Kyblack76 Posted May 1, 2014 Report Share Posted May 1, 2014 I have 2 settings. My music Set with a over lap due to the vari in music. I set at -7,5 with tone, say, when i burp... i re DD1 or tune at ZERO db. Tones, need no overlap. Most tones are recorded at odb. So, when i compete, my music, i run a full 62 clicks. When i burp, its 57 clicks clean, on a tone. just me edit - i also struggle higher. I can play 30hz all day.... 44hz, and voltage goes down, gear struggles. And im tuned at 35. ish... DOUBLE edit... why would noise, or distortion matter low, or high, unless it was more gear dependant.... or you could just eliminate THOSE freq's... That dont make sense to me. So, you cant clip/distort at say... 4k????? .. mmmmm im calling bs SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted May 1, 2014 Author Report Share Posted May 1, 2014 probably box rise. it was unloaded, in my case. edit: my voltage sags down low. up high (40+) im good, in reference to kylar Best Score to Date : 160.5 dB Outlaw (47Hz)[4 XM 15's & 2 Taramps Bass 12k's] BL : http://www.stevemeadedesigns.com/board/topic/147800-chevyboy95s-4-15s-7krms-wall-1533-db-on-half-power/YouTube: http://www.youtube.com/hitemwiththeflex/ Link to comment Share on other sites More sharing options...
DubNDodge Posted May 2, 2014 Report Share Posted May 2, 2014 tuned in for smart answer. I've been pondering this for awhile.

Kyblack76 Posted May 2, 2014 Report Share Posted May 2, 2014 I think, noise or clipping is where ever... its just that MORE damage is done, low........ I cool lower, and can play 28-35 more than i can plus ten.... IMHO clippiing wouldnt be ....say... under 32 or something. That sounds odd to me.....

Krakin Posted May 2, 2014 Report Share Posted May 2, 2014 I'll do some looking into my amplifier design books and see if I come up with a scientific answer as to what it may be. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . .

Krakin Posted May 2, 2014 Report Share Posted May 2, 2014 There are the slew rates of some amplifiers that are lower than others and will affect the output in the upper ranges of the frequency bandwidth. Quote: S l e w Frequency response and distortion figures of amplifiers are normally measured at 1 Watt. The maximum power of an amplifier is normally measured at 1kHz. At 20kHz most amplifiers can not deliver more than 1/4 of the power quoted at 1kHz as in the graph below. The limitation of power restriction of amplifiers above 10kHz is described as Slew. It is not possible for any electronic circuit or individual component, transistor, FET or mechanical switch to be able to turn on and off instantly at the speed of light. Slew is the highest speed an electronic circuit, transistor or FET can change from on or off. Volts / micro second is Slew rate. With an amplifier of + – 60V supply rail, the leading edge of a 20kHz sine wave would have to change from 0V to 60V in 1/80,000 of a second ( 12.5uS ). Therefore it has to have a slew rate of at least 0.2V / uS to reach 60 Volts in time. But if the amplifier output can only change at 0.1V / uS the maximum voltage it could reach is 30V which is half way and therefore 1/4 power. Many amplifiers that use power MOS-FETs have very high slew rates and are easily capable of delivering 20kHz at full power. But many amplifiers that use output transistors are restricted in being able to deliver full power at 20kHz. Slew can be intentionally applied in a driver circuit of an amplifier (dominant pole capacitor) to insure high frequency stability and freedom from internally generated parasitic oscillations. But there is another unique problem of slew that is caused by the internal limitation of one or both output transistors not being able to turn off as quickly as they can turn on. This problem causes a large quiescent current cross conduction through the output transistors that generates extreme heat. An amplifier with slew limited by output transistor cross conduction can be destroyed by high frequency oscillation caused by a reactive capacitive speaker load or Rf (radio frequency) getting to the input from an external source. http://lenardaudio.com/education/12_amps_3.html I'll continue to look into more once I get back from an errand.

Kyblack76 Posted May 2, 2014 Report Share Posted May 2, 2014 ^^^^ fucking DOOOOORK sooooo 28 hz dont clip any more that 30 IF this and that, with that and this...... other wise, people wouldnt RUN this or that..... meh.. Im gonna go hammer 29hz, for 3 minutes.... peace out SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...

ParDeus Posted May 2, 2014 Report Share Posted May 2, 2014 More area under the curve in a 25hz wave, as compared to a 40hz sine wave with less total area? Think of it like this- Waves in the ocean. 25hz is one big wave, 60ft wide, 100ft high. 50hz might have the same amplitude (hieght), but are much more narrow. Say 2 waves, 100ft high, but on 30ft wide. The bigger wave has more volume of water=more electrical draw on an amplifier=lowered input voltage=clipping. Now, I could be talking out of my ass, but that's how I picture it in my mind. Link to comment Share on other sites More sharing options...
MrSkippyJ Posted May 2, 2014 Report Share Posted May 2, 2014 When you did this, you were setting at max volume right? Do this: do the same test again, but do it at half volume, so that electrical supply isn't a factor. Bet you get different results probably box rise.He said it was unloaded. Impedance varies even while subs are not loaded, so it could still be an issue even if you take what the box does to impedance out of the equation.
