After spending a few months reading around through most of the DIY build logs on here. I finally decided that I want to give DIY a shot...
Currently my system is..
Panasonic ST50 plasma
Arx A1 center
Arx A5 front right/lefts
Arx A2s as my rears
Cheapo blu ray player. (for now, planning on building a HTPC next spring)
APC H15 power cleaner
Omnimount RE18 rack
Rythmik FV12P subwoofer
and tons of other stuff
The room is about 11X13X triangle ceiling, (Not really sure how this affects the sound waves)
The Rythmik is a nice subwoofer, it sounds good. I don't think it is integrated well with my A5s, as the sound seems off like a delay. Since I have MCCAA or whatever it is (I don't like it) I don't have my subwoofer EQ with everything else. I like the sub I just want more... a lot more...
What I am thinking (For now) is...
2 TC sounds LMS-R 15s
2 sealed enclosed boxes
4 LMS-R 15s
LG Clone 10K 4 channel amp
4 separate sealed boxes.
I would be building the boxes myself, I think it would be really neat to give it a shot. I might spray paint them black or I will put some sort of vinyl over the boxes. I would like to go the sealed route, I know it takes gobs more power to get the same SPL as a ported. I honestly don't have enough confidence in myself to be able to build a ported box.
I don't know what would be the best size to make the boxes, I was planning on either Birch ( I think that's the better stuff?) or MDF 3/4''. I would also fill the boxes with pillow cotton stuff from Walmart, although I don't really know enough anything about the fill part of it so can someone maybe explain? Thanks
Also when it comes to actually building the boxes and braces etc, I am clueless. I am actually 17, go to high school, and work, and I pay for everything that is my room... Lucky for me my aunt does HVAC, my step dad is a pipe fitter/carpenter and my mom is a electrician/network admin. So between them all, I have I think every tool that I would need to build the boxes EXCEPT the tool that cuts perfect circles? I have a jig saw and a dremmel (Sp?) but I would like to be able to do this right the first time. What is that tool called? Also I know you have to put glue inside in the box to really seal the box up. I read about Titebond 2 and 3? I think 3 has a slower set time so you can adjust it? Not really sure... What glue/caulking do you guys recommend? I have a caulking gun already. What screws do you guys think are the best? I also have nail gun, I read over on another site about using a nail gun? Not really sure... I was planning on just using screws on the sides of the box, then adding some sort of putty type stuff. Sanding it all down, then painting the boxes. I guess I don't really know much about the boxes. If someone could design something using a CAD program or something. I could go off of it. If I have instructions I can build it. The boxes can't be wider then 18'' though. I thought about duel opposed but I just don't have the room.
My goals right now is to have the OmniMic ordered by mid-October range and to have the boxes built and finished by end of October. I actually start my new job tomorrow after school. Then have the subwoofers and amp ordered sometime in late November/early December.
What should I use to actually EQ the subwoofers? How do I wire them? I read about parallel etc, but I honestly just got confused. Since the subwoofers have two voice coils and both are 2ohms, is there a way to create a two ohm load per subwoofer? I don't know anything about this part, so any help would be greatly appreciated... The subs will sit on each end of the bed.
Here is some of the parts I was looking at on Parts Express

Just a few parts, for all I know most of those could be wrong...
Anyways I appreciate any and all help guys!! Thank you very much!!!

This is what my ceiling does.
This is where I want one of the subs to sit.
