[QUOTE="mat3833, post: 8791270, member: 587645"] See, my definition of crazy doesn't really match up with most other definitions. I want lots of cone area, lots of displacement, and high efficiency. I can totally respect the guy running 10 - 15" subs that weigh 55 pounds each on 40k watts. That's just not what I want to do. I want the most output I can get with the least input power and the least weight. I'm trying to put my jetta on a diet, it weighs 3800 pounds from the factory, last thing I want to do is add another 1000 pounds in audio. At that point I have no choice but to do an AWD swap and build the block to put down 450whp to keep the same level of "pedal fun" I have. My dream subs would be some crazy neo-slug deal with a motor force in the 520 range, a super stiff and lightweight cone, a 3 or 4 inch copper coil, all the cooling, a low inductance, and a usable 70% BL x-max over 80mm one way. Hell, might as well throw in the good-ol JBL "Differential Drive" technology so you can't hurt the driver from a mechanical perspective. Oh, and it needs to be efficient so that it can use that Xmax on like 2k. I absolutely love infinite baffle setups. Lots of output with low power input. Get a sub with a guerilla grip on coil movement(from an electrical perspective) and a low moving mass, and you end up with crazy accurate bass with some serious force behind it. Because of the laws of physics, what I dream of doesn't really exist. At some point you have to add power. You can't have 6 inches of peak to peak excursion on 2k. For now, I think the 18's I have are the closest I can get. If you are up for having some fun I can send you a beehive and you can build a top for it and play around, lol. Matt [/QUOTE]
