Jacob's Wall Build Log

[sundownz 197]

Got this truck through some horse trading... current setup was tested to do 154.3 dB @ 61 Hz with two Z15s and a clamped power of 5000 watts total. I want a more efficient setup so I am tearing it all down!

Some pics of the current setup with the cap off and starting to tear down :

Old wall has a great baffle - 7 layers thick - but the outside is too thin. It is one layer of MDF with super dense foam sandwiched between that and a thin layer of wood (I had that peeled off before the pics). It does have concrete above the front chamber, though, so that is not too bad.

All in all I think it could be better so I am going to rip it out!

looks like a fun project

[sundownz 197]

Not 100% sure what I'm doing yet Once I get it out I am going to take a good look at it and consider my options. I have thought about some sort of band-pass but I may end up going back regular ported wall.

* Everything out of the back

Taking out the concrete is going to be difficult... has a metal mesh in it.

wow what did you give up to get shawn to give that up. he never parts with stuff easy.

[sundownz 197]

Concrete is OFF... working on the foam. I think I can re-use the shell and just layer it up with actual wood

We are also working on a 4th order wall for 12 x 12s today... so we are busy!

Have the one side and about 2/3 of the top sanded down smooth with a grinder after foam removal... got most of the foam off of the other side so I can grind it down soon too:

[sundownz 197]

Top is 100% cleaned off... broke off a grinder disc on some of the concrete residue which shot off, hit my finger and leg (ouch), and then broke a fluorescent light *laughs* But... I got it done!

[acex3a 5]

wow looked like a lot of work.

whats with all the box on the left?

[sundownz 197]

There are like 10 boxes to the left Which one? They are just various boxes we have built up over time.

Tell paul to quit drinking and get to work or you not get any thing done. looking good though. i should post some pix of my new build somewhere.

[sundownz 197]

The last side is cleaned off... starting on the inside of the box:

Part of the floor had a bit of a hump from moisture -- side closest to camera -- had to grind that down so I can slide the baffle in.

[sundownz 197]

TOP of the box is OFF... back wall slid back to where I want it.

I have around 38 cubes to work with in this position.

I can use the back wall... it is 6 layers of MDF with 2x4" lumber bracing, very sturdy.

[sundownz 197]

Framed the back wall into place on the front (also framed into place on the back as pictured before) -- starting to frame in to place the woofer baffle in :

Back chamber is 5 ft^3 before the displacement of the 2x4" lumber + any other bracing I decide to add. Figure I'll end up with around 1 cube per driver as I plan to reverse mount the subs (no sub displacement).

[sundownz 197]

Cross brace finished for the baffle... just need to build the baffle itself now :

Looks pretty strong to me

That looks like a lot of fun. Cant wait to see more of this.
