Prefit and pre-assemble (using no glue) all parts to make certain that everything fits tightly and accurately before final assembly. Adjust any pieces to correct for any minor cutting errors. Sub-Woofer Sealed Boxes need to be airtight. Seal any gaps after assembly using Silicon caulking/sealant. Openings for Ports should be offset at least 2 inches away from any inside edge. If using 2 or more ports, place them as far away from each other as possible, towards the end of the cabinet (away from the speaker) on one of the sides. -------------------------------------------------------------------------------- Results Generated: Mon Oct 18 22:51:21 2004 This program makes a limited attempt to generate the estimated frequency response of this cabinet design. See the Links on this Web site for online calculators to assist you in this area. This calculator can create cabinet designs that are impossible to port properly - its free software and you'll have to judge for yourself if what it generates is useful or not. Play with the parameters and judge the effects - You'll quickly see why there is no standard Subwoofer design |
