[QUOTE="mat3833, post: 8751230, member: 587645"] If you are that worried about weight you may be better off changing your goals. My single neo18 weighs something like 50 pounds. Most of that weight is the motor. I have a pair of 2inch coil ferrite motor 15's, and they weigh about 85 pounds for the pair. You are going to have to go with a neo motor to come even close to your weight goals. Personally, if I was that worried about weight I would get buck to design a 6th order for a single 15 or a pair of 12s and run less power. Sound pressure is all about displacement. A single 12 with 3 inches of Xmax can and will get louder than a single 15 with only 1.5 inches of Xmax. I would focus your search on a pair of 12s or 15s with alot of Xmax and a softer suspension. Running 5k to a single woofer is awesome and all, but I'd rather run 1k to a woofer and get the same output with a more efficient driver. Matt [/QUOTE]
