Message: <blockquote data-quote="Kippo" data-source="post: 589358" data-attributes="member: 10096">a sub put in a low tuned ported box will definetly sound better than sealed box with high Qtc.it is not hard to do tuning for ported box. Just use any simulation software for speaker and model the response that you like. Then find what is the port tuning and calculate the port dimension.say you like this sealed box sub response but you want it to play louder and lower. Plot that in eg. WinISD and then plot that sub in ported box response. Play around with the port tuning freq. until it either 'similar' with the sealed box response curve or make it go lower.to play loud i.e SPL, find your car resonance freq. and tune your ported box near (lower or more) your car resonance freq. Make your port area big (at least 50 Sq.inch for 15" sub as air in the port is like a piston. The bigger the betta) and make your box big (so that your sub becomes efficient hence betta with the limited power you have).nothing difficult here. No need formula here. Just let the software do that for you.</blockquote>
