Ah, I just figured out why...that's my 535 kcmil twisting fixture. The plywood is 7 inches thick, the sheetrock screws are 12 inches long with three inch heads...and the motor is a 3 phase 200 hp beast..
I'll be sure to reduce the naked jpegs on my hard drive prior to uploading again..sorry...
Sorry, I'm rarely clear...
When we need a specific twisted pair or tri, we normally just unspool the amount needed plus abut 5%, tie one end to a doorknob or some equally technical attach point, and chuck an eyebolt or coathanger into a hand drill. Attach the wires to the drill, then spin it...
It is not difficult to make a twisted triad which maintans a constant impedance on all three wire combinations. For example, 100 ohms + to - and 100 ohms each to "pin 1". All one has to do is maintain insulation contact between all wires. Twisting with a drill will not do that, as the unwrap...
I have had two different scenario's for blown tweeters.
1. Total power: vc burnout as a result of beating the living daylights outta the system. Autopsy of the tweeter shows a dark brown mess, burned epoxy and such. I have one such example I use as part of my tours...a combination of...
That's also happened to me as well. In my case, the moderator informed me (after I asked), that the mods did not have the tools to cut specific posts out and re-establish a tree link. Offensive posts prior to mine were culled, I was collateral damage. The mod was a nice guy, on occasion we...
I've had timeouts applied, even though they were "unjustified"..:confused:
One forum owner had my privileges modified so that I could no longer post schematics or diagrams in support of my arguments. That was a weird one. I had provided evidence in support of biwiring, and that was not...
Interesting. I AM one of the measurement crowd..:confused:
You only need to match two loudspeakers, the center one can stand alone. It's not a case of frequency response or phase amplitude with the center one.
As to your comment regarding speaker differences swamping the cable effect...
Oh, forgot to mention this.
If one cable is found to delay some of the spectral content with respect to another, a typical argument is along the lines of ""yes, but since both cables have been swapped out, the delays are symmetrical therefore the change is net zero.""
It does sound like a...
I've seen that stuff before. Simulations and measurements which say "too small to be audible".
Unfortunately, our ears discern things the measurement apparatus has not been setup to find.
As an example, at 1khz we can discern interchannel differences of roughly 2 uSec. This discernment...
I do not understand why they need to measure long spools of wire to determine the per foot parameters.
It is easy enough to measure a 6 foot piece to get the capacitance and inductance. Yes, they do need to know how to zero the meter, but that's pretty trivial if one reads the manual...
Shame. Although, comparison of a 25 ohm Z #17awg vs a 120-150 ohm Z #17awg is not very interesting..
I had to run a 4 ohm cat5e cable to do a test here, I needed 10 uSec risetimes of 40 volts into a 4 ohm load, so ran 6 cat5e cables in parallel, solids together and stripes together. It...
