Mounting the driver faced in.....

A bass driver with an open frame can get away with that (sub). Once you get higher in frequency the outside cone profile is needed.

It works great for subwoofers.




The only caveat is potential motor noise. Undersized venting and such can lead to excess noise.

I prefer it because it will increase the internal volume of the cabinet a bit because of the airspace in the cone, and really helps cool the motors in open air instead of heating up the inside of a cabinet.

And it looks sweet to have all that metal just hanging there.

Yup. People do it all the time....as Wi just posted above, even.

In my IB manifolds for my xxx 18's, I'm having one in and one out dual opposed. Saves alot of space with the magnet of the xxx. Have to reverse the polarity on one driver of course

The main benefit of doing it like that is to balance out driver non-linearity.

Thats what ive been told. Thanks for confirming.

I use speaker gasket tape from PE on the cabinet itself, between the rubber and wood, to seal a bit better between mounting points.

Closed cell foam that you can get from any hardware store. Comes in rolls. seals up the driver much tighter than the stock rubber ring.

Are you referring to my situation with one in and one out?

It does make the drivers more vulnerable to damage. You can remedy that by extending the top, bottom and sides, which also will lend a bit of additional loading while not requiring any calcs, like a bandpass does. Then you can add a grille as well if further protection is required, as in having kids in the house or anything else in the trunk.
