New personal best with one woofer =)

[sundownz 197]

155.1 dB - woohoo

This was with a "Monster" prototype woofer -- not a production speaker.

Interestingly... with all my tweaks to the Z v.2 prototype it was doing the same numbers per watt up to 2500 watts (I stopped measuring with the Monster at that point). So... I may be able to match this with a full production trim Z v.2 driver.

Previous best was 154.9 with an 18v electrical system and two SAZ-3000Ds on the sub... this time I am on 12v but with two SAZ-4500Ds (power is similar).

Some more pics of the setup :

I haven't played with front to back box positioning since I built the new amp rack (yah, slacking... I know) -- but I'll work on that a bit when I get time and see if I can increase this.

holy shiznit, that's nutz.

The box is really good for SPL, with all those mods.

EDIT: at what frequency?

awesome results

[sundownz 197]

53 Hz is my note with this box.

What king of dampening is that in your jeep and how many layers? Impressive score man, liking those prototype SAZ-4500D's you have there with the big Sundown image on them.

[sundownz 197]

One layer of Second Skin Damplifier Pro on most of the vehicle.

Thats a ridiculous score.! Do you think the kerf port helps increase your spl?

Of course, every modification or tweak to that box helps by increasing the score.

Oh yah... definitely.

Wow getting up there thats for sure, really good number Jacob

Get a 2150 and do a street B legal score

I think that would be louder than the current National Street B score here in Australia

[bigrank916 72]

Two 4500D's on the "monster" with a 155.1 @ 53hz! Damn, thats pretty wicked dude. Congrats with the new mark. When are we going to see this mansta JJ?! I keep hearing about it every so often but I know nothing about it, besides that you throw some impressive power at it and it keeps on tickin.

Ask Alan Dante how to get a single 18" loud lol. Mix together 28,000 watts, concrete, and a big neodymium subwoofer.
