4-5 cubes is what most folks use on the 18s. Tune to your taste between 30 and 40 hz.

There will be more detailed pictures when the motors arrive -- 3-4 weeks I estimate.

Yes ! Some pictures vs the SA-12. This thing is MEAN... cannot wait to get it in a box. VIDEO ! We had a 1500D @ 1 ohm on it... not using all the power, but we got on it pretty hard.

That is an adequate box size if you must use them sealed. They will still do alright -- but it's not optimal.

Pretty much.

I sheared the aluminum former in two -- didn't break any glue joints or thermal the coil. I suspect I bottomed out my triple joint ring on the top plate hard enough that the shock broke off the former. Of course I had 2000 or so watts per sub at this point too -- something has to go eventually. I will add a LITTLE more rearward clearance on production models so even doing that will be slightly more difficult.

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

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.

They are running behind the end of October ETA... I will post any updates as I get them.

SOLD OUT. If you have not already talked to me or placed your order then you will have to wait for the next run more than likely.

Production coil samples are not here yet, so no.

75% of the e-mails I get require me to answer them myself as nobody else knows the answers.

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

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

Video of 150.0 dB sealed on the dash score

... 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

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

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!

Outlaw Video : 150.4 in the kick panel also at 53 Hz.

One 3500D @ 1/2 ohm.

Sealed on the dash video : Outlaw score best... 150.4 dB as of now. Same frequency, 53 Hz. Uploading Outlaw video shortly.

So far in my testing... I've gotten 149.0 dB from my pair of SA-8s @ 53 Hz in my Jeep. New box layout that I've never tested before... sub forward / port back

Oldest e-mails in my box are from the 23rd... so I am getting closer to caught up !
