136.6db Avg with a 137.8 Peak @ soundoff

[JamminWagon]

Local stereo shop had a USACI sanctioned sound off this afternoon. Streetbeat 1 class. I need to learn to read rules, MUSIC to be played not tones. I had to scramble through my cd/DVDs to find something. It reading is an average during a 30sec run. Bassically need music with bass through the whole passage. I found 1 track. Was 3rd til a last minute entry took first. Thats my only complaint about this. He knew he could hit 139+ and waited to see what everyone else did before plopping down the $20 to compete. They need to stick with the original plan of Registration from 9-11, guess they are just money grubbers and wanted the 10 or so people who showed up and hour before the end and jump in. Oh well, the numbers were

1)139.1
2)138.8
3)138.6
4)136.6
5)131.2

Not bad for 16.6db over the 120db threshold of pain. (Every 3db requires X2 power, every 10db is audible X2)

103 dB Jet flyover at 100 feet
105 dB Snowmobile
110 dB Jackhammer, power saw, symphony orchestra
120 dB Thunderclap, discotheque/boom box
110-125 dB Stereo
110-140 dB Rock concerts
130 dB Jet takeoff, shotgun firing
145 dB Boom cars

Not sure if I am going to find some better music or just hang it up here. They used a ProTerm meter in a lil cage thingy and placed at the passenger foot area.

not bad, what were you using?

[northeastern08]

Nice numbers semihemi

I have to get around to checking out mine...have my meter in my garage somewhere, I just have to find it

(BTW: His equipment is on the bottom of his sig, if thats what you're lookin for)

Cool. My brother has a handheld db reader which has 126 db max on it, which im not sure how accurate it is +- a few maybe, but i can hit 126 db on the reader easily withe it on the center console facing towards the front of the car with my two JL 12W3v2's powered by a JL e1800 Amp in a sealed box. Would be cool to see what db's i can reach with them.

nice nubas i was doin 152.1 with my old setup.

I jsut need to step up to the TREO 12"SSx and the alpine M1005 haahh, that would put me in the 138 range easy. BUt i have gotten bored with it all lately. Seriously thinking of taking the sub out and run around town with just the 75X4 and the dash speakers.

[grinner]

can I talk ya into a 12" T1 sub in a custom fiberglass box instead???



I'm keeping the amps. Just puttin em under the cargo tray and going with two 10s in the cubbies.

HOLY ****in **** colossus3200. What the HELL kind of set up is that? I love it, I only got a 10" square Kicker w/ a RF amp. It was hooked up by my local audio place. But my main concern was hiding everything. You can look in my back end and not see a single thing, unless you know what the back end is supposed to look like. Once again, HOLY ****in ****!

[colossus3200]

again that what i used to have. if u wanna se pics of what i have now u can check it out here old sub setup in my mag but what i did have is the four 12" hifonics atlas and the hifonics colossus the amp u see below

[colossus3200]

by the way i used to love kicker till i started using these and i would never go back, check out what i used to have in the back seat of my saturn 2 15l7s and 2 kx1200.1s



and even a fiberglass rear deck with there logo lit up



oh yea and the sub i originally bought that amp for the 10in kicker solo x

[Duke]

Thanks man. I'm pretty sure I'm in love with the square sound now since my newest sub

I did a 137.1 (MECA style) with 1 Brahma 15 and 1580 watts RMS in a 2.75 cube enclosure.

Ok... not trying to be a chanker on the on the willy of joy here, but doesnt the ability of the human ear to hear details in music rapid fall off at 110-120dB? Thusly making what you hear to be just so much noise?
I am not really familar with hyper powered audio systems but if maximum loundness is the goal then why not use a compressed air horn type device?

Also are there any awards for purity, detail, and clarity of sound?

[Magnum-RT-AWD]

because in most comps. you have to be below 80Hz----and yes there are awrds for SQ(sound quality)----that is what I built my car for----headroom is a great thing in my books since music is do dynamic---5 speakers and alittle over 3500 watts RMS of pure SQ bliss!

Finally figured out why it didnt hit as hard as I thought it could. Friggin ALPINE and they way they do the input gain. Its all electronic, the numbers are from .1 to 8.0 (if i rememeber right) .1 is screaming while 8.0 is low. I normally keep it at 2.0 but decided to give a lil more umph and go to 4.0 or so I thought. I put it back to 2.0 and BIG diff, put it on 1.) and man BIG BIG dif. I will have to wait til May 21st now to see what the changes will do. Now just need to find a song with constant bass, thinking of Mariah Carey's Breakdown. Need something with slow, constant bass for 30 sec.
