Tim, I'm not trying to look down my nose, like you said, you know that.... Trying to be helpful, in the open so maybe everyone here can benefit. Not saying that I know it all, and I'm not saying that your way doesn't work. It works but has its limitations.
Bitching about someone sharing knowledge is pretty counterproductive. Tim knows damn well I'm not here to belittle him. I do like the way the sub box turned out, and its obvious that Tim is capable of doing stuff right. I'm trying to do a little more than just say "good job"... Lets take it to the next level :)
Haven't had a lot of time to come post lately, but here are some of the reasons I am making suggestions.
If the rear wave is allowed to interfere with the front, it can effect tonality. The rear wave can commingle with the front, causing cancellation, which is lowering the output of the affected frequencies. This can lower midbass output, and could even change the sound of a voice or instrument in the music reproducted. This is why I recommend sealed as best as possible the rear wave and front wave by closing up any and all holes. Putting a true sound barrier over the entire inner door skin also can help this (and block road noise)
I used the same mids you have in there (i sold them to you, duh)... There are a couple reasons I recommend baffles. First, its a stamped basket, if the sheet metal isn't perfect, or you aren't very careful screwing them down you could warp them. Second, it helps stop the transfer of energy into the sheet metal of the door. You can get those speakers to image a pretty well, with some tweaking I could get drums to be coming right out of the center of my dash. But the minute something in the door buzzes or rattles, the image goes to shit and the sound is coming out of both doors again. There are other reasons to use a baffle as well, that are in regard to the response of the speaker, don't really have time to get into that right now tho.
How much power are you giving those mids? Using the passive crossovers?
