What I am thinking of doing is making small sealed enclosures for the mid woofers of my component set. I figure that this will keep them away from any moisture that might get inside the door, and it would help with power handling and dampening of the rear sound waves. Has anyone here tried this before? I am particularly concerned with tightening up the midbass.

The very fist thing you want to do is get ahold of the thiele small peramiters for the speakers you are using. yes doing this can help. but do that first and then go from there. that will help you determine enclosure size

For the enclosure I am planning to make it as large as I can fit in my door. I don't think that I will be able to get the T/* parametes. Would it be worth it though? or would I lose too much lower mid bass? I would just try it and see but each time I take off the door panel the paper just falls apart, soon i twn't even stay on the door

What i ususally try to do when im building kick panels is build the enclosure too big, and then fill it in with expanding foam to make the box smaller and use acoustistuff or some kind of dense fiberglass stuffing to make the box bigger. why dont u try that

Yeah that actually exactly what I had in mind. I want to get the largest internal volume (real or virtual) that I can, that way the box won't raise the resonant freq too high. I am going to try to build a box by next weekend and listen to the speakers in sealed and infinite baffle configurations. Im hooking up my amp as well temporarily for the extra power for this comparison. I hate like hell to rip my door panels off though

you can try doing an aperiodic membrane design for your mids in the doors. it takes a little bit more tuning but the results are amazing. you get half the benefits of both sealed and infinite baffle design.

Ive always been curious about aperiodic vents. I know some of the basics, but exactly how do you build them and how do they work.

This is from scott cornells website. he had an award winning iasca sq setup and used the aperiodic design on his door woofers. shows how to build them but not really in depth on how to tune them. thats outta my league. i just know that they increase efficiency of the speaker by adding the little bit of resistance. http://www.rtol.net/scornell/doors.htm

Does anyone else have some info on this? It looks interesting...
