    The practical issue for rear-ported speaker is that it's not a good idea if the speaker is to be placed against a wall or with little clearance w/r/t the wall. Out in the open, either porting options are fine, though aesthetics may play a part in choose a rear-ported speaker over a front-ported speaker.

    I seem to remember several threads from some time back discussing acoustic coupling. The consensus seemed to be that drivers arranged close together have greater output than if summed seperately; does this hold true for a port too? IOW, does a port acoustically couple with the driver?

    I'm also curious as to how a venturi in the port would affect it.....

    sorry for wandering

    hi patrick, and thanks for your help. i would rather front mount the port if my baffle will allow. if i remember right, my baffle will be about 23" square does it seem like that should be large enough for driver 15 7/8" dia. and 4" dual flared port without crowding anything to close together? this is my first sub project and want to be careful, not to screw anything up he he. reguards, steve all [​IMG]

    Ah, this is about a subwoofer, well, then you should not rear-port the sub if you will be placing it in a corner or against the wall. The porting options for a subwoofer are in the front baffle, or slap on some legs and port downward (usually along with the downfiring driver on the bottom baffle). Hell, you could port it from the top as long as you don't cover up the port opening.
