    @123toid yeah the port was really the greatest compromise I made. I’ve found that having a port that has greater than a 3:1 aspect ratio will begin to lose port output because of resistance caused by the property of <a href=" removed link ” target=”true”>Poiseuille Flow. Sharp 90 degree turns also add resistance. So all around bad in my case lol. 

    In your case, passive radiators definitely seem like a good idea, but good enough ones would be expensive and that defeats the purpose of the budget $200 15” sub. 

    Some sort of down-firing port could help eliminate the sound of chuffing allowing you to have a smaller port area. Not sure you’d be able to get it small enough to make a difference though. Good luck with the design!
