Pierce Barrett Posted October 30, 2013 Report Share Posted October 30, 2013 Can somebody clarify this for me, I was planning on doing a 4th order wall with four DD 3515's but I have 'heard' that the suspension in the DD's don't like 4th's at all. How true or untrue is this? 2006 Ford F150 4.6 3v (2) Digital Deisgns 3515's D4 Digital Designs M3B w/ Toolmaker Dual Inputs Mike Singer Built 340 Amp Alternator Arc Audio KS 300.4 *mids and highs to come soon* Alpine 148BT And tons of 0 AWG Link to comment Share on other sites More sharing options...

CleanSierra Posted October 30, 2013 Report Share Posted October 30, 2013 That sub will work just fine in a 4th order bandpass. EBP is 63. Between 50-90 will work in both vented or sealed enclosures. Below 50 sealed or bandpass only, above vented only. 50-90 can do either enclosure style. EBP is determined by Fs divided by Qes. Im not the one you want to try to troll. Just a fyi for you.
