[QUOTE="SlugButter, post: 8735242, member: 678073"] in a free air environment you would get a sharp drop off at 38hz in a ported box at 38 hz, but with cabin gain in a vehicle, you likely will have a hump in the low end frequencies anyway. I had an Orion sub back in the day that I had ported at 40 hz, but it played lower than that. For some people, a flat signal AFTER cabin gain is what is considered “SQ”, which is easier with a sealed setup. Ported setups have a nice little hump in the low end that some people actually prefer. I’m a fan of ported setups myself, but I like to find subs to run small and tune low to get a little flatter response after the cabin does its work on the lower frequencies. [/QUOTE]
