Box design.. what do ya think?
This is for an xtracab tacoma
Box would be carpeted, no neons, no fans, just a simple box that would be hard to steal.
upside, it fits nicely
downside, those CDT MS-80's are at the boxes max mounting depth.
i could switch to a shallow 10 later on, but not the Edesign 8 that I wanted to.

Re: Box design.. what do ya think? (mrkln)
Buidling it myself. Those are my "blueprints"
the mounting depth in the box is like.. 4.5"
Something like .42 interior size. I can make it slightly taller and lean the woofer back for maybe .25" more, but that's it.
i may just design a down firing set up, with a taller box, and the amps where the subs are, I dont know..
It'd be fun to do somethign fancy,. but then id need a matching amp, and im worried about things getting stolen.

Don't forget you need to provide space for the voice coil vent at the back of the speaker.

Re: Box design.. what do ya think? (Nevermind)
Make sure you provide some way for the amps to vent their heat. In an enclosed box like that they may overheat and clip or worse. A small fan or just some venting out the rear should do it. Just make sure that part isn't airtight. Also, I would make the lid end at the boxes. Make the boxes higher than the rear by the hight of the lid so the final effect is still a flush top. This puts less weight and torque on the lid and lid hinge and also gives you more volume in the sub boxes for the same space used. :grouphug:

Re: Box design.. what do ya think? (92TripleBlack)
these ARC amps dont even get warm after an hour of the sound cranked... I'm not too worried about them overheating :thumbs:
the reason the lid is like it is, is so the carpet looks seamless... but well see how well that actually works out. 3/4" mdf certainly wont work, and particle board would warp at that size... hmn.

If you can figure out a design that you are happy with, you will get better output from the subs if they are firing down into the floor. That should help out those cdt's some. :yesnod:

Re: Box design.. what do ya think? (mrkln)
I've alwyas wondered what teh best floor is to fire the subs at?
MDF? Rubber? Steel?
wont do me any good if the floor absorbs the suond.
if i make it pretty enough, maybe I'll enter a SQ competition...
you think a window into the sub swould be cool? They arent pretty though...

If you install a window in the box, you will have to contend with the material.
I would built it out of 5/8" MDF. The reason I would do this, other materials are scary for acoustic response.
and 3/4" is not required for smaller 8" subs... unless you wanna do 10" later.
facing the sub down is cool. even into the carpet.
if you see the home boxes, they fire the subs down, and ENCOURAGE the use of carpeting as a bass expander.
I like the design of the enclosure. I would still consider fans, tho... the ARC amps may not get hot, but I would not bet against it in an enclosed box.
what did you use to design the enclosure? it looks nice!

Re: Box design.. what do ya think? (bogus)
Llightwave. I've had my arcs sealed off before.
but i scrapped this idea. Ill be posting my new box design with my new subwoofer layout soon....

Re: Box design.. what do ya think? (Nevermind)
The thing about downfiring subs is that it loads the front of the subs, effectively changing the box design. Home subs that are downfiring are in boxes designed with this effect in mind. If you don't include the front-loading in your box calculations (which I don't even know how to do), then your box won't perform the way it was designed to.
