Re: Help Designing Box.. Building My First Ported
That design looks pretty good if you can fit it in your vehicle. Subs are allowed to share a chamber, which is the case here. 28htz is a little low unless you want a strictly sound quality setup. Simply put, tuning is what gives the sub its loudest range of play. The tuning frequency isn't always the loudest frequency that your subs will produce. It is complex. The tuning is more related to the frequency range you want your sub to produce. Higher tuned setups (38-40htz) tend to get louder but can lack on the lower end of the spectrum. I hope this answers some of your questions.
