Youngone your'e giving me too much credit there. I just thought it would look good. I am sure it will have some effect on the sound but I doubt it will be noticeable.

Hey man it might be kinda sweet lookin if you just cleared it like that. It would give it a camo look. Just a suggestion. That is one bad *** box. It might be kinda cool to airbrush some ghost flames on the cones youve fabbed. Thats one sick box.

I'm giving you the credit for a reason not gust cause want to. that was a brilliant way to design a box. that extra dip that you have formed around the subs cone will reinforce the sturdiness around the area that is going to be flexing the most. another thing is that if you do it that way you can put some kind of fabric over that dip that goes down to the sub. and make it look like there isn't even a sub there and the only way to now is when it is playing and the fabric will move in and out in unison with the beat. if you do do this you can get some really cool fabric out there in cool colors to. make sure it lets air through it but still covers the area well, so you cant see the subs. but if you are looking to do something else go right ahead that design gave me that idea so i though i would share it. that design is brilliant!!!!!!!!!!!

Box looks alright.The upper rings should have been hit with a roundover bit ,inside and out.Would have given it a lot better look.I think you are going to have some cancellation issues with youre subs firing in totally different directions.And you better add about 10 more layers of matt to that thing,or you will watch it dance.
its huge ,but all in all it looks good.Keep the pix comin.Im doing somthing simalr in a 88 Z24 with 6,15s

Shudnt the subs firing in different directions reduce cancellation as opposed to subs firing when they face eachother

Jlord I would tend to agree with you that because the subs are all pointed in completely different directions that cancellation will not be a concern and even if there is any I doubt it would be of a significant level to be noticeable.

They are not facing eachother <180 degrees>, therefore there is no chance of cancellation.  On top of that, the wavelength of sub-bass frequencies is very long (usally over 15-25 ft).  This means that the two speakers facing eachother must be about half the distance apart compared to the wavelength at the Fs of the speakers to cancel out, if I'm thinking through this properly.  Therefore the speakers would have to be sepparated by 7-15ft at least.

Someone correct me if I am wrong.

It's all about nodes and ant-nodes in the audio signal...

Unfortunately I have been swamped at work so I haven't had much time to work on it, but I am going to finish it eventually. I did do a little more sanding last weekend and it is almost ready for paint.
