Love the floormat. I grew up in the Burgh. The rig looks pretty good also.

I would expect that maintaining similar wire lengths would be more about maintaining similar resistance than anything to do with signal delay (which is not expected to be an issue for the reasons described above).

resistance = resistivity × length / area

Therefore if you have one wire which is twice as long as the other, the wire will be twice as resistant to the flow of current. Depending on the gauge of the wires and the lengths this could end up being non-trivial.

In theory, yes, but do you really think the differences are audible in the lengths involved here?

This would be a damning factor for my theoretical discussion of a 200,000' long wire needed to be to result in a perceptible time delay, however, the OP has a 100' spool of 12 AWG wire (pretty sure I do remember that correctly).

Using the link that @one more time posted, there would be 0.16 Ohms added resistance if the entire 100 feet was used for one speaker.

But thanks for mentioning it! It is always a good idea to dot the "i's" and cross the "t's"!

So after getting everything hooked up and doing the Auddysey speaker test, one of the SVS Ultras was real low, distorted, hard to discern the beep noise while the other was loud and vibrant. Far as playing through cable, the “bad” speaker didn’t play at all. I tried switching sides, same thing, good speaker played, other did not. Man, so let down.

Get ahold of SVS, they’ll help troubleshoot. I had a small issue with one of my PB-2000s when I first got them and they found the amp was bad. They sent me a new one to swap in.

 

[KEW]

Yeah, let them know. They'll probably get you to do a couple of tests to verify the type of damage to the speaker, but they will take good care of you!

Bummer none-the-less!

Actually bought from Worldwide Stereo. Will they do the same?

Speakers still came included with five year warranty according to Eirkdwide Stereo.

Do you also get the 45 day free trial?
Was the price less? (just curious why you bought from them instead of SVS direct)
I don't know what the arrangement is, but I am certain that SVS would be the people to provide warranty support.
I would call SVS first and ask them if you need to work with WW Stereo (or check you warranty information - it probably says to contact SVS for claims - although since this is brand new WW Stereo may offer full replacement). My reasoning is because I know the person who answers the phone at SVS will know what they are doing (and are likely to help troubleshoot it out of their own curiosity).
I don't know about WW Stereo's CS, but SVS is a very high bar!
Like I said WW Stereo might offer a full replacement for a DOA.

One thing you might be thinking about is how handy are you?
I think you can reasonably get a replacement speaker sent, if you choose.
However, I would rather open the speaker up and replace a driver or crossover than go to the trouble of returning the whole speaker.
Once they troubleshoot it (with your help), they will be able to describe the process required to swap the defective component (or it may be a wire came loose in shipping)! If you are not comfortable with the task, let them know.

Let us know how it works out, but SVS is a company that recognizes how important customer service is, so they'll work it out!

Thanks for the message. These were on Ebay through Worldwide Stereo and sold as a set that was a return from a customer with minor cosmetic damage. They took $600 off and said it still has the full five year warranty on it. Everything in the box was still in its original packaging sans the speaker themselves. I've contacted them through E-mail and will contact SVS this afternoon as well to see what I can get done. I am not sure I'd know much about replacing the guts of the speakers at this point, but I'll have them instruct me on what they think is best. Just frustrated, man, was really looking forward to this.

That's messed up! I hope the first owner didn't buy em, blow em, and return em! And even so, any Web Store worth a damn should always inspect and test expensive electronics when they are returned!

Here's what they said...

Ok maybe it's something as simple as an internal wire slipping loose. Do you know someone who can come by and would know what they're looking at inside the speaker?

 

[highfigh]

LOL. I read something (maybe on this site?) about a US Admiral that used to hand out nano-seconds at conferences. It was a length of wire in the 1-3 foot range.

Very clever. So, no, identicle length speaker wires not needed. Just keep the lengths within several feet or so.

I bet it was Rear Admiral Grace Hopper. I saw her on TV and it was very interesting.

Look at it this way:
Do you have a light switch in your house that controls more than one light fixture? Most commonly is a two bay garage or basement. The fixtures are often an easy 10 feet apart. When you flip the switch, is there a delay between them? Trick question! Of course there is! The electricity (normally) has to go farther for one of the fixtures! But can you detect the delay? Assuming your wiring is not partially eaten by rats, you should not be able to detect any delay because the delay is minute compared to our ability to detect changes. IOW, this delay is so small as to be inconsequential to humans (and, I would presume, all biological organisms).

IIRC, we detect visual stimuli at a rate of around 0.02 seconds (don't take that to the bank).

My memory is probably wrong about the 0.02 seconds, but if it were right it would take 200,000 feet of wire before we would detect a difference. However, as long as you allow me plus or minus three magnitudes on the 0.02 seconds, we are still well below the threshold (and given that type of tolerance/allowance, you can take it to the bank)!

You're probably pretty close- I haven't seen incandescent lights on 50Hz, but that's what .02 seconds corresponds to and IIRC, that's the reason the US uses 60Hz.

Hopper spoke at the university I attended in the 70s; I was there. She didn't hand out nanosecond-sized wires, but she did hold one up. I always hated COBOL, which was her claim to fame, and thought it was a pox on computer science and programming. Fortunately her talk was a lot better than the language she worked on.

I run into the equal length cables myth more than any other, but mostly not over latency; mostly over the differing impedance and capacitance factors in speaker cables. For any well-designed cable of appropriate gauge (for the longer leg) where the length differences are 10x or less, those factors are irrelevant too.

Agree. I'd go a step further and say that outside of exceptionally rare circumstances, negligible capacitance differences are irrelevant.

WRT well designed cables, they really only need to be:

1. 99% Copper (OFC, silver not necessary);
2. Reasonably insulated -- exotic dielectrics not necessary:
3. Of proper gauge, relative to length: and
4. Well terminated (bare, crimped or soldered, but exotic terminating materials not necessary).

New message from: world_wide_stereo_outlet (9,070)
Yes, the boxes were beat up to begin with. The unit went through several steps of QC with no issues. It sounds like maybe wires came loose during transit due to vibration. Focus on the sound with the receiver. Can you tell which speaker part isnt working? The top woofer, middle tweeter, or lower woofer? ••••I’m a super newbie. How do I test these different parts of the speaker or see if a wire came loose??

The TV should connect to the receiver. How is that hooked up?

I never worked with COBOL, just Interactive Fortran and even with that, not for long. I commuted to school and could never get into the computer lab- the only time it was slow was usually between 2AM to 6AM and that was not gonna happen.

I went to CEDIA in 2005 and was scheduled to attend the 'Audio Setup and Calibration' seminar- total waste of time, since A) I had already been working in audio for a couple of decades and B) the guy spent most of the time telling us how cool he and his company were. He described how all of the speaker cables should be the same length and one of the guys I worked with asked "So, we're supposed to coil up the excess and hide it in the walls?". "Yes", was the answer.

If an amplifier can't handle the different lengths of cable, is it really a good candidate for the project?
