well its not my argument but if you want to talk about electrical parameters shift and plotting actual motor strength "bl curve" yet with the actual the input signal and how damping affects "actual" motor strength not only via compression but also electrical parameters shifts and how that affects not only amplitude but frequency i'm all for it. "big boy"How's the big picture out of context?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif Acoustic energy is way different than energy contained in the input electrical signal, and they are both different than the energy requirements needed to recreate a dynamic or sinusoidal signal using a subwoofer. You all need to get your energy and power ducks in a row.//content.invisioncic.com/y282845/emoticons/toast.gif.bc0657bf54b9ee653b6438524461341e.gif
oh and in what context are you referring to that "acoustical energy is very different from an electrical signal"? because that's not totally true. depending on what we are talking about. yes they are measured differenty but the fundamental physics behind operation is fairly similar.well its not my argument but if you want to talk about electrical parameters shift and plotting actual motor strength "bl curve" yet with the actual the input signal and how damping affects "actual" motor strength not only via compression but also electrical parameters shifts and how that affects not only amplitude but frequency i'm all for it.

I like your style.I'll pay in silver, crypto, or cash, your pick.
We can get into deeper technical discussion if you want, but unfortunately I'm less froggy today to post more technical discussion in which >99% of people could a damn[ about.

I do think a lot of it is miscommunication between posters. Also reading everything at 3 AM; I may have gotten my panties in a wad for no good reason. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I just wanted to make certain that people understood that yes power draw is different depending on signal and to give them some of the basics behind why that may be the case. People can take the information or leave it. I feel like I did my civic duty for the night.//content.invisioncic.com/y282845/emoticons/fro.gif.c695f1f814b01c4ad99fe7f8cccadd29.gifI like your style.
That said, you have wildly shifted the goalposts here. I have already posted (in this thread) picture of an impedance curve of my subs in the box and also the circuit which represents a woofer in a ported box.
The only point is that there is nothing true about "longer wavelengths take more power". In fact I have posted an impedance plot showing that my box at least will draw less power below 43hz when compared to 43hz. In fact it shows that the amp will not see the same impedance at any more than 4 specific frequencies but we cannot make any generalizations at all besides saying that at tuning your amp will make the most power regardless of the tuning frequency.
You could also make the case that if you want to play extended test tones you'll consume more power over time than more dynamic program material, but that should have been obvious enough to not even warrant discussion and it has to relevance to the topic of the thread since you can levitate hair with enough air particle velocity and turbulence regardless of the length of the tone.
he was referencing that in fact exist other variables but he was trying to explain that playing a 30hz tone and 60 hz tone from a physics standpoint requires the same amount of energy.We can get into deeper technical discussion if you want, but unfortunately I'm less froggy today to post more technical discussion in which >99% of people could a damn[ about.

My point was they are each discreet entities in the chain of getting a signal to your ears. For the sake of argument assume I'm right, even though the energy of the electrical signal coming out of the HU/DSP is approximately equal for 30 Hz and 60Hz (Thanks Water Bear for your input here!) that does not mean the mechanical energy output at the subwoofer system is equal between the two notes. Same for comparison at the speaker outputs at the amp. Yes, they are related, but they are each different values that do not have a 1:1 relation.
If I'm incorrect it should be easy to prove and even losing the bet it would be a cheaper lesson than many other lessons I've had in my life.
in rare form? meaning you was ******* sauced. ahahahaWe can get into deeper technical discussion if you want, but unfortunately I'm less froggy today to post more technical discussion in which >99% of people could a damn[ about.

He was asking what was needed to produce a hair trick not a box design.You are moving the goalposts yet again.
The only topic of debate here is whether or not the wavelength changes the RMS power of sine waves of the same amplitude. That was the original fallacy I attempted to correct.
Also I don't think OP is coming back because the answer he was fishing for was for someone to give him a box design that would let him levitate things in his windows with a single 18 on 2000W.
528 Hz's post.You are moving the goalposts yet again.

If there is moving of the goal posts that would be you unless you are saying he was not discussing the amp's current draw.Ohm's law says P=IE frequency is not part of the equation.

You and I both know the answer to that question and that that answer isn't what he was hoping to hear.He was asking what was needed to produce a hair trick not a box design.

It looks to me like that link is dealing with a signal riding a carrier wave in regards to communications (radio broadcast or possibly even primitive phone modem type applications). That doesn't seem to have anything to do with reproducing bass notes or music. Did you open that link?528 Hz's post.
"Higher frequencies have a higher current draw."

I didn't see a link by 528Hz. If you are talking about water bears, I did open it and glance at it. If I recall, it was geared towards electrical signal analysis, but it did gloss over some fundamentals.You and I both know the answer to that question and that that answer isn't what he was hoping to hear.
