[QUOTE="Marc Brule, post: 7774, member: 4682"] I've read some threads on cardioid and end fire configurations. I have only two subs to work with (Community VLF double 18's) that will be install under a church stage. My thinking was to place one at the very front edge and the other spaced back for 1/4 wave @63 Hz. Stage is 3 feet high and subs are 22" high (laying on sides) Questions are: 1) Which would be more suitable: delayed front in phase or delayed rear inverted phase (end fire vs cardioid)? 2) How much of the front of the stage should be breathable to achieve cancellation/summing? Any other advice is welcome. Thanks, [/QUOTE]
