Krakin Posted September 30, 2014 Report Posted September 30, 2014 My point was that there is no "downstream" in AC like there is in DC. If you throw in a resistor or a capacitor to form a filter it doesn't matter whether you put it before or after the terminals to the speaker. Edit: If you are just using the term in a way I'm not getting, then don't take my answer as a dick answer. 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 . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
_paralyzed_ Posted October 1, 2014 Report Posted October 1, 2014 No worries. I was wrong. Thank you for teaching us Wicks!
OrionStang Posted October 1, 2014 Report Posted October 1, 2014 Wicks, great explanation. But that scenario is at a single frequency, correct? So how would things react in a song with many transitions and frequencies? Would the variac have to adjust for each one? Or would you set up the variac at the frequency that shows the highest resistance? Sorry if its confusing LOL. I have these questions but don't know quite how to word it?

philrab Posted October 1, 2014 Report Posted October 1, 2014 Regarding frequencies, I thought the original intent was to use this for single frequency burps. 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

OrionStang Posted October 1, 2014 Report Posted October 1, 2014 Ok, and I am asking if the idea could be applied to music, not strictly tones. SMD Super Seller My Feedback Thread
STEvil Posted October 1, 2014 Report Posted October 1, 2014 Here's a dumb suggestion: If this can be utilized, can we create drivers with ultra-low (or maybe better to go high?) impedance to make proper use of this setup? MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

A variac is just a variable transformer and impedance matching transformers were/are used on music all the time. Assuming the variac can handle the low frequencies which I'm not sure on and might need some testing or research. Let me dig around and get one of my own impedance curves and I'll explain the different frequencies further....

SnowDrifter Posted October 1, 2014 Author Report Posted October 1, 2014 Original idea was for burps. However... I intend to test it on music too. Could be a very easy way to "wire down" for burps ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
