i came 3rd in my 1st competition with them yesterday with a score of 150.1dBs.. the box used was poorly tuned and installed last minute for the competition.. no testing was ever done..

2nd Mohan Ramlochan 152.1

3rd Rene Roberts 150.1

4th Shameer Baksh 150

5th Adrian Boodoo 147.8

the 1st place score was made by a walled off Mazda 323 hatch-back, running a 7000W Cactus Sounds amp and 2 15" Cactus sounds subs..

2nd place was made by 2 95series 15" Digital Designs subs powered by a pair of 5000W Atomic amps!

my personal goal is to beat those DDs

Those things are so sexy. I can't to get mine. I am only getting one with 1000 watts to it, but I am sure I will be impressed.

[3stagevtec 2]

some simple ported enclosures.. i'm looking for a 152 for the next show..

Very nice. Any vids? Also whats the specs on the box?

[3stagevtec 2]

thoe boxes were made for my previous Audiopipe subs, so they are not really a match for the DCs..

they are 5 cubic feet each currently tuned around 46Hz! 3 - 5 layers of fiberglass & resin on the inside and a coat of resin on the outside to prevent the mdf from absorbing water.. double 3/4" mdf baffle.

i have to bring that tuning down to about 40Hz so it would better work in my vehicle.. when i lower the tuning, then i'll make some vids..

wow rene ... i have high expectations , cus i know you know your stuff... will you be ready for the show in may?

[3stagevtec 2]

for sure! i really want to see a 152 from them!

[3stagevtec 2]

i lowered the tuning freq to about 40Hz (net volume dropped to 4.1cu.ft) and just hit a 151.6 on the Audio Control meter this evening..

i believe another 0.5dB is possible with these boxes..

question, what's the best score you guys have seen made with around ~3200Wrms.. my personal goal is 152dB but i not sure if that is high or low for my power..

[turn it up 1]

I did 152.2 with 2.2k and four 12inch jl aduio w3before

And 155 with 4.4 k with four of these 15 lv4.

So i'd say your score is every good

[3stagevtec 2]

you scores are very impressive as well!

152.2 with 4 W3's on only 2200W.. nice!

[turn it up 1]

Any more work seen

[3stagevtec 2]

boxes are 4.1cu.ft each tuned around 35Hz..

power comes from a pair of Sundown SAZ1500D amps at 0.5ohms each..

My front stage is a pretty quiet pair of CDT components, they get drowned out quite easily...
