Sub for mid bass?

RonRizz

What type of speakers are you running up front?? The first thing I would suggest is to enclose your Mid-drivers. You can use the foam baffles, or get creative and form them with dynamat or the like. you should also be sure to seal around the base of your driver before you mount it. You can use weatherstripping, or a small bead of silicone. You want to keep the air in front of the speaker completely seperated from the air behind. Even the slightest bit of leak can ruin a drivers performance. Just this one little thing will dramatically increase your mid-bass response.
Using a sub tuned to mid-bass frequencies..........eh. Just not what they are designed to do.
