Speaker Cable

[traderbam]

But SJ was talking about buying new cable - so he can buy the appropriate lengths - no joints!

Too much disguise on that one, eh?

 

[Galu]

Obviously! I'm in real danger of taking this discussion seriously!

 

[scottjoplin]

If the discussion is about joints I don't think it should be taken seriously, contacts, possibly but a good strong joint is not going to kill you.

 

[traderbam]

The government of Canada agrees with you.

 

[AllenB]

If your cable has a joint it is going to distort the image and produce time delays.

 

[Galu]

No more than scottjoplin's WAWs will!

Only joking SJ - I hope!

 

[TheGimp]

I fail to see how a splice in a cable (when properly done) will have any impact on signal propagation in the audio band.

Up in the hundreds of KHz maybe, but not sub 40KHz.

 

[DF96]

Once you start soldering an extra length on you make electrical discontinuities at the joints that cause reflections. You don't really want to go there.

It is never clear on this forum when people are serious and when they are joking. Of course, we don't know whether SJ has speakers which go up to UHF, where cable joints might become a problem.

 

[traderbam]

I would like to make an official statement on this matter.

My post #97 was intended as a ****-take of Galu's post #94 where I deliberately mis-interpret his wording concerning adding length to one of the replacement cables. Meant to be funny because a new cable can be cut to the right length in the first place.

In my defence, I would like to point out that almost everything I have posted in this thread is a load of crap. Be warned: I intend to continue along these lines. There are some who are now thinking that everything I have posted in this entire forum is crap but I still claim that my posts in this thread are significantly more dung-heavy by comparison.

 

[scottjoplin]

I blame whoever moved it from "Parts" to "The Lounge", it appeared to be going ok before that.

traderbam, am I to assume that your cable recommendations were a load of tosh or were they the exception?

I object to that kind of language - if anyone is posting crap around here, it is me!

On the crap scale, you are merely a number two!

Haven't you got some homework to do?

 

[Galu]

No - I've been expelled for vandalising the school toilets!

Would I lead you astray, Matt?
You already rejected my flat cable suggestion. Have you decided not to lay camouflaged, non-trip, flat but curvable cables across your cork floor? What are your requirements for a perimeter cable?

 

[scottjoplin]

Whatever. An update, I'm not buying any more wire at present, I've ordered some "D-line quadrant trunking" to run round the skirting and intend to use more of the 1.5 sq mm brown mains conduit wire I bought cheap off eBay some time ago. I'll be running 4 wires for woofers and wideband, would it be best to twist them into 2 pairs or just leave them loose and separate? I can't imagine it would make much difference either way. I know ideally they should be the same length left and right, but again, can't think I'd notice any difference and it would mean a stupidly long length coiled up (or sheep thingied) on the right

Edit: wrote and posted before I read your reply...

 

[Galu]

Technically, it will make no difference if the two runs are not equal - unless you're taking one of the runs to Scotland and back!

However, not making them equal will nag away at you and induce eternal worry, doubt and distraction!

There would be a lot of twisting involved, in all probability, to no good purpose in your situation.

 

[Galu]

P.S. And you know you shouldn't coil the excess wire due to the inductance that would create!

 

[scottjoplin]

Not quite true, it will effect damping, but I take your point

However, not making them equal will nag away at you and induce eternal worry, doubt and distraction!

Believe me, it won't, I could always match the resistance?

Agreed

 

[Galu]

Re the unequal lengths - I was thinking in terms of time delay - I've read a discussion on how insignificant this is in a domestic situation.

And the idea of adding a resistor to compensate for unequal lengths just doesn't sit for me - again for nagging doubt reasons!

 

[scottjoplin]

Oh, time delay, haha, yeah, I've come across that in forums. I know what you mean about adding a resistor, but theoretically that should match the damping....
