    Re: Port calculation???

    i'll give you the bassbox pro calculation. its usually off by 1-2 Hz., but hardly audible. i'm much too lazy right now to do it properly.

    Re: Port calculation???

    with the dimensions above, i got a port length of 26.14, width of 1.75, and height of 14.5 for a tuning of 30 Hz. This brings the volume down to 2.79 ft. ^3. this was all done on bassbox pro, so it may be off by 1 or 2 Hz. (Its usually higher than it really is, so its probably somewhere around 32 Hz in reality). hope this helps.
