BigPimpin91 Posted October 23, 2011 Report Share Posted October 23, 2011 Also, did you mean 1.5 sealed so .75 each? 0.75 to 3 would be a 4:1. LoL .75 on each sealed side lol Oh, so you're running individual sealed chambers? Got ya. BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...
Notoriousj76 Posted October 23, 2011 Report Share Posted October 23, 2011 How do you design a 4th order? I've been wanting to try one for a while but everyone tells me they are burp boxes. I just want one thats really low, peaking around 35 if that's plausable. Any tips on the sealed to ported ratio and how tuning affects things would be nice to know. Thanks Link to comment Share on other sites More sharing options...
