Is this a one-off gig like (1) show or is this going to be a permanent gig PA?

If this is a one off I would build lots of Decware approved bass traps and stack them (2) high in each corner if possible if this is in a club or lounge. Soaking up bass nodes and getting rid of pockets and nulls will give your bass response such a killer sound and even pressure the entire crowd will be blown away from the sheer impact, audibility and musicality of the mid/low-end bass. Keep in mind that many people have never heard this before so hearing it will blow there mind and most likely bring them to tears in tension relief from a pair of Imperials or Imperial SO's.

This alone might reward you with such initial first impressions that you might be remembered. If that happens and you get chosen for further audition then build on your trademark(killer sound) and put lots into getting them more of what they heard the first time. I would talk to Steve Deckert about building a all tube triode amp, I absolutely loved the sound Steve got in the mid/bass of his SE34-I model amp in true triode. That particular voicing of the EL34 pentode coupled with SS rectification had excellent snap and harmonic attack. I would love to hear what Deckert could do with a KT88.

Take care,

Ok, thanks for the advice...But how do you think it will sound?It will be used basically one time for a big crowd, and numerous times for smaller crowds...Do you think it will be big enough and loud enough for about 750 people...and will it shake the ground?lol

thanks

The gym we are playing in is just a one basketball court sized gym.  Our sound guy wont let us use anything but imperials.  He keeps on going on about "shaking the ground."  

I had amazing improvements in bass when I turned my Imperial around so it fired into the corner.  Better results with the Imperial SO than with the standard Imperial, but still a marked improvement with the standard Imperial (used as a sub).  Hopefully you will have time to try this kind of thing during setup.  If you can't get a corner I would suspect you might see a slight gain if you just turn the Imperial around so its a foot or 2 away from a wall.  It also seems to add more than just a 3-6 db increase in volume...its that increase in volume with no additional power that gives you something special, like the system doesn't have to work so hard to make the bass...effortless bass.  Note that I saw no improvement when the Imperial was placed in the corner facing out, only when turned around and playing into the corner.
