Van flexes like mad and I seem to have two peaks. The vans usual one @ 42hz then my port... which is a little lower than I wanted it to be... actually a lot lower... lol. 29hz is my other peak, lol.

So, here are my scores.

New start for the Windstar...-139.19-%40-29hz.jpg
New start for the Windstar...-144.02-%40-42hz.jpg

I can't get them to full burp for some reason. Seems like a loading issue. They start off moving nicely then seem to compress and no matter how much I turn it up it doesn't gain. It did this @ 1/4 gain when before I could go max and still gain on the meter. You can literally hear is stop gaining and the subs slow and lower in excursion.. really strange, never seen it before...

Guess I've got lots of testing to do. I'm going to find a way to raise the peak to 34hz (likely cut the port down). 29hz is WAY LOW but man everything flexes like never before. lmao

Going to play around with shrinking it a bit. 8.6 might be a little too much. lol

Kicks the crap out of music, gets real low... I need to bolt it down. lol I think with a little more work and some testing/tuning. It'll do fine for my daily box. I'll worry more when I make the SPL box. I just tried burps to see what it would do. It doesn't like them much, lol.

I'm sure the numbers will come up a little when I get tuning back around the 34hz area.

Not sure if more power is the answer. I think I've gone too big but always willing to give more power a try. It doesn't seem to like the power I have now... not on burps anyway.

Nope, I was talked out of the sliding port idea, but I suppose I still could, but the noodle is sort of resined to the wood on that side... I've got lots of wood.
