Would it be worth switching?

[QUOTE="Doxquzme, post: 8870014, member: 689267"] Every dyno test I've ever watched on the ACM 4.300 indicates it is very underrated. You will not hear any difference at all in my opinion. A doubling of power is needed to create a 3 db difference to the ear, 9-10 for a perceived doubling of the volume. 50 to 100 x 4 for 3db 100 to 200 x 4 for 6db 200 to 400 x 4 for 9db. The Sundown SFB-1000.4D will get you close to double volume (not like you can or will actually be able to do this, but...)
