Bronze Member Username: Moey_gSydneyAustralia Post Number: 99 Registered: Oct-06 | Very true. Speakers dont hit the low frequencies. Much easier to get that many DBs on speakers than on subs. |

Gold Member Username: Matt12490California USA Post Number: 2533 Registered: May-05 | You are crazy. It is way harder to hit 160dbs with speakers than 160 with subs. SPL stands for Sound Pressure Level and subs put out a lot of pressure because they play low frequencies (~25-70hz). On the other hand, any kind of speaker (mid range, subs, tweeter, etc.) 500hz will not have much pressure at all. If it was easier to hit high numbers with speakers such as 6x9s SPL contests would be filled with them. |

Gold Member Username: JohnfiacA-ToWn, 9515 thumpin... What u bumpin? Post Number: 3330 Registered: Mar-06 | ^u have to save target and open if using winamp... atleast i did... Also how can anyone say that hit 160db? I skimmed threew but i didnt see a meter, i seen sparks... ect. Blowing up speakers making them pop would make a pretty loud noise for a short time which could have been why it got such a high score.... throw 50K to a few subs that cant handle it and youll get a similiar effect,,, i think you all fell for some kid making up bs to say he hit 160+  |

Silver Member Username: ZacdavisBeloit, Wi Post Number: 596 Registered: Dec-03 | ReArrangeYaMind, You talk as though you know what your talking about, even go as far to tell someone their crazy. But truth is your the one who has been misinformed. It is quite easy to post HUGE spl scores with small woofers. The catch is, and this was already mentioned in this thread, you must use higher freqencies. One reason you dont see alot of competitors using smaller speakers is mainly due to the limitations most organizations have on frequency. The limit is 20hz to 80hz. The smaller speakers peak at frequecies higher than that. Although Dom and a few others have had exceptional results with smaller speakers while keeping their note legal. (hint, rule states must use the cd provided but says nothing about having to use the test tones, ok hell heres another hint, lol sine sweep:D ) Dom held a few world records, one of which was in his Caddy that housed a few dozen 5.1/4's, it did 170's. ;)   |

Silver Member Username: ZacdavisBeloit, Wi Post Number: 597 Registered: Dec-03 | Lol, its all good ReArrangeYaMind, Yeah those pics are from a few years ago when we were at the USACi world finals in Kansas. If I remember correctly he had 72 Memphis 1000D's on 16 volts running those little suckers. He's the same guy who builds alternators for alot of competitors, Dom's last names Iraggi. There were a few guys using 6 1/2's and 8's for port wars and getting mid 170's outta just one speaker, but again that's just port wars lol. But like you said, you have to move enough air to put up huge numbers in most situations, and a couple tiny speakers in a huge environment just won't do it. And Dominic's car is no exception, yes they are only 5 1/4's. But, collectively, there's no less cone area than (and I havent done the math) but close to 5 or 6 18's? Anyways you get my drift. I think the point you were making earlier was that in a vehicle, your never going to see high 160's out of just a couple 6x9's, and of course you're correct. That rings true for many apps. Typically, the amount of diaphram size/excursion versus the area of the environment being compressed would correlate with your score. Wow, that wasnt worded very well. ( and of course theres many other factors, motor force, frequency, and bla bla bla but...) Example, 2 18" subs in a Honda hatchback versus 2 18" subs in a school bus. Yep, theres less airspace in the Honda making it easier to put up higher spl numbers than the bus's. Theres a few of us playin around, tweakin n tuning, and finding some sweet spots that fair well with minimal set-ups. A great example of this would be Justin Whitty's newest crx project that he competes with. He runs Db Drag and does a 156 legal on the dash in a street A set up with only 1 12, yes, 1 12. Alot has do with woofer placement. In my rex, if i slide my box back as little as 4 inches I lose a full 3 decibals. Some competition vehicles are loud due to mic manipulation and nothing else. Have you heard a street vehicle sounds like it would destroy a certain comp vehicle, or at least you know it "sounds" louder, shake the ground more, yet on the mic, they suck. Take my buddy for an example. He has 6 18" subs in a tahoe with 15k watts, shakes the earth like Godzilla, then you take this little crx with only a pair of 12's and even though it isnt as loud and isnt moving nearly as much air...the score is still higher on the meter. Why?, because the wave is compressing in just the right spot. Mic placement, frequency, time alignment, phasing, all factors that can help a car put up a score higher than a car thats actually louder. didnt proofread guys, if somethin didnt make sense then, it probably didnt make sense lol.... Anywho, cool thread....   |
