Enclosure as a seat

[Broke_Audio_Addict]

I'd do a layer of a more rigid foam for the bottom layer so there is some support still.

Cool idea.

I like the sound of that Broke.

I'm doing some numbers right now.

Should also make for some good demo's with the ladies

Could be interesting if i could pull it off.

So here's what I came up with. This is just rough rough rough. Nothing designed, nothing in stone.

4 DC Audio M38's. Require approx .75 ported and .35 sealed.

4 x .75 = 3.0 cu ft ported +.4 (sub displ.) = 3.4 cu ft ported

4 x .35 = 1.4 cu ft sealed

My seat dimensions are as follows:

56" wide

22" deep

10" tall (front is 11" and rear is 9")

If I went single baffles it'd look like this:

2:1 Ratio

Sealed: 54.5" wide x 5.25" deep x 8.5" tall = 1.41 cu ft sealed.

Ported: 54.5" wide x 14.5" deep x 8.5" tall = 3.88 cu ft - .4 (sub displ.) = 3.48 cu ft ported.

Using a precision port, I used the calculator on their site. I'd be looking at a 6" port about 7.75" long for a tuning of approx 42hz

Also this is with a double sub baffle.

As a design idea I'm thinking sealed up front, with a plexi glass front wall. Sub cones facing forward. Ported in the rear (obviously) and then the port in the center going through the sealed section. Obviously I'll have to account for that in the sealed section, but I think I can do that. I can also do the floor of it in fiberglass to gain some of the width of the 3/4" material back. I could also gain by using a single baffle but I don't know if it'll gain me much, because then I go from zero sub displacement in the sealed area to having to account for the 4 of them.

So it could maybe happen. It's certainly a thought now. I hadn't done much thinking about it before.

As far as the seat goes, my thought was do it like a boat seat is done. Take and make a wooden panel for it the size of the enclosure. Glue some foam to the top of it. Then have it covered. I would have to decide how to attach it but I could probably do it through the enclosure. Do the enclosure cover in the same color or a contrasting one.

Now my mind is going nuts!

Would you wrap the seat and enclosure all in one? I dont know if it would be too flashy for the build goals or what but with the plexi there is always the option of LED's. This looks like its going to be an awesome build.

[scooter99]

I don't know. I think separately for ease of it. I won't be doing the wrapping, it'll be a shop. I'll pay to have it done right. I'm not there yet. LOL

Leds are a possibility for sure. Almost a must if you have plexi, I think anyway.

I thought about this idea as well before my build but I didn't want to get THAT involved and deep into it. I also wanted the option to put everything back to stock in a few years when I trade up for a new truck. I ended up fiber glassing the floor shape and down firing the subs.

That's my build but I'm very interested to see if you go for it what you come up with. Good luck man

[scooter99]

I will be doing something that's for sure.

I wish I had the room under my seat that you chebby guys do. That would make things way easier for me!

[tboorn]

i had seen someone asking about a similar idea on FB a while ago and thankfully i saw something i thought was so awesome i screenshotted it....

Not exactly what you were thinking but its a seat and a box haha. The guy who built it said that he actually was able to still get the truck inspected and pass with the box/seat still in, used the original bolts and seat belt i guess. I thought it was pretty fucking awesome
