[QUOTE="Moble Enclosurs, post: 7626037, member: 634917"] Hello! I have to mention a few thing here that might shed some guidance and I hope it helps. First, as far as the type of enclosure, without doing any previous modeling of the room and driver correlation with a specific response goal, you will not yet be able to determine if your indeed, specific, bandpass request will be optimal for this setup in regard to room modal gain and driver specifications. The first thing to do is figure how these subs will model in the room. And a little separation of them may be more beneficial for DJ type applications, such as putting each one in a high efficient design in separate locations. This will allow more control over the response curve in a larger space, because over a certain cubic ft area in relation to power output, a higher negative gain will occur in some spots in the room. These need to be compensated for in order for the output to correct the loss so you do not have to push it to the limits to get anything out of it effectively. the first step in determining this, would be to calculate the room function at specific points where people may be located, and use that plot to gain a negative response curve for the designs. As mentioned before, the best way to control the losses, or dips in the response that WILL occur, this has to be done by figuring the best location(s) of the subwoofers in the room. Corner placement obviously takes care of most of the horizontal plane modes (axial) that will effect you the most, but making sure it is done properly is key. Sometimes a few feet from the corners will provide the best response, and this would be determined by the gain response dips and when they occur in the frequency response of the design. So, in order for you to know what to do with an enclosure design, or two that may be more efficient to utilize for control, then this is a necessity. What are the room dimensions that you are working with, and where are the possible locations of the people and setup going to be? These are vital first steps to get the best idea of what design to use and where. Hope that helps you understand the first process in figuring for a design idea. [/QUOTE]
