Hey everyone new to audio and new to the forum. I have a few questions about a sub box that I am planning on making. I have just purchased my first sub and built a sealed box around 1.15 cu ft. I am very pleased with the sound but am interested in hearing it in a ported box. Here is where i have questions. The t/s parameters are different in the booklet that came with the sub and what the manufacture has online. I'm guessing I should go with the booklet specs. The booklet also lists specs for building a ported box but I have read quite a few posts saying that a custom box is better. If so, how? Because sound is so subjective it seems the only way to find the best box would be to make as many as possible and pick the one you like the sound of.
