From the other night -- left number is dash and right number is kick panel.

It's our new SPL project... so far we haven't officially stated what is in it so if you know (shhhhhhhhh) -- but we'll have it at a show soon then, of course, have all the info out there!

It's mainly a burp vehicle and the absolute peak is 60 Hz but we have done pretty good numbers in the 40s range as well -- haven't really played lower than that as of yet.

We did have it up to a 165.4 as well with a few tweaks.

If it's the Jeep, those windshields don't like 165+. A guy up my way breaks a lot of windshields in his after about 164 they seem to let go more often than not. Hope you have a good source on glass.

Since we showed it out in the wild now here are the pics :

* Vehicle is a SEAT Terra

http://www.sundownaudio.com/misc/_Terra/CIMG6997.jpg
* Probably the funniest looking vehicle ever made.

http://www.sundownaudio.com/misc/_Terra/CIMG6998.jpg
* Two NS-1 amps

http://www.sundownaudio.com/misc/_Terra/CIMG6999.jpg
* Closer view. There are 32x D1600 XS Power batteries up top.

* Trophies from the weekend; 165.4 in IASCA and 165.8 in dB Drag SS 1-2

* Right now we have two layers of Audio Technix 80-Mil on the roof with a Sundown Logo "head liner" on top of it.

* Two completely stock Z v.3 18s in small boxes. We whipped these up quick to do initial testing -- we'll be making better chambers and better attachment methods for them soon.

* Through the port... more port testing will be forthcoming as well.

Dope. That truck looks like something they would carry Hannibal Lecter in.

That looks so much like the db revolutions setup here locally. He's doing ~164ish on 2 nightshades in a van, walled just like that, except port is drivers side. 4 3500's on it. He's peaking at 63 hz iirc.

We did some testing last night one vs. one woofer... stock Z v.3 compared to Z v.3 with ONE extra spider (Yellow spider pack). One on one it made a very substantial gain. Have to build a mate for it to try two subs (coming soon)



So we will also be making a set with TWO extra spiders (Red NS v.3 spider pack) compared to stock to see if it keeps going or tapers off.

At lower power the Yellow spiders were about 2.5dB louder than the stock black ones; but at high power only 0.1-0.2 dB louder. So this means we need to look elsewhere to make gains -- such as stronger motors, tweaking the cabin and box, etc.

Very cool information to have on hand, though, in case anyone is doing a lower clamped power class with a similar big 4th order :)

Derrick is still working hard on it in the mean-time.

Currently 6x Z v.3 15" Dual-1 with stock spiders and NS v.2 coils (pulled from the Yard Sale... these are not optimized for the Terra) on 3x NS-1 v.2 amplifiers.

Photo is from the TDH show in Virginia this past weekend; certified 3x dB Drag Score.
