Incriminator Audio's website gives a range of enclosure sizes, tuning frequencies, and port areas for this sub. I would appreciate some help with designing a ported enclosure. I used the Resonant Engineering sub enclosure calculator for a rough draft, but I am not sure what I should use for the overall size of the enclosure, minimum port area for this sub, and tuning frequency for a daily driver (no competitions).
I listen to all types of music and love deep bass rap. I don't really listen to test tones. I have heard that Resonant Engineering's enclosure calculator is off by a bit, so I am skeptical about using it, but need to physically see something so that I know exactly how/where to make my wood cuts and how to assemble it. I think it would be perfect if someone could help me decide on what specs would work best for sound quality and then once that is figured out, what dimensions to plug in to the RE calculator that equate to the correct cuts to make for the wood.
I don't know how the 7.5 cubes vs. 10 cubes effects the sound, what minimum port size is needed, and what tuning frequency to use to make this setup sound as good as possible, while maintaining good spl output. Keep in mind that I have a dvd player in my truck, so I will be watching movies as well (deep bass). I appreciate any help you can give me. The website doesn't list the T/S specs of the sub.
