First off.. thank you to everyone so far with the emails and posts helping this newbie with this project.. I really do appreciate it and can't wait to take pics within the week when it's all completed. Now to my question.. I literally just walked in the door to finishing my fleecing, and doing my resin. Thank god for the respirator!. Ok, so I pulled the fleece really really tight, staple gun'ed it around the edges. Looked awesome.. then I took my resin that I bought from Home Depot.. was the bondo brand I think. I did exactly what it said on the can.. 14 drops of hardener per ounce I think. First I only used 2 oz's.. I realized that it goes quick and fast.. so after I used that up.. I poured 8 oz's.. with 100 or whatever drops per hardner (I did the math and did the exact amount of drops, I just forget right now how much it was). So I covered the entire fleeced area with resin with my 50 cent brush, and literally SOAKED it by the speaker rings, and edges of the box. So, I looked inside the box, and the resin didn't soak through really. But the inside of the fleece is dry, but it's already harding when you tap it because of the outside starting to cure. It's soaked from the outside though. So my question is.. is that normal?.. and if so or not.. should I resin the inside of the box as well or is that pointless being it really can't soak into much material being the outside layer is hard? Thanks again for everyones help!!.

go ahead and resin the inside also because tht is going to give it extra strength. that is normal by the way. if you just resin on side your box will only be half as strong as it could be ------------- what!?!?! you want some??

ok sounds good. I'll wait for the outside to dry I guess first.. then i'll do the inside. How long should I wait?.. 2 hrs?..

thats exactly what happened on both my boxes. i just liberally soaked the entire fleece on the outside. then when that was almost all dry (about 1 1/2 hours) i soaked the inside as well. but even if it did soak all the way thru the fleece id still put a layer on the inside just to give it that much more support.

I usually do a 2 to 1 ratio, like 3 layers on the outside, 6 on the inside with more on the inside for internal strength. Its extreamly strong. I jumped up and down on one of my boxes and it was like jumping on solid rock. As for the fleece, soak it, you'll want it to be completely saturated, that will give it the best possible stength.

go big or go home..... in 5 years, when alpine releases their z-type 8000 watt subwoofers with 6 voice coils, you'll understand.

If you add a little acetone (buy it at homedepot) to the mix up of the resin it will thin it out, allowing it to soak thru the fleece better. But that is normal, you just REALLY REALLY dont want that to happen around the MDF ring. IF it did you gotta fix it or your pretty much screwed. Also, a good thing to do is hold your box upside down, pour resin into the box around the ring, then move the box around to get the resin all up in the spot where the fleece and mdf meet. Hope that helps. post pics when done !

i second that notion.... if the ring isn't tight... yer screwed. I try to cut the fleece so that the sub will sandwich it betwwen the ring also, I'm a little paranoid about these things -------------

well when I did the resin on the outside, I soaked.. and I mean SOAKED the rings to the point that I was worried if I did it anymore that the fleece would get too saturated. If the rings arent adhered to the fleece, i'd be shocked!.

9 layers was for 4 10 in HX2's, not the little ones, the 3110 ones. A friend of mine was like "Hey, I got some kool looking subs from this shop, do you know if their any good?" I almost passed out when I realized what he had. Needless to say, 4 10" HX2's blew apart the 5 layered box we origionally built, after that we went bizerk and threw on 4 more layers, and enough resin and reinforment to park an aircraft carrier on. I generally use just 6-7 layers for my more common 2 sub boxes, but I'm kinda weird, I insist on having more than 2 subs, I hate having just 2, because of this I build my boxes between 7 and 9.
Oh, defective, that was a good one, the 6 voice coiled sub. I wonder how big the friggin magnet would be haha.
PS, a little tip for the rings. If you make those prefab looking ones like you can buy off w/e that one site is you can get screwed if they dont cling. For this reson make a third ring, use it between your mount ring and the fleece (screw them 2gether and resin all around them) that will solve that possible delima

not to break all your hearts but resin by its self is not srong at all. and it is better to use the bare minimum resin for the job. one trick you can use to help it soak is to take a bodyfiller spreader and squeege the resin after you brush it on. this will help push the resin thru the fleece or whatever.
when pouring resin into the inside of the box, you will want to have a thickening agent or something to make the resin strong in there as well, like some torn up chop mat or something like that.

try using duraglass... (or hairy glass) that would kill two birds with one stone
