154.3 with ONE Nightshade 15!

[sundownz Pro Seller]

* Four SAZ-1500Ds installed

* First burp - HU Sub Control at +0

* Second burp - HU Sub Control at +3

* Third burp - HU Sub Control at +3 / One Hour Charge time on the batteries (lunch break)

Not too shabby //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Pretty standard ported box - peak @ 53 Hz. My recent addition of Second Skin Damplifier raised my peak from 50 to 53 hz.

My previous best score with a single Nightshade was 153.0 dB with two 3000Ds (similar power to what I have now) but without the Dampener. On lower power I gained 0.9 total with the current amount of dampener and that seems to have risen to 1.3 dB with more power.

whats your impedance?

*laughs*

I can share my SPL results //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I'll be taking it to two shows this weekend... one is a MECA show so I'll have a head-rest number on 4x 80-amp fuses.

whats your impedance?

Dual-1

1/2 ohm per 1500D.

For two 3000s I had a Dual-2 and each amp at 1/2 ohm as well.

Rise in this box is low but not measured with this specific setup //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Nice,

Ya... I didnt care much for the box impedance rise I was just wonderin what each amp is seeing.

That is actually a lot of power

The wire is a mess... it was neat for a little while until I changed the amp setup 10 times, haha. I will be re-building the rack again for four 3500Ds to power two subs so I will neaten it up again then.

3.5 cubes tuned in the high 40s with 96 in^2 of port area //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

how much of a difference does that pvc pipe at the top of the box make?

Indeed - quite a bit of power //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

jacob have you ever though about testing numbers on a daily box.

something around 32-34hz just to see what a single 15" would score in that setup.

im sure there are some people here (including myself) that would love to see what a single would hit in a daily enclosure, as thats what 98% of the people on here have.

just a though, i figured if you had an extra box lying around you could give us some numbers, if not no worries.
