So here's the deal. I have a Sundown 1200D, and Sundown 125.2 powering my setup. I will breeze over the 125.2 which will be hooked up to 2 sets of Polk db6501 components (2 ohm load) on each channel giving me a net of 100 watts to each speaker.

I am building a CUSTOM box for a12" TC Sounds LMS-R sub. This sub can handle 1k watts continuous and 4k peak. I can wire this sub to be a 1 ohm load which is a load my 1200D can handle (giving out 1200 watts).

I am trying to decide if I should port the box I am planning on building needs a port or not, and if so how long, size, ect I need it to be. I believe I correctly modeled the Treo TE sub I have now (in a ported probox) in the SPL image in WinISD. Please note the Green line is the ported 12, the yellow is a sealed 12" and the orange is the Treo 10".

I would greatly appreciate any help with this.

The internal height of all dimensions is 6 inches and there will be a cover (with holes cutout for the amps) that will go over the amp section so it looks all nice and neat. I also will be creating a spacer of some sort for the sub since the mounting depth the sub needs (7.15) is more than the current height of the box (6 3/4).

So as it stands the box is right around 2 cubic feet taking into account bracing which will be needed.

So if I port, what size, length, etc.

I really appreciate any help I can get on this.
