CleanSierra Posted October 21, 2015 Report Share Posted October 21, 2015 EBP usually is way high, making it not ideal for a 4th BP. The thing is, you can get away with Lot when you're dealing with that much cone area and power. You won't notice the mistakes of an enclosure design error since you have so much sub to kind of hide the faults. So what would happen if you put a sub with a high EBP in a 4th? Off the top of my head, a steeper F3 rolloffs. A lower EPB well yield lower F3 rolloff(taken directly from Loudspeaker Cookbook). Im not the one you want to try to troll. Just a fyi for you.

jroo Posted October 21, 2015 Report Share Posted October 21, 2015 this is years back, but I thought the 2500 series was the DD sub recommended for 4th order use? Some of the DD shops even had specs for 4th order use with them. Link to comment Share on other sites More sharing options...

The 2500 series are low EPB subs, they probably would work decently in a 4th order bandpass design.
