Ok.. first off, this may confuse some of you.
I need to know if what I'm trying to do is possible, or even recommended. The best way to explain? MS Paint.. Here goes.
Here is my original enclosure, built for 2 IDQv3's. It is approximately 5.35 cu. ft. and it's port tuned to some higher frequency around 42 hz or so. It was built by a builder here in De. I wanted to focus on SQ, so he tuned it high. Well, I don't like it. First of all, I blew one woofer. Rookie mistake. Also, for me, sealed just does a better job of SQ, so I had him seal the port, and put a new top piece on for 1 15" instead of 2 12".
So, here we have the current enclosure. It has been sealed off, and now accommodates a single 15" woofer. I've decided to go with a single 10 in a custom enclosure for my SQ, but now I wan't this 15" to be LOUD and LOW.
I will have 2 separate systems incorporated in my vehicle. One single 10" for SQ, and 1 15" for SPL, controlled each by their own switches on the dash. So, I want to port this thing again, but I also want to decrease the internal volume.
My plan is to do this....
I want to put in place structural triangle braces, blocks of wood cut at a 45 degree angle. This should lower the box volume to my specifications. Also, I want to install a series of tube ports to create a new tuning frequency around 32hz.
Is this feasible? From what I've read, these structural braces are fine, but my main worry is the port within a port. Is this going to cause any issues? Can I consider the old port wall a structural brace? I'm wanting an SMD 15" or a AA Mayhem 15", and my reasoning is that this old port wall can serve as extra bracing..
Thank you for your help.
