4- sa-8 enclosure

Recommended Posts

First off, to those who have helped me with my mid bass thread. I'm still planning/ listening as time allows.

Thank you, to those that have offered help , you know who you are, it's greatly appreciated and I should have some updates soon.

O.K., I figured I'd better get off my ass now that i have some time and get the subwoofer box on its way.

This is an enclosure for 4 sa-8's, 3.6 c.f. (net) tuned to 33 hertz with 52.875" of port. It will be driven by a sundown saz-2000d @ 1 ohm.

This is going in my 2000 ranger extended cab pickup.

Everybody has seen enclosures with kerfed ports, but not like this one I'd bet.

I was originally going to do a double kerfed port, but in the end it wasn't worth it from a stability standpoint.

I found a good price on some 11 ply Baltic Birch so I picked up 2 sheets.

After working with this I'll never go back to MDF again.

It's not void free, but it should be fine.

This was my helper, until the saw fired up. (neighborhood buddy, My brother has 5)

I tried to kerf some mdf, but didn't have much luck with a 2" inside radius., so I went with what I know.

Steel, (11ga.) which I "nipped" into these radii ( 2" i.d., 2 3/4" o.d. and 7 1/4" i.d.)

I don't have a router, only a circular saw, jigsaw and a drill. I need to route out some material so the steel kerfs would be flush with the surface of the wood. I then got out my "circu-router" and proceeded to do just that.

I cut the first hole and thought,"I'd better check the fit (woofer porn to follow).

I forgot how big the motor on the sa-8 was until these pics.

it fit quite well.

It looks like it's time to mow the driveway again. :rockwoot::thanx:

Let's start getting this together. I don't have the patients to wait for glue to dry, so we glue and screw.

I figured I'd paint the port while I had a good angle at it.

I may go with a charcoal instead. It depends on the fabric i choose to cover it in, black or gray, like trunk carpeting. I haven't decided yet.

A few more panels glued and screwed.

It was getting late, so I stopped taking pics til I was almost finished. I will paint the area around the woofers to match the port, gray or black.

I can't wait to hear this. I've got the last of the electrical coming on tues.. I still need to do that, 4 runs off 1/0 kolossus flex and some 4 awg. runs as well as a new alternator, big 3 and weld up an amprack/enclosure frame.

I hope you enjoyed the pics.

The inside of the enclosure is 11 3/4" wide.

The outside dimensions of the enclosure are 48" x 17" x 14".

Thanks everybody, for your comments.

I think I'm going to replace the countersink screws with some button head screws, they look pretty stupid sticking out like that.

Thanks J. I think they look retarded sticking out like that. :suicide-santa:

I've still got allot of work to do in order to get the box in the truck. :faintthud:

Then there's still the front stage, that I haven't had time to mess with. :5shots:

How are your doors coming along?

I haven't seen any updates in a while, believe I'm subscribed to your thread.

I think the screws would look better not painted.

I am slowly but surely getting the doors done. I will start posting pics soon.

i like the port idea. seems much simpler, but more cost. Why the hell do you need 4 run of 0 gauge and some 4 gauge for 1k watts?

Lol, what part of Sundown SAZ-2000 at 1 ohm didn't u understand? ;)

And there is no such thing as overkill. :peepwall:

I'm a steel fabricator by trade, so it is cheaper and easier for me.

Shit it's free and the only cost is my time, come to think of it I was on the clock when I "nipped" them so I guess I got paid to do it.

Why 4 runs of 1/0 you ask, because I 'm only doing this once.

I'm running 1 positive and 1 negative for the saz-2000d

I'm running 1 positive and 1 negative for everything else.

I can pull 3 sets of 4 awg. (pos./neg.) off of the second set to run a jl 300/2, saz-125.2 and an undetermined amp to run the front stage when I go active.

Looks good man. I kinda like the bolts. I would leave all the metal parts unpainted and polished up with a sander. Would be a cool contrast I think.

Thanks Lance.

If you saw how far the countersunk bolts actually stick out you'd change your mind.

I'm going to change them out for some stainless one's.

I probably should have made the radii out of stainless now that I think about it, oh well there's always next time.

I hit one of the local fabric shops yesterday looking for something to cover the enclosure with.

I've done vinyl in the past, but thought I'd change it this time.

I found this fleece and felt, nothing else really caught my eye.

I wasn't really happy when I left the store.

gallery_11963_485_1282865.jpg

I picked up some paint for the port and the area around the woofers.

I also got some super 74 adhesive.

I don't like the look of the the countersink screws that I used, so I picked up some stainless steel button heads to replace them.

Today I went to another fabric shop and ran across this microfiber suede.

I was much happier when I left with my this material.

I also hit an arts-n-crafts store and got these. I hope it turns out as good as I have it pictured in my head.

It should look like this, but black/silver instead.

Looks good. I was driving around today wondering how I could use steel in my own box, since working with metal is what I'm good at. Keep it up.

i misread, thought it was the 1000d, not 2kd.

Love the kerf with metal! Would countersinking the screws be an option.

The design for the box looks great!

No problem, Thanks for looking/commenting.

I don't know if you read my response or not, but if you didn't:

Thanks.

The radii are only 11ga. (~1/8") so I can't really countersink them.

I made them about 2 months at work and used the smallest punch/die we had, 5/16".

I could go to a #8 countersink screw instead of the #10 that I used.

If I don't like the button heads I 'll try the #8 out.
