To choose the right subwoofer, you really have to understand how different subwoofer designs act in different situations and how they work with the rest of your system. We have always believed that the better you understand how to get the most out of your subwoofer investment, the happier you will be when you start to use your new subs. We find we need to teach most customers the fundamentals of subwoofer design and get rid of some misconceptions they may have before they really understand what they need. We don't claim to know everything, but years of experience in all situations has given us insight.The two biggest determining factors in choosing the best type of subwoofer you need are the subwoofer's specific application, and the type of enclosure you are going to use to reproduce the frequencies right above your subwoofer crossover point.
