I'm looking at 3 mtx subs, MTX Thunder4500, MTX XThunder XT12-04, and MTX XThunder XT12-44. They are all close in power, etc the only thing that are dif are the Cone Material, and Surround Material. Whats the difference between Polyether foam and rubber for surround, which is better? and how about Carbon-filled Poly vs. Polypropylene for cone material? Thanks, I'm very unfamiliar with these materials
i really have no set budget, those mtx were 100 bucks for 2, but under 150 for 2 12". The thing is i have a weak amp and i don't want to upgrade quite yet, (insignia 360 watts bridged @4ohms)
