Many will trim the bottom and sides out of the back of the baffles to shield the driver from water that may get into the door.

If you really want to improve midbass from your door speakers, the best thing to do is add sound deadening to the inside of the door. It costs a bit of money but there are good deals on deadening material out there. It's easy to install and makes a definite improvement in sound.

if you read the sound deadening showdown wood baffles with clay then the speaker mounted "decouple" the door from the speaker and it reduces rattles and sounds better.

there are also these things that i have seen called speaker cups they are plastic like a box fro you speaker it looks like a cup that you put in the door and then put the speaker inside of it hmm you know like a cerial bowl it projects sound better not so much is lost in the door behind the speaker

so it just reflects the back-waves right back into the speaker cone?

I've seen those speaker cups before, i think they're made by metra

they'd be a great idea if they were bigger, but they're so small that rather than adding suspension to the speaker, they'd keep the speaker from moving almost completely

make yourself a 1/2" or 3/4" MDF baffle for each speaker, and just go to town with damping material on the door panel itself. The biggest thing detracting form midbass is backwaves coming back through the door into the cabin, you can go back in and deaden the outside of the door for noise insulation later.

The sound isn't "lost" in the door panel. The rearwave does not (or atleast, shouldn't) contribute to the sound you hear. That is strictly the frontwave of the speaker. The rearwave in a sealed enclosure is reflected back towards the speaker. For subs, this isn't a big deal. For speakers, this can create distortion and decrease the performance of the speaker. Which is why most worthy home audio speakers have thick foam lining within the enclosure...to prevent the reflection of the rearwave.

Deflex pads/foam padding are still desireable in an infinite baffle alignment. However, the problem is amplified when using an actual enclosure with midrange speakers.

Not to mention, most car audio speakers are specificially designed to perform best in an infinite baffle alignment. Sealing the speaker will only hinder the performance in most cases.

this is why most people end up not liking those foam baffles (not enough bass), and end up cutting holes in them.
