I'm moving my midbasses from the door to sealed enclosures under the front seats and my question is: how much stuffing should I put in the enclosure? I have half a bale of rock wool on hand so that is what I will be using. I have searched this question online and there are many opinions but I was hoping someone here might give some learned advice. BTW, the MB are 7 inch Scanspeak Discovery...if that makes any difference.
