I would like to see some fiberglass subwoofer enclosures and the way they are made, tell me a few of you out there know something about them?

I am looking to make something very smooth and contoured in a style similar to the c-5, would love ot make it out of fiberglass if I can, but I don't know alot about how to work the stuff. Or the structural requirements of fiberglass for a sub enclosure.

Help a brother out!

 

I am almost done with mine. I dont know if this is what you had in mind but mine is very basic. Here are a few pics of the beginning and prep work. At this point I already have the mold done with the top attached. The top is also finished and have already added the Bondo to the ring and sanded it out. All I have left is to carpet it which will I will do this week.

Prep - 2 layers of masking tape and 1 layer of foil tape.



1 layer of fiberglass to obtain the mold. Lift out when dry (2-3 hrs. to be sure) and build up approx. 3-4 layers more inside.



Create a top. I did one with a ring to face a little forward and to give it better bass response and to keep from the basic "flat" sub box.



Make a support for your ring to hold in place under the top for fiberglassing and bondo. When done with the molding and top. Replace the mold back into the well area in the car, over lap the edges with fiberglass (one layer is fine) place the top on before dry. Carefully pull out the box when completely dry and turn upside down to finish fiberglassing around the edges, approx. 3 layers.







The bondo adds to the overall strength and allows for a smooth curved sanded finish.

The box is very strong and hits hard. The top is made of 3/4" birch wood. Again, all I have left is to carpet it. I will also mount the amp to the back wall and finish the project with a cover for it.

I cannot stress enough how important it is to mix the resin and hardner well. Scrape the sides of the bucket with a mixing stick over and over. Practice first before you start your project. It will pay off in the long run.

This box cost me $120.00 in materials. Not bad for a custom box if you like to do things yourself ;)

I have been quoted in the past for this type of set-up from $700.00 to $1,500.00 :crazy:

Good luck and have fun with it. I will have lots more pictures on my site in the near future.

 

What a killer install and pictorial you have put together here! Thanks man! So when do I get to see the finished product?

 

Thanks :cheers: ....I will carpet the box on Sunday. I ordered the carpet from selectproducts.com and received it yesterday. I will post a pic to this thread on Sunday.

 

What was the total volume of the box?

 

Cool, I will eagerly await the new pics man! Impressive!

You know, now that you have made such a killer enclosure, you have really raised the bar for me . . . I will have to do something at least as impressive, hope I am up to it!

 

Very C :cool: :cool: L .... Conquer got a couple of my speaker mounts, maybe I'll fly him out to make me a sub box. :lol:

 

Very nice work. You did a great job. I would like to do something like that but I would like to do it with two JL 10W6s or two 8W7s. How much power are you putting to your 10W6? Or is that a 12? I can't really tell. :cheers:

*edit - Nevermind about the driver size question. I just read your sig. :crazy:

Approx. 1.00 - 1.10 cu. ft.

Im sure you will do a fine job. The key to all this is Patience. Take your time and do not try to complete the job overnight. Fiberglass is put together in stages.

Thx!! Love those mounts....

Thx!! :cheers: ..... I would go with the 8W7's. They might not move as much air volume as the 10's (only 4") but those W7's are unbelievable!! Those would sound really good and tight and to me, better then the 10's. You could have the 8's come out the top of the enclosure each at opposite angles. That would also give you more volume in the box. Either way, I know you will come up with something great!! I saw your thread some time back on your enclosure that you build..... very nice job on that!! :yesnod:

**************************************

Well.... like I said, I will post the picture of the box on Sunday when I carpet it but you all will have to wait on the rest. This has been a weekend job for me and has moved along slowly.

I am also going to add the Jl Audio remote bass **** in the ash tray of the dash. I will fiberglass a mold and flush mount it, then black vinyl it to look factory but will still be able to close the main lid to it. :)

 

Yeh, Conquer's just been waiting in the wings for a couple of months, and then comes up with this. Kind of like when the beatles came out with Sgt Pepper. Just blew everybody else out of the water. AAANNNDDD he's a law enforcement officer, he ain't gonna be hasslin the kids wit da hard hittin boom sound now. :lol:

 

:lol: no hasslin.....just might stop'em to see what they got :) :D

 

Long weekend and I am heading out of town, but you can bet as soon as I return I will be eagerly expecting pics of your handy work!

 

Fiberglass is fun. Takes alot of sanding to get it smooth to be painted. I sanded my arms off to finish my trunk in time for the show.

As far as W7 vs W6, personal preference. The W7 bass is very "heavy" deep with alot of impact. Sometimes the sub is not fast enough with certain material but that is personal opinion. They are good subs.

 

Nice work, Conquer :thumbs:
:cheers:
