When you say "milimeter gap" are you saying you could take something like a business card and slid it between the magnets? Because that doesn't sound good if that's how it is.
if i push it towards one side theres scratching but in the middle theres no sound. Im sending this one back anyways. They sent me the wrong sub, it was suppossed to be 2ohm. that one is 4.
i dont have an amp yet. should i keep this one and work with it or get the idmax12 d2
