Edges of glassed pieces.

I think it's a great idea..the more bass up front..the better the sound stage.

But for those 8''s to perform you should use some kind of enclosure..even free air type or infinite baffle is not going to ever give you the quality of a sealed or vented enclosure for really nice deep, yet tight bass. And use some kind of sound deadner to help with resonance and rattling etc.

Thats a pretty cool little pod.  Weird insert though.

The way I look at speaker pods are like this.  You know those 6x9 prefab boxes places like Best Buy and circuit city sell?  Anyone who has used them knows that you lose any reasonable low end that the speaker has to offer cuz it just doesn't have enough airspace to create the spring that pushes and pulls the woofer far enough to do so.  Therefore if I want low end out of a speaker pod, I don't seal it, I don't port it (necessarily) either.  However, if you were planning to cross them over in such a way that you'd filter the low anyway, then screw it, seal em up!

6x9 holesaw! thats priceless.  We always have our new guys call around to some other shops to try to locate a 6x9 hole saw and a wire stretcher.  One new guy actually had  another new guy at another shop start calling around looking for one too.

If you want to get a 6.5 pumping in a small pod...give it some power. But agreed, the more airspace the lower the response..too a point...a real quality 6.5 used for staging is not quite like a 6x9 free air on a rear deck.

regardless, the 6x9 holesaw has been put on hold. too dangerous....lol,  just use an airsaw for petes sake. Hey another one is call around to autoparts store saying you need a johnson rod for a 86 buick..haha
