am going to need to figure this out at some point, especially if I continue to do demos and take them to shows.
