Not the box you were expecting? Hahaha...

Hey, Ive been building sub boxes for quite some time now, and I wanted to see if I was actually any good at it, cause I think they are almost perfect in every way... not to be stuck up, but I put a lot of work and effort into it.

So here goes!

Please rate the box ive built for a Focal Utopia 38 WX Subwoofer. It will be mounted *** out, as in, the magnet being external.

There is still more to be done... In these pictures, these are the processes that I have undertaken...

I cut the wood... Obviously.

All on perfect angles, I am 100% sure of this... it took me quiet a while.

When constructing the subwoofer box , i used the best wood glue I know of... I had smeared the glue on the entire edge, gave a light scuff to the recieving part of the wood, and clamped every joint.

After each side was fitted, and glued, I had proceeded to predrill holes on that edge... countersunk... obsiously. Sanded all the edges smooth.

I then drilled holes for the 2 4" ports, and 18" Focal subwoofer.

Once the box was constructed like this, I had sealed the interior of the box with a clear sealer, lacquer sanding sealer.

Once sealed (a couple coats) I had siliconed the joints. I left the one end of the box off, so that I could have easier access to all area's of the subwoofer, once the ports where installed, which I will talk about next...

The ports, have the holes cut with a router, perfectly the right size. I had sealed the edge of the port that would sit beside the PVC pipe. I then used some Polyurethane Glue that is supposed to bond anything as well as epoxy glue's, its waterproof, and expands when it dry's, therefor keeping the box air tight. The underside of the box was siliconed around the ports, or will be once the port glue dries, which is where I am sitting now.

Watching glue dry... isnt this grand... look at all the time ive wasted just creating this thread :\

Anyways... once the ports are dry I have the following steps remaining...

Screw holes to accept manufacturer supplied T-Nuts. (This is also why I had added the extra peice inside the front, top and bottom corners inside.)

Attached the remaining side, glue, screw, fill, silicone, as to be like the rest of the box.

Sand wood filler on holes

Sand around ports to remove excess glue

Router the edge of each of the ports, rounded, hoping for less of a port noise.

Im going to do something with the interior of the ports, not quite sure, but do not want the sheen inside that is currently there.

The 2 wires from the subwoofer that will be connected to his amplifier will be red, to match the super sexy exposed magnets. They will route back inside the box, either at the top, bottoms, or one on each side of the subwoofer, not sure of orientation as of yet... Those penetrations will also be sealed.

He wants black matte carpet, so that will be super sticky spray glued down, ofcourse 3M.

I will trace out the subwoofer, and remove any carpet that may between the subwoofer, and box, and replace this with foam/rubber tape.

Plug it in, and hope for the best.

The box is exactly 3.04 cuft, tuned to 38-39Hz.

Ok, wonder if my ports are dry? Hahahaha.

Hope it was worth the read, and pics, I will post more pictures until completion, was hoping to take beginning stages, but I wasnt wait for glue to dry, and being bored :\

Peace out.

 
Im not 100% sure... that box fits in snug in a 98 Integra... that he drives... It was the best I could do with that box size...

 
Its 2.5" trust me, I measured it. Dont forget the flash going off probably kills the shadow.

How far SHOULD they be, and will it make a big difference overall?

I can always cut them down, and add a bend...

 
great craftsmanship. I am a slot ported kinda guy but thats me. I like the even lines on the entire enclosure.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

 
I would have done that, but I was unsure if he would leave the magnet on the exterior, if he turns it the other way, the ports would touch... This however is the way that the manual orientates the ports... I wanted to keep it to thier specs, so to hear the true quality of this subwoofer.

One thing I am wondering about the ports... would there be a performance issue carpetting over top of the ports on the exterior?
