Cant find low end in Theatre, with 18"

[Ric5]

You have an 18 in your Rig and I assume 2 18s in the pa. That is lows coming from 3 sources. Maybe there is comb filtering going on. Try moving your amp location. Maybe on the side of the the satge or try sidewashing the stage with your rig at the edge of the stage.

Or maybe play with the eq.

Or maybe run a small rig with a line out to a powered sub.

Check how that S-1 switch is set... Or just get rid of it. That might be your problem.

Glad to hear you got it sorted.

i would try a 15 in place of the 18 you stand very close to your amp someone mentioned your to close to the 18 i agree.

This is the nature of Bass unfortunately, you need hard surfaces for the sound to reflect off of or it will just keep travelling and you wont hear anything. Unless you go way louder than you currently are.

That said their is no need to replace your rig. Unless you dont have PA support and monitors. then you'll need to run a bigger rig.

Peronally I dont like playing with a high stage volume, its not very efficient. This is music though so efficiency is irrelevant to most people

Everyone has their own opinions on this, and some preffer to lug around full stacks everywhere.
