I'm building a 36 x 32 WO out of solid pine 2x12's. Its sole purpose is SPL. The only reason it's not 36x36 is that I have to get it through my car door, because it will be my backseat for comps, and has to be removeable.

I've already got the wood rough cut, and the top and bottom are curing before I go drawing and getting the angles cut.

Thoughts?

1999 Escort Sedan.

No mods, except the 4" reduction in depth(front to back).

I'll be removing my rear seat, completely. Then sealing off the trunk with more 2x12's, and firing the (angled up) WO at that.

I'll diagram it here in a second.

shout get some good #'s
how about some pics, eh ?

we have our basic 10" 36x36 WO in our '94 Escort hatch--it sure peaks low--like 30-32 Hz!!  :D

nice  ;D


how many rms you gots on it?

It's built, and LOUD!

I didn't get any in process pics, as I was racing the weather. Got it pre-drilled(yeah, never did that before), glued, screwed, and siliconed, then brought it inside to cure, installed, and WHAM! CD's skip before I can get it loud enough. Oh, and it turned out being 32x34, I forgot about the 11.75" width of the boards.

WOW. My wife said it felt like her eardrums were fluttering back forth and she had some trouble breathing.

I've got to get finished pics on here, still.

How do I isolate the HU  from the vibrations to keep the CD from skipping?

sounds cool Jet.
think of isolating a Hard Drive to keep you PC quiet. stuff like rubber band suspension to gel mount.
Soft rubber grommets is something you could try. I never had much luck that way myself.

I cannot not play the stereo with any bass at all when my wife is in the car, your a lucky man.

It's got my old KFC-W2525DVC's in it, being pushed by the Xenon x600.1 (thanks again, 60) at 1 ohm.

It plays pretty darn solid down to about 38hz then starts a shallow drop off. A huge hump at 45-46hz (car's magic number). Audible sound clear down to about 18hz, but very quiet. It's only got a little over .5 ft^3 behind it, so I need to stuff it pretty good. I'm also going to run some bigger speaker wire. I've only got like 18 awg wire going to the speakers. I've got some 8awg on my workbench that I found last night. Will tear apart a pillow tonight and see about stuffing that chamber and swapping wires at the same time. I don't want to run it too hard with those small wires there.

I've also got to pull it out of my car anyways and make some more changes to the interior to get it louder.

Here's what I did:
-Removed bottom of back seat
-Folded backs down to bottom seat level
-Box on top facing into empty trunk
-About 6 inches of clearance between top of box and opening to trunk, 0 at bottom

So, if it's not raining again tonight, it'll come back out, seat backs will be completely removed, a couple changes to the exterior of the box will be made, and it'll be stuffed and given thicker wire.

The goal was to make a worthy SPL competition vehicle, for my area, but still be removeable for when I need to carry more than my wife.

Left pics at home.  >:(

Will bring tomorrow and post up.

I, umm...cracked my baffle, pretty bad. Speakers okay, but it really f'd up. Didn't get pictures(of the crack) though. Had to rebuild it. That was fun.

I didn't think 2" thick pine would split easier than mdf, which I can break with my hands.

Picture:


It's dirty. I'm sloppy with silicone and glue.

I'll get more once I get the outside finished and re-install it as it will be for competitions.

The black fabric is there, glued, to keep the polyfill from pushing on the cone. That's 1.25lbs of polyfill in about .5 cubic feet of space.

My 12" WO didn't vibrate.  I 'painted' all surfaces with wood glue.  Very solid when you knock around on it, no resonance.

Ok, I got the thing installed for showing this weekend. That was an adventure. I'll get some pics at lunch.

It's still the 34x32 version, just stuffed this time with 2.5lbs per cubic foot of polyfill, per speaker. It's a tiny bit louder, but a LOT tighter bass. Waaaayy less boomy.

I made the cover to take the place of the seatbacks to 'seal' off the trunk. Really, it's just used to kill road noise and as a second benefit improves the clarity of the bass, although killing SPL. For runs it'll come out, along with the rear deck speakers.

Pics to come after lunch!

What drivers do you have in it?

Interesting use of Pine- lol.

Other then that- Looks Great!
