[QUOTE="SubsonicSounds, post: 4602159, member: 594049"] Nissan, I have just done some quick research. I believe I am correct with my theory on internal volume affecting cone backpressure during excursion, and subsequently the overall frequency response curve of the subwoofer. (If we consider the JL Audio website scientifically sound.) While I will agree with you that there is "less" tuning involved with a sealed enclosure, there is still "some" tuning that can be done, and can be compounded by greater differences in air volume behind the cone. See: infinite baffle. Also, I would absolutely love to do a ported enclosure guys, but once again, I am really trying to reproduce these low frequencies. Im dealing with very long wavelengths, and to be honest, it would be difficult to create an enclosure that would house vents equaling the quarter lengths of these waves. To be honest, I would love to try a transmission line box, but I lack the woodworking skill/tooling to do so, and I really do not know where to go or who to approach on that one. And yes, I did mention above that what I trying to do with what I have is challenging/counterintuitive, but maybe what I learn from this can later to be applied to "bigger" and "badder" subwoofers. I guess you could say I am starting out on a small scale. That said - low frequency pwns. [/QUOTE]
