[KJDJ]

The biggest problem people have with subs is they use 2 when 1 will do. 2 subs spaced 20' is a problem.
Wavelength calculations are a pain. If you figure for say 40Hz it won't do any thing for say 50Hz.


I have 2- 18" Killo-Max's in a pair of JBL boxes powered by a bridged PLX3402.
I do mostly 100-200 guest events. 90% of the time I use 1 sub.

Most folks run 2 subs and stand between them right in a standing wave.

If you must use 2 in a room put your full range on stands and set the subs side by side in front of you or on the floor if your on a stage. I have even put them to one side.

If you have the bass coming from 1 location the low end level will be much more even througout the room.

If your getting blasted, other areas of the room are also getting blasted. In our buisness it's always seems to be the grandparents table.
