DavidClark Posted December 1, 2015 Report Share Posted December 1, 2015 How big should I make the sealed side in a fourth order bandpass for a 15" lvl 5 m3?

corona_jeff Posted December 11, 2015 Report Share Posted December 11, 2015 depends on power, these subs technically arent designed for 4th orders Actaully the M3 models the best out of all the other lvl 5s for a 4th. But sealed sizes will vary based on what you are trying to achieve and desired sealed resonant. However I will share what I have ran and tested. sealed per of 2.05cu will yield a seal resonant of 46hz. Which should give you a start point 2 Quote Link to comment Share on other sites More sharing options...

CleanSierra Posted December 12, 2015 Report Share Posted December 12, 2015 Damn that's a lot of power per sub Quote Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
DavidClark Posted December 12, 2015 Author Report Share Posted December 12, 2015 I had two 10k's, I was rising to 6.6 ohms ( like 4900 watts total @ 33hz) and losing a ton of power. I am in the process of redoing the enclosure ( making sealed side bigger and opening up the port ) but my point is, I probably wont be seeing anywhere near 5k per sub.

CleanSierra Posted December 12, 2015 Report Share Posted December 12, 2015 depends on power, these subs technically arent designed for 4th ordersWhat does make a sub designed for a fourth Typically an efficiency bandwidth product that is within an acceptable range. Fs divided by Qes should be between a range of 40-100. High Qts can also be another good sign that the sub is suited for a sealed or 4th order bandpass enclosure.
