[QUOTE="RangerDangerV2, post: 8130854, member: 637657"] My design is a burp design, the goal is 150 with less than 500 watts, which im getting close to. it just happens to be very musical. Model the Fc for a given woofer, if it needs a stupidly large rear chamber, then it is not optimal, second off, if you would take the time to read, a ratio is not chosen at "random." second, any program that gives you spl calculations is going to be wrong. unless it can factor in cabin gain, tempurature, barometric pressure, electrical inductance to the coils, and efficiency of the amplifier. this is why i dont use them. If you follow the guidelines that I have layed out for a 4th order, it will have a very transient response and get loud. If you are reading this in a voice that makes me look like a jerk, then read it again. Im not very good at typing politely, so if you need help, I can help you more via PM's [/QUOTE]
