[QUOTE="Ivan Beaver, post: 72200, member: 30"] Re: Carrie Underwood Sub Woofer Array Yes any speaker can be used in an endfire or cardioid array. HOWEVER I am starting to "rethink" some of that statement. If you have a physically directional sub- the energy that is used for the "rear cancellation" is going to be less by nature. So less cancellation. HOWEVER-because the energy going to the rear is less-that means less sound-in and of itself. I need to find some time to do some testing with larger subs that have physical directionality in a "steered" array to get a better handle on this. It may end up being a "wash", or some new and unaccounted for may arrise. Measurements will tell. For the second question-directional arrays work best when they are free field and away from all boundaries. As soon as you start to introduce boundaries (strage deck-walls etc) things start to change. How much-depends on the particular situation-what the wall is make of etc. So you will still get some directionality-but how much has a lot of "depends" attached to it. [/QUOTE]
