Project, 16 8's in a Bandpass IB Clamshell...In a Stratus.

Title says it all right?

I've pre-ordered the subwoofers, I will get them near the end of may/ early june.

This is the stratus:

I will be tearing out the old baffle, and the front.

Making some kind of base, battery rack, and amp rack in the trunk.

Clamshell will go behind the seats, then I will seal the trunk off, stuff it with polyfill.

I bought E8's (sundown)

The final specs will look like this:

Re = 3.37 ohms (4 ohm nominal)

Fs = 34.9 hz

Qes = 0.5323

Qms = 6.93

Qts = 0.4943

Vas = 7.6 L

BL = 13.3 N/A

Mms = 127.7 grams

Cms = 162 um/N

Xmax = 12mm one-way linear (70% BL method)

Rated RMS Power = 200 watts

Depth = 4.25"

OD w/ gasket = 8 5/16"

Cut Out = 7"

Sealed Box:

0.280 ft^3 w/ F3 of 50 Hz (Qtc = 0.707)

Ported Box:

0.60 ft^3 tuned to 30 Hz

F3 of 25 Hz

They should be black instead of chrome.

This will be fun! //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

these will be powered by 1 or two sundown 3000d's

Heres my quick pathetic attempt:

I got started on the tear out, I'll probably remove all the batteries and amps today.

Im not catching the jist of this, looks like a regular sealed clamshell to me

 

[Rawr-DQ 10+ year member]

there is no back side, the clam will be sealed in the opening behind my seats. I gotta cut the metal out to make it fit.

The Clamshell will act as a bandpass from what I was told.

it's 2 chambers firing into another camber...the open area on the "face" of the box is considered a chamber...therefor it's a bandpss
