I can plug everything into sketchup if you'd like. I'm sittin at the girls house pretty bored and this would give me something to do lol

Yes please! That would be sweet!

I was gonna change the baffle a little, just a little angle, no real changes. just add 2" to the back side inner sealed width, and subtract 2" from the opposite side. If you could incorporate that, I would appreciate it!

Hell I appreciate it even if you can't! :drinks:

Thanks man!

Okay, so I came up with some new numbers, same design. See what you guys think of this one?

External: W 47" L 68" H 18"

Internal: W 45.5" L 66.6" H 16.5"

Sealed Inside:

W 7.208"

L 66.5"

H 16.5"

4.08ft3 x2

1.35ft3 per sub after displacements

Ported Inside

W 29.583"

L 66.5"

H 16.5"

16.89ft3 after port, sub, and bracing

2.81ft3 per sub

Port

H 14"

W 18"

L 6" - 3" external

14.92in2 port area per foot

252in2 port area total

46hz tuning

:popcorn:

just so you know the way the blow throughs are set up the tunnel effect is going to drop your tuning no matter how you tune it. so unless you like low low bass then id bring it up a little to 48 or so

also id try to make the port closer to 17 per.

but i like ground pounding so thats my opinon

then you should give more port area. id definitely bring it up to 17 or so

Already started doing it that way bub. lol What ratio are you trying to achieve? 2:1 I'm assuming. I noticed on your the figures you gave the area wasn't correct. So what are you wanting the internal areas on both sealed and ported sections to be at?

The whole point or me doing a blow thru is for the massive low end response it is going to yeild. I wouldn't mind having some playability on normal rap songs in the upper span, but full tilt my goal is for 150s in the lower 30 hz range and just kill all the way down into the mid-low 20hz range...

And yes was going for a 2:1 ratio within the space I have.. It may be a little smaller than it probably should be but a stepside bed only has so much room

Laying frame soon.. System has to wait

So does the numbers I put down look good to you? If so I'll finish up the Sketchup and post it at those specs.
