Hey all,
Not my first box build but wanted to see what others think. The only thing I got left to do is carpet and caulk. Anyway heres the specs:
4.5 cu. Ft. per sub with a slot port 3.5" X 16" X 16" (also per sub)
Supplies:

Flushmount baffle:

Double baffle together:

Divider with port bracing and ports attached. There may be a better way of doing this but this seemed easiest for me:

Add front face and a health serving of wood glue:

With top plate (Madden added for scale):

Like i said, the only thing left to do is capet, gonna do the trim the sides with wrap around carpet approach, hence the small nails. What do you guys think? Gonna power them with a XX-Colossus II in a Expedition.

1 question kinda confuses me why you would flush mount and then invert... u still have the big motor structure sticking up??

but great work none the less

**** - not sure that port bracing was necessary but wont hurt anything other than take up some air space.

you should have considered the port when you did the flush mount. Good job though.

Get rid of the 20 farad cap mentioned in Sig ASAP........

DarkFox

Wow, lots of stuff to answer.

Maniac, The Inverting was to make sure it fit without setting it all the way in as it is a very tight fit and would be hard to get out, it wont be inverterted when I am finished

James, I did consider the baffles into the port length, the cutout on the inside is 14.5" + 1.5 " I gain from baffle and base plate, giving 16" total port length.

Gema, it is tuned to about 33.3 Hz

Pop, Why get rid of the cap? Just out of cureosity(sp?)?

you realy dont need to get rid of the cap. some people here dont like them since they realy dont help much or at all in a well design electrical system. but it dont hurt having them in any system in any way.

the enclosure looks greate. it'll most likely sound very good as well. video will be awsome ones you get them powered.

i do suggest brasing them long walls from the front of the enclosure to the back wall . but you can leave that for affter you have tested the system, "if" you feel some flexing from the panels.

ones again great looking enclosure. nice selection of subs too.

Just wanted to let you all know, its the first time I have used that type of caulk I showed in the pictures. It works very well, I put it on yesterday and it dried very rubbery and has a good seal. I think it will be what I use from now on

Wide carpet FTW!

Used 10 yards of 80 inch wide carpet to get everything in my system covered.

What have you powered with that XX Colossus...how do you like it..did you have to upgrade your ALT.?? ive heard that thing drains power like fat albert eats a gallon of ice cream. Are those last years models?

DarkFox
05-13-2006, 07:49 PM
Havent powered anything with it yet, and we are upgrading to a 200 amp alt.. Also, its the newest moddel of the Colossus that we are using, however there are new XX amps out for this year, we just went with the Colossus for the 2kw @ 4ohm mono. If the charging system holds up this should be the kinda system you can run all day long without overheating etc.

are those other 3 amps in the pic this year though...like the 4406..cause I have the new one and it looks a little diff.

DarkFox
05-13-2006, 09:24 PM
Oh. nahh those other pics were from another system I did late last year. Those are all last years amps. They did a real good job though. I HATED that Clarion head unit though... 2v pre-outs and no sub specific outout Front / rear / non-fading
