Sealed on the dash video :

Outlaw score best... 150.4 dB as of now. Same frequency, 53 Hz.

Uploading Outlaw video shortly.

Setup is pretty simple -- here are a few still pictures :

The platform for the box consists of some random wood scraps... I didn't want the subs firing into the amp rack / amps so I raised it up a bit to about 0.75" under the window line.

Could probably gain a few tenths taking the wires out of my port... but I haven't gotten to the optimizing phase yet. We just built the box today and dropped it in!

lol damn for 8's they sure can output some good numbers

Box Tweaks to be tested :

1) Rounded corners

2) Wires out of port - replaced by brass threaded rod

3) Port carriage siliconed to box and port also siliconed to carriage

4) Duct tape instead of rubber gaskets... the hole cut outs with a bit off so this may help

150.4 db from some 8's

thats very impressive

... make that 150.0 with two 8s

Duct tape FTW + our other improvements (round over, sealed up port, wires through brass rods).

ON TO THE SCORE !

I'll work on actually taking a video shortly and backing the score up... our camera man Derrick wasn't here today to get it the first time

Thats ridiculous!!!!!!!!!!!!!!! I dont need any more woofers but i might have to pick up a set just to have in the collection

Video of 150.0 dB sealed on the dash score

Kick panel score also gained 1 dB - now 151.4 dB:

I still cant belive there are no comments on this. that was bad ass. 1760 watts on an 8

damn, my friend is gona run one of these in is s10.. should kickassss

Those 8's are beast! Great Scores

You know what dude, i Effing quit.

you broke out a 50 on a pair of 8's in a jeep, I'm done.

Good work there super guy.

Im trying to talk my friend into buying these since he wants to run 8 or 10 - 8" subwoofers in his car, its hard trying to break people away from mainstream products.

can i trade my 2 18" bls for some of these jeje jk

its impressive what you have done

awww man. I can't tell you how right you are on that.If I talk about a sundown to someone they look like their dazed and confused. like what is that

but back to the topic. those 8's are rediculous

Hey Jake, could you run a test with your pair giving them the recomended 400 RMS each and with the recomended tuning. Just wanna get a rought idea what they can do with your recomended enclouser size and tune.

same here i wanna do 4 on 2000d

I would love to grab a pair to have a play with, but the shipping to Australia would probably be 2X the price of the drivers

Well done Jacob, simply amazing stuff

You need an Australian distributor, even New Zeland has one from what i hear now (DC?)

I had spoken with someone in Australia before but they didn't come through.

Jono

SPL per watt testing (total power... divide by 2 for each woofer):

330 watts = 143.9 dB (HU @ -10 sub control)

430 watts = 144.8 dB (HU @ -9 sub control)

580 watts = 145.6 dB (HU @ -8 sub control)

750 watts = 146.4 dB (HU @ -7 sub control)

990 watts = 147.2 dB (HU @ -6 sub control)

1290 watts = 147.8 dB (HU @ -5 sub control)

1710 watts = 148.5 dB (HU @ -4 sub control)

2260 watts = 149.1 dB (HU @ -3 sub control)

3010 watts = 149.9 dB (HU @ -2 sub control)

Going to try -1 shortly after they cool off... I dropped a 4500D in the Jeep instead so I am a bit more flexible on power if I decide to put something different in for any upcoming shows. So I have the potential to put more power than I have before on them now.

-1 was too much with the 4500D -- woops
