a very poorly sealed one at that.

fog machine and painters tape with an spl meter can go a long way!

I just use smoke bombs and white silicone.

That makes perfect sence but both had 18sq per cube.

well tune it lower, you will lose very minimal on the high end as you have enough port area to let the sub go ape ****. it might not hurt to even bring it down some to about 17-16.5 per

how do I get rid of the planes on the port opening and sub cutouts so I can see inside the box without the plane being there??

It's better to choke a sub on airspace than it is to choke the port. Choking the port will create a very uneven frequency response as you add power as the port will be unable to move any more air at or near tuning. No point in tuning low if you dont' have enough port area to actually move air at those frequencies. Low airspace does reduce tuning peaks some, but if your subs have alot of powerhandling, you can somewhat overcome this inherent effeciency disadvantage.. I'd say Anton is right on this one, generally speaking.

db drag, but the local shows do it meca style. and why should I go with a single shared chamber??

I thought the rule of thumb was shared chamber is a 3db gain from separate chambers. (Obviously a generalized statement)

Idk if that is true but im just going to wait until I build my 15s to design the enclosure.
