I wanted to know if anyone has played with or modeled the SD-2 8" in a 4th order? Every review I have read on them basically points out they are a very solid 8 in a sealed box. I am a sealed box fan and basically want to pull a little more output out of them by going 4th order. I was thinking about doing a pair.

The designing a 4th order to get flat response thread and their sealed performance gave me some inspiration.

Any thoughts?
