melonhead Posted March 31, 2010 Report Share Posted March 31, 2010 (edited) ^There you go right there. Imagine it being 10 oclock and the little hand on the clock pointing to the 10. Turn the nob on the amp until it looks like the little hand pointing to the 10 on the clock. Edited March 31, 2010 by regal1382 Quote Link to comment Share on other sites More sharing options...

chewie Posted March 31, 2010 Report Share Posted March 31, 2010 (edited) even better. set your amp with a multimeter at 50 hz.. should be somewhere around 50 volts ac. for 2500rms@1ohm iirc and then play a 80 hz tone with the volt meter still connected and turn it to the left until the voltage starts to drop. simple and accurate Edited March 31, 2010 by chewie Quote 91 dodge colt gt.. 4 custom t600 15s audioque 3500d.1 tuned to 25 hz... stay tuned. blazer stroker 15 brutus bxi2006d terrible voltage drop 145.4@38HZ...

kweezinarts Posted March 31, 2010 Report Share Posted March 31, 2010 (edited) 250hz-35hz=215hz/2=107.5hz is 12:00 so a little bit toward 11:00, maybe like 11:17 edit: i might be wrong heh...

R_Mac_1 Posted March 31, 2010 Report Share Posted March 31, 2010 (edited) play an 80hz tone through the subs start at the lowest setting 35hz and turn it up once it hits 80hz the subs will no longer play Not quite. Start at around 12 or 1 and then play a 80hz tone and back it down until you start to hear it get quieter. The crossover is not a brick wall. Even with the low pass set on 8O hz you'll still hear stuff above that. It'll just get quieter. How fast depends on the crossover slope.

HHR Ed Posted March 31, 2010 Report Share Posted March 31, 2010 (edited) Its on a slope, so it doesnt have to be exact. Could be 12 dB per octave or 24db. That means, even if its set to 75hz, or 85hz, you will still be letting some signal over and under through. If its set to 80hz, an octave up is 160, so 12db/octave will let a signal of 12b lower than full through at 160, and progressively higher the closer you get to 80.

nCOMP1337 Posted March 31, 2010 Report Share Posted March 31, 2010 (edited) i would think it would be a bit closer to 9 something take the average of 35 and 250 and its 142.5 , which would be pretty close to 12 o clock, notice the numbers do not meet at 6 o clock though, so i would take 285 divide by 11 and you get 25.9 , round to 26, so basically each hour is equal to 26 Hz, which puts 5 Hz in between 6 and 7, which would make 7 o clock about 50 , 8 would be 75 , 9 would be 100 , 10 would be 125 and 12 would be about 150, now this is pretty close to my earlier suggestion that 12 is about 142 since its the average of 35 and 250, but taking into account that n umbers dont go all down to 6 and it ends about 5 instead of its original starting point id say this is close so every minute is equal roughly to 5 Hz, but we will say 4 Hz since 250 doesnt complete a circle, so 80 Hz would be equal to 20 minutes or 4 total Hour skips (from 35 Hz roughly between 6-7 , to 80 Hz which is around 9) 35 is a 6.5 , so we will say 3 minutes to 7 , makes it 47 since i said each 1 minute notch equal roughly 4 Hz, so another 5 to 8 o clock makes 67 , then we have 13 left to get to 80, so 12 is another 3 notches so that puts it at 8:43 roughly, making the total Hz at 79, so just in between 8:43 and 8:44 should be 80Hz 7 = 47 8 = 67 8.5 = 77 8.66 = 80 Hz here is an image with the dial actually at the point im talking about i wont say its exact, but its gotta be close EDIT: damn, every number 80 (eighty) is damn emoticon, LOL Edited March 31, 2010 by kynto Quote Link to comment Share on other sites More sharing options...
