I've been doing some reading trying to figure out what type of sub I should get. I'm trying to narrow down search to what types would suite my needs best. I'm pretty sure I would like a sealed sub best but would a servo have it's place with the music I listen to? I listen to NIN, Tool, Crystal Medhod, some rap but mostly rock. NIN and Crystal Method use alot of synthesized bass they are the most demanding bass cds in my collection. I know the basics of how a servo works and how they are very accurate but for the music I listen to would a servo have it's place? If I don't go servo I have my eye on Adire's tumult in a sealed box.
