Jacob's Jeep : 4x SA-12s + 4500D = 153.8 dB


Recommended Posts

Planning to run this setup for nSPL Finals this weekend... needed to stay under 5000 watts on the nSPL clamp meters. On my meter it clamped exactly 4000 watts last night which should be 4700-5000 on their clamps.

Tuning is in the high 30s and peaks at 47 Hz... tuned to 30 Hz and also peaking at 47 Hz it was about 1.8 dB quieter but still not bad at all, IMO. I plan to try cutting the ports down a bit more to see if I can get a tad more from it on the meter... may or may not get that done before the Finals event.

Best score with just me in the Jeep was 153.8 and with Nick from Stereo Integrity in it as well we got 154.0 dB -- sealed on the dash.

* One SAZ-4500D chilling out on my amp rack. Running at 0.25 ohms for burps -- re-wires to 1 ohm for daily.

* 3x 6" Aero-Ports... box is a hair over 6 cubes with my shortened ports. Almost exactly 6 cubes with full length ports. Team Sundown Derrick build this box for me.

* One NSB-G3100 in this corner.

* Added an XS Power D3100 this morning... score did not increase but my voltage doesn't drop as bad on burps and I'll be able to play music longer of course!

* Standard DEKA starting battery.

This setup does keep gaining with power... with the full length ports (which are 1.8 down at this power level) I have done a 154.7 before with this same setup running two 3500Ds @ 0.25 each.

I plan to try more power after the show... and eventually to try four Z v.2 12s with single spiders. I tried some Nightshades a while back with 3 spiders and it was actually quieter than the SA-12s -- so I think this box needs a much softer compliance.

nice stuff! try getting that wire away from the port, and get that tape off the port. your costing yourself a tenth or two. awesome stuff!

It was identical with or without the wires and tape and also without the second battery in back -- last night I had only the NSB in there and it was exactly the same.

I have seen gains moving wires completely out of ports... as much as 0.3 in my "Magic Box" -- but it has no effect on this one.

Email to [email protected] works well.
