[QUOTE="Moble Enclosurs, post: 7448303, member: 634917"] It would depend on the phase of the output. If the phase is calculated to be say, 90 degrees off-axis, the facing them up would be more beneficial. But if you do not know the phase of the box, say it was pre-built or something, then your best bet is to always face them the same direction as the drivers. The less distance between the driver output and the port output, the less changes to the phase of the response, and the actual response in the end. The only reason to face them in any other direction is, 1. If you do not have a choice 2. To correct the phase difference in the output. The flatter the phase to 0, the smoother and broader the response. But, considering a vehicle with LF response and a lot of power, the resonances in the vehicle will not care too much about phase below 150Hz anyway. So, if all of this is too much, keep it simple and face them the same direction as the drivers if you can. [/QUOTE]
