Got this truck through some horse trading... current setup was tested to do 154.3 dB @ 61 Hz with two Sundown Z15s (mid level 1000 watt RMS rated subs) 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!
-----
* Everything out of the back
* Baffle Out !
-----
Concrete is OFF (not easy... it had a steel mesh in it)... working on the foam. I think I can re-use the shell of this box for the new setup if I can get all of the foam off.
-----
I think I will try a 4th order first and see how it works once I finish strengthening the outside.

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:

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!

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).

Does not really have a loading wall, just small build outs on the sides -- but that setup was pretty darn loud.
If it doesn't work out I am going to set it up so I can take the top of the enclosure back off without totally destroying it to re-adjust the box volume, alignment, etc.
