Subject: first sub box pix
Date Posted: May 31, 2005 at 3:47 PM

I have been lurking and reading on this list for a month or so. I like this forum and it's moderators and have learned enough to at least try a box.
This enclosure will fit between the seats and against the back wall of a regular cab truck.
Sub is an Orion 'Hz Bass' 15 incher 1k watt. I plan on mounting it magnet-out and have holes for leads coming up through MDF at bottom of speaker ring to terminal cup in back.
Will begin glassing tonight unless anyone sees any problems I might fix or improve first.

that install looks great so far!

What are the plans for the enclosure, paint or some kind of material?

Okay, I put on two layers of fiberglass last night.

Is this surface too rough? Is there some additive or method to make it end up smoother? Seems like that would cut down on a lot of Bondo and sanding time.
After I put on four more layers, I will try getting it smooth enough to paint flat black. If I don't get a nice finish then I plan to cover it in black vinyl.

First off I like the nice clean install.   The enclosure  is coming along real nice.  Keep us posted with lots of pic's, we love pic's here.  Also FG is like a drug, becasue the better you get at it the more you want to do it.

When you put on the other layers of fiberglass try to avoid getting fiberglass and resin into the countersunk part where the speaker goes. In your first set of pictures it looks like the sub fits real tight. In your most recent pictures it looks like you laid the fiberglass so that it wrapped over the top and down into where the sub goes. That is going to make a lot of unnecessary sanding for you to get the sub to fit again. Other than that I would say you are on the right track.

How you gonna get that bracing out? Won't it rub on the surround?

i was just thinking about that, looks like the bracing is gonig to make it a 4-chamber enclosure! on the roughness issue, i think it's ok, you're just gonna need to spend some time sanding and aplying bondo... it's all fun tho!!!posted_image

Here are some more pics to address the questions

Speaker frame has a nice thick real cork gasket that holds the carbon fiber sub up enough that even at full excursion the rubber surround won't hit the inner ring.

The MDF bracing goes straight down whereas the enclosure wall curves out leaving nearly 1" of unrestricted space at the bottom and about 1/2" up near the speaker ring. I did let the brace touch the back wall fabric, where it can't be seen, in case I wanted to anchor it against the back cab wall.

M&M: I was able to use a cutting disc on a Dremel and just cut down the wall to free the glass and resin. Thankfully only nicked the MDF a couple times so sub should still fit snug.

That and it can get you really high if you don't ventillate, but not the good type, more like the old poisonous chemical high.

anyway, not to get off track cause I know that annoys people, It' looking great so far, it's too bad that they don't make solution to the pits and bubbles associated with FG, so we wouldn't have to spend so much time sanding, but it is always really really fun to actually mold a project like that and watch it take shape right in front of your eyes.

It's still really cool to watch someone else do it.  I love it when people include pics in their posts!

Keep up the great work and please post the finished results, I am anxious to see how this one turns out.  This one is far from MUSTANG, have you had a chance to see that disaster?  I would say that everyone should before attempting their first FG project, just so they know how easy it is to fill your trunk with cement, at least that's what it looks like.

eh? what did you just say?

 hey looks awesome, i want to make a nice FG box for a sub, but i have never worked with glass before, so here is a question.... are you just putting on layers of resin with no fiberglass mat? it seems like the more i see pics, people don't use the mat that much and only put the resin over fleece... is that strong enough for a box? if it is, i know that will help me cut costs of buying mat

Got the first Bondo coat on and sanded. Looks like I'll need to reform the outside edges of speaker ring.

I put a block of MDF inside the back wall for the terminal cup then forgot to press down the fleece to it when I resined. So cup won't have a nice flat surface to mount to, but I think I can still make it airtight.

'Thumbed' the whole thing and no give anywhere after 3 layers of mat. I think this is because of the curvilinear design which also made belt sanding much easier.

It looked like you used some strong wood glue to keep your sub ring and countersink together. I would recommend putting some bathtub/bathroom sealer (looks like caulking,can be found at Lowes/Home Depot) in between the glass and the cup then push it on tight and bolt it in. If you dont have any just use the wood glue and use alot and then just wipe away any excess that comes out the sides. Great looking install so far, NICE JOB!

I got my box sanded and the primer coats put on. I intend to have a body shop paint it but I'm going to glass the back wall of the cab and will have it all painted at once.
Sounds very solid, beyond what I was expecting!

hey bachsarte,  i noticed that when you wrapped it you stapled fleece down onto bottom ring.  did you eventually pull these aout or just cut them off.

I just left the staples in until I got the first layer of FG laid down then took a Dremel with cutting disk and went around the inside wall of the ring. When I was glassing I tried not to glob too much resin into the countersink and it really came out pretty easy, pulling most of the 1/4" staples with it.

After seeing Parts Express wanted $40+ for a circle jig consisting of a flat piece of plastic, I figured I could make my own. I used a shower stall liner for it's stiffness and then measured from bit to a place, anyplace, on the plastic and made a pivot hole. For the countersink I just made it 3/4" smaller than the outside ring and woodglued them together.
