I thought the only way to make a street system more streetable would be a sign sweep over 40-(?) hzs. taking the average spl reading. Isn't most street boxes designed for a range this would limit ports. high peaking spl only boxes limit amps a little. and make for better sound spl boxes that are more like the normal street boxes.
personally i am not in favor but it seems logical
maybe new box designs will come from it.( port-horn highbreed)

I think sweeps are a good idea, if nothing else I think the spectaytors will enjoy watching the mic climb instead of the instant burb. Sounds very "streetable" to me

I use sweeps as of late. At a show i realized if i did a sweep, my score actually went up a tad bit, then using my tested res freq so thats what ive been using, and plus, i do enjoy sweeps alot, but i prefer from about 30-65

The only problem that I see with using a sweep is the way that the new metering system measures. With the older type meter, it would pick up on the peak note, but with the averaging in the new system, it wouldn't take the peak note's full score. Know what I am getting at?

What I think Johnny is saying is that with the old system it took samples as a measurement and recorded the peak number. With the new termlab it still takes samples but instead of taking the peak, it averages a few samples over a very short period of time and give you the score. Now I could be very wrong in this but its what i think he was getting at

okay that makes sense but why would that change the results. I longer play time of like ten seconds ma be needed but it should still work not every Hzs has to be metered it is just to get the more broad range out of the boxes.
Everyone will still have to find a good comp between the range and the peak of the box.

Its not about YOUR car, it's about whats good for db drag as a whole.

I see that on the new mics I have the same score running sweeps or just playing my peak freq. I don't understand the comments about the averaging the score I see a peak on the new mics the same as on the old.

i like the burp with three second break. I pick 40 to be easier on equipment and a good comp between cars. My car peakes about mid fifty firing forward but my best spl is at 58Hzs.
and personally i don't want this but it seems the best way to make street more streetable.

Your score probably went up because your tested note is not the correct note. Either that or you are clipping your amps during a burp.
Find your note doing burps again (this time try everything from 20-80hz) Then let the electrical system rest and hit it. Let the electrical system rest again and try rolling up to your volume from zero. Garunteed to be louder than a sweep if you are in street...

The computer program will actually average the spl over the entire 30seconds is what I thinkg the origional poster was getting at. With the current street classes as they are, I'm not sure we want to do that.... even my 9915s cannot handle the power for very long that I'm putting on them. And my power is just average right now....
Johnny's point was that the scores will be UNIVERSALLY down EVEN more! The brutality of this mic has driven quite a few people away from db drag.
At the NOPI 3x in ATL, I was talking to a dude with 2 sealed 15s and 1kw. I told him to expect nothing more than a 143 when he asked what I thought he'd hit. He did expect more, especially after I qualified with a 149.7.
He went in and tagged a 142.1, and he looked like he was going to cry. I tried to explain to him that this is the HARDEST mic in the world, but he didn't listen. He didn't qualify and he didn't come back the next day....I'm worried the new mic may be doing this to a lot of people right now, do we want to lower the score for them even more?
Steve
PS - I LOVE the new mic for it's consistancy, it just slaughters the newb's expectations big time to the point of demoralizing them...

Just pointing something out, but if we do a sweep through most of the bass region like say 45-60Hz, then those with CRX boxes will still be dominate. A very small ported box, tuned to the mid 40s will still have a fairly flat response over the window of 45-60 Hz. It would only make the almighty small CRX box even more dominant.

It is usually agreed that music has notes lower than 40 hz, and a significant number of songs have tones below 35, but very few have below 30, so logically, 30 hz should be the limit. Besides, if your subs cant take the 4-5000 watts max with amps on a single battery for 10 seconds then.
I think my idea would be nice, you get the best of both worlds, SPL, and music compatability.
If you start at the burp freq and go lower, it can't really do anything louder than the initial burp. So if a CRX burps at 65 or whatever, it will go from 65-35 hz, in 10 seconds. If the subs fry, you need a better box.

so what you're saying is you want a rule where you can burp from 35hz to.... 35hz in your car.... yeah.. back to benifiting dB Drag again..

i'm on dial-up... probably about the slowest connection to dial-up there is too... living in the middle of no where is crap. No one has ever complained so I've never took it down... I've seen plenty of signature pictures on this forum as big or bigger than mine (in physical size and byte size)
