[QUOTE="JimGore, post: 60751, member: 3"] In my mind that is an isobaric setup, but I see the "clamshell" in it ;D There is no reason to do that for an IB. We use isobaric when we try to get the internal volume of the enclosure smaller: If a 12" drivers requires a 100l enclosure volume, then we can mount 2 of them isobaricly so that the enclosure now only needs to be 50l in volume. You do however loose some efficiency (3dB) because you only hear the output from one driver, but are powering two. In IB, the enclosure is usually thousands of liters in volume, so we don't need any interesting tricks there. Regards, Ian. [/QUOTE]
