Inverted subs in a ported box

[x2o 10+ year member]

He's talking about the idea of inverting your subs in order to save room on internal volume, thereby making your box smaller. That is true, but then you have speaker frames and motors sticking out of the box, making the whole assembly that much larger. Airspace is not utilized as efficiently as when the subs are mounted inside the box, and their volume accounted for in the over all dimensions.
You think he is saying space will be wasted in the box, but he's actually saying space will be wasted inside the car (but outside the box).

Ah! Okay! Thanks for clarifying that. I was quite confused, haha.

And yes, that makes sense. The only way I can see this as ideal is if he owns an SUV and plans of firing the subs up, since if he mounted them traditionally he still wouldn't be able to utilize any of the space on top since the subs would be there. If planning on firing forward or back though in an SUV, car, or whatever, inverting them would be a tremendously inefficient way of 'saving space' as pointed out.

I was talking about spending the time/testing to find the optimum amount of port area to maximize SPL. Many times this involves building mutliple boxes of different sizes, proportions and layouts just to find out which gives the best results. But that's for the serious competitors. If you have to ask about it, you really dont need to do it.
There is such a thing as too much port area too, the sub unloads too easily. Im not necessarily saying two 6's would do that in this case, Im just saying port area benefits have their limits as well. For most daily systems, it comes down to not choking the sub off, and not displaying audible port noise.

I'd listen to this guy //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif You could also do cut outs for 2 more aero's for your SPL set up and just block them off for daily...

Ya, your not gonna get much more than what the subs would displace originally. I cant imagine the cone depression giving you much at all either. So like if one sub was .2 ft^3, most you'd get freed up would be a little more than~.4ft^3...doesn't seem like its worth it, unless its for purely aesthetic reasoning.
