Diamond Member Username: BestmankindLos Angeles, CA USA Post Number: 20284 Registered: Oct-05 | well when i meter my car, what is do first is run a sweep at decent volume. then it shows what frequencies were the loudest. so lets say it was loudest at 50hz. then i get a 51hz, 50hz, 49hz, 48hz and let it rip. |

Its pretty cool. Me and my cousin use it with FL studio for making beats. Also you can burn a cd of whatever you make so that could help you when you need to narrow down the sweep. |

Gold Member Username: InsearchofbassPost Number: 8962 Registered: Jun-04 | it was either 52 hz or 54 hz and even though Dwight was tuned to 40 hz and Kangology 101 is tuned to 33 he will probably be close to Dwights frequency |

Post Number: 5786 Registered: Apr-06 | the best way to find your resonant frequency is to throw a 10 in a sealed box burp it at EACH frquency say from 30-70 and record what you hit at EACH freqency..... then take the same enclosure out of your car and put it in a big a field or open parking lot were there is nothing that can obstruct the sound waves....then put the TL literally inches away from the cone....meter it AGAIN at EACH frequency, record the number at EACH frequency....then take the two sets of numbers and subtract them so like 130 @ 30hz for the first one and 115 @ 30 hz for the second set of numbers gives a 15 db gain...so at which ever frequency you get the best gain is your resonant frequency...this is alot of work but it is the MOST ACCURATE way of find your vehicles TRUE RES. FREQ. ive done all this and its a painnnnn |
