We’ve talked before about deciding to buy or build your own subwoofer enclosure. If you’ve decided to build it, then using enclosure design software will make it easier. It will help you design the perfect box to meet the specs of your subwoofer.
Some programs are free while others can run into the hundreds. It really depends on your skill level, experience and budget. We found a free version called WinISD from the Linear Team along with an online version. Amazon had a few selections, with True Audio’s software at 50% off. And then there’s a high end design software offered by PrismSound.
Since each subwoofer is different you will need to design a plan specifically for your model subwoofer. If you’re unsure of what type of enclosure or what size to build for your subwoofer contact the manufacturer. They know the subwoofer better than anyone and they should be able to help you with your specific situation.
