Power and Peak Frequency Change

[fecupe2001]

That´s always a HUGE advantage, i dunno why people (not talking about you) think that buying a TL it´s just for comps or something like that, man , once i bought my TL i had the first huge tool to get me really loud, after that, i bought a clamp meter and got even louder, someone stole it from me though

As little as 1" of enclosure movement changes everything in my car! Yes swapping amps can affect everything as stated before each amp has its preferred freq to make power and it is highly doubtful you will get the amps setting the same for both crossover points and gain settings.

Interesting topic since I've theoretically tripled my power from the last time I metered. Will have to set up the same way I did b4 and try again.

ok let me see if i can explain this right yes power can change you freq by alot if your going from lil power to big power now the resone when you have low power it takes more power to burb at 35 hz then at 55 hz cause the sub does not have to move as much at 55hz so on lil power the higher freq will be your peak but on big power you peak should be a lot closer to your tunning freq being that not relying on efficiency

now when you already have big power and going bigger then you freq should stay the same or be differnt by a few hz

ive also seen "peaky" boxes that play just one freq really loud and other freqs play ike meh become not peaky and play everything really well with added power also these peaky boxes went from a peak of 48hz to a peak of 36hz with added power just vaildating my low power statment

I found out best most accurate way to find peak freq is to burp at half volume or less in the mid 130db range. Start off at 32hz and without reving the engine or touching any knobs play the freq for 2-3sec then switch to next one and do the same you need a tl of course and set it a peak hold and u will see where it peaks and were it drops

Dammit, now you guys got me itchin' for some TL time. Last I was in I peaked at 41Hz.

that works some times but then my low power thing comes into play i have seen it on many many differnt builds where half power had a peak at one freq and full power had a differnt peak and that was just cause it took less power at 50 hz to get the sub playing loud then it did at 35 hz i test at 3/4 volume now this is not a rule because ive also seen the way dc98hoe does work as well
