He can use the CAT5 cable, he just won't be able to use the other 2 pairs, and he'll have to make sure he's consistent with the way he wires them up to the jacks.
CAT-5 makes great speaker wire. A music/audiophile taught me about it a few years ago.....and it's true. Sound is much warmer than with "good" monster cable.
Cat-5 is shielded and twisted.....nice

G$, and lots of it.

Just a guess and its prolly wrong. I would imagine feedback of somesort.
Tried that once, but could never get the little crimp connectors to hold onto the wee little wires.
CAT5 is generally UTP or unshielded twisted pair. If you want shielded, look for CAT-5 STP or shielded twisted pair which costs a little more than standard UTP.
They make it more complicated than it needs to be.
You use two cables for each speaker, one for positive and one for negative.
Just strip the ends and apply whatever connection you want. Or just use the bare wire.
Regular cat5 is all you need. The twisting provides the shielding that's more than adequate for ht use. Much better than regular shielded speaker wire that costs 100 times as much.
Speaker wire doesn't need to be shielded. The power required to drive a speaker through speaker wire is several large orders of magnitude greater than the power required to create noise through line-level interconnects. The latter do sometimes need to be shielded, but that is a completely different issue.
Will using Cat5 as speaker wire hurt anything? No, unless the resistance is too high. You are dealing with small gauge wires, I think 28 or 30 ga each.
Btw, Cat5 is usually unshielded (in fact, it is often abbreviated as UTP, aka "unshielded twisted pair"), so this really isn't an issue in any case. The twisting ensures that any magnetic fields cancel themselves out, as well as negating capacitance, but this isn't an issue with any audible frequencies (i.e., it is an issue with the much, much higher spectra that computer networks use).
And Mariah simply needs a thin, even application of thermal grease.

You don't think tons of speaker wire laying over itself with half a dozen power cords doesn't need to be shielded? Not to mention the speakers and televisions themselves.
There's a reason that telephone companies use twisted pair.

I bought a cat5 cable made by Belkin. It is very stiff, retains bends, etc. It replaced a nice, flexible cat5 cable. Are some of these made with braided wire? Is there any way to know when buying? The flexible stuff is nice for cables you handle frequently.
"In fact, she should be locked up in a an ice-cold nut-house."
so ka! that's not the kind of house i'm thinking of though... bahahahahaha!

bahahahahaha!I don't see how CAT5 could be braided...unless it was REALLY fine wire. Those plugs are hard enough to crimp without adding braiding!
The patch cables (which these are) are made of braided wire. It is very, very fine wire! These are the best for connecting equipment because they are flexible. The stuff you get on 1000' rolls is solid 24 gauge wire. It's good for running in walls, etc.

Actually, most phone cords are not twisted-pair--certainly not the ones in my house. And, as mentioned, most Cat5 wire is not shielded; shielding is not the same as twisted-pair.
When you are talking about speaker wire, you need to realize that a typical speaker impedance is 8 ohms. A typical line-level impedance (such as the RCA jacks for a "CD input" or "Tape In" on the back of a receiver) is 10^12 or 10^15 ohms. This means that you need much, much more power to create noise through a speaker wire through inductance (which is how cables "bleed" sound to each other) than through interconnect cable.
To put it into perspective, holding an interconnect wire in your hand and rubbing your feet on carpet will create a crackling or humming sound, assuming the interconnect is hooked up to an amplifier. We've probably all experienced this. This is because the signal is amplified. Holding onto speaker wire will not accomplish the same thing, simply because your body is not going to discharge enough electrons to physically move the driver in the speaker to any detectable degree. (If your body did, you would be dead!)
When you talk about about shielded speakers and televisions, I think you are confusing static-field magnetic interference from the magnets in speakers, which is something entirely different.

omg, i couldn't agree more. JLH all the way!!
I have never seen a house's phone wiring not be twisted pair. The cord from the jack to the phone itself may not be, but that is because its a short run.
I know that most cat5 wiring is not shielded. Its the twisting of the wires that provides shielding to all forms of noise. The more twists per inch, the more resistance it provides. If it wasn't twisted it would act like an antenna. As far as I know everything from power lines, televisions, radios, and fluorescent lights can cause interference in both analog and digital transmissions. And since a speaker wire is carrying an analog transmission, I would say that it needs some type of protection.
If not please provide a link that shows different.
I'm a Sound Engineer by profession and I'm almost offended by this thread, no link, but twisting the cables provides shielding to NO forms of noise AT ALL, you're probably thinking of a balanced signal (where you have two opposite polarity copies of the same signal, so when you combine them, anything that doesn't cancel itself out is interference) speakers are not balnced, nor is any home audio system (maybe audiphile ones, but then again...) since they don't need to be, for such short runs unbal its even better, since you have one less noise-producing potentially-failing piece in the system.
Also, no speaker cables don't need to be shielded, yes stuff does cause interference, but the voltage in speaker cables is high enough no to worry about it, otherwise your speakers would make noise even with the amp off.
by the way if you had "tons of sepaker wire" that streched to say 40ft. then interference would be the least of your problems anyway, I don't even know the data for gauge 30 cable, but with gauge 18 cable a 40ft run to an 8 ohm load will have a power loss of 6.2%,(11.9% for an 80ft run, or a 4 ohm load) gauge 16 has 4%(7.7% for 80 or 4 ohms ) and gauge 14 has 2.5% (5.0% for...), by those numbers, a 40ft speaker run of gauge 30 ought to lose half the voltage.
Cat 5 as speaker cable, mhmm, thought I'de never see the day, it ought to work, just make sure you're working with a moderately low power system and short runs.
Edit: toned down a bit

She's such a dim bulb, though--but I guess you're not really interested in talking to her anyway...aside from asking her, "Who's your daddy?"
shr, this thread is already pretty OT, but I thought I'd add that the power loss from the series resistance of using too-thin speaker wire is just one of the problems (and actually a minor one at that). More problematic is the fact that wire with too much series resistance can actually change the frequency response of the speaker. This is because a nominal "4 ohm" impedance is actually a greatly varying impedance by frequency (perhaps from 3 ohms to 200 ohms over the audible range), and the straight-wire resistance of the speaker wire will relatively affect the impedance much more where the impedance is low to begin with.
This is the only way that "high end" speaker cables can legitimately alter the sound, by the way--by providing unnecessary resistance, capacitance, or inductance.
Twisted-pair wiring does greatly reduce inductive crosstalk, but as mentioned, this will have essentially no effect on speaker wire.
