What would happen if you use a shielded cable as a speaker cable?

There is a great deal of debate about the type of cable that should be used for speakers. Some say it should be large diameter single strand. Others maintain that it should be multi-strand. Still others claim that the conductors should be a certain spacing, have a specific insulator and more.
In reality, the main requirement for speaker cable is that it should have a low resistance compared to the impedance of the speaker. The spacing, stranding and the lay up of the cable make little or no difference to the signal that reaches the speaker. There are cables designed specifically for speakers that are effectively co-ax cables with a center core and an outer screen as the return.
Although most screened cables are not recommended for use as speaker cables, virtually all cables will work if the cable length is short. Speakers can draw a high current and small diameter cables can suffer from heating at high power levels. For this reason more than others, a small shielded cable is not the best choice.

What is the difference between a shielded and an unshielded speaker cable?
The difference between a Microphone (shielded) cable and a normal speaker cable is that, When we use a microphone we use a balanced or shielded cable (with the three pins, XLR or cannon), not a normal two wire speaker cable. We use this because the single coming from the microphone is at mic level, below LINE level (less than 1 volt). The shield on the mic cable is connected into the mixer or amp. The shield wire (RF, Radio frequency interference) single its 'waves' are then flipped (reverse phase) to cancel the interference out, any excess interference is then taken to the earth wire. With out a shielded cable you would hear annoying interference eg. The typical phone beep (please turn phone off). Speaker cable does not need a shield because the signal coming into the speaker is above MIC level and RF interference can't get in (it isn't loud enough) so there is no RF interference and no need for a shield. Hope that has been a help!
Where in a vehicle would you find a shielded cable?
In various places - electrical wires and cables are shielded to stop wearing through, or getting wet, the hand brake cable is also shielded to prevent corrosion, was there a specific cable you wanted to know about ?
Can you tin the screen on a cable?
what would happen if you tinned the screen a cable
Are all sub woofer cables universal?
The simple answer, is NO. It depends on the actual connection. From the head unit to the amplifier, it typically is an RCA cable, but if your using "Speaker level inputs" then it would be speaker wire. (with a special harness). However, if your hooking up a Subwoofer to an Amplifier, depending on the guage of wire, Yes. They are universal. Many people typically just use plain speaker wire, however, many use special "Shielded" wire for subwoofers.
What is the difference between UTP and STP twisted pair cables?
* UTP for Unshielded Twisted Pair * STP for Shielded Twisted Pair * FTP for Foiled Twisted Pair * S/UTP for Screened Unshielded Twisted Pair * S/STP for Screened Shielded Twisted Pair * S/FTP for Shielded Foiled Twisted Pair* UTP cable has no shielding, only an insulation around the cables * STP cable has a metal shield around each twisted pair, all pairs together are in the cable covered by insulation * FTP cable has a metal shield around all pairs - "the cable"- together * S/UTP cable has a metal shield around all pairs - "the cable"- together(or would be the same as FTP) * S/STP cable has a metal shield around each twisted pair, and a metal shieldaround all pairs - "the cable"- together(or would be the same as S/FTP) * S/FTP cable has a metal shield around each twisted pair, and a metal shield around all pairs - "the cable"- together(or would be the same as S/STP) * UTP is unshielded, that's simple. * FTP and STP are ofted intermixed, sometimes S/UTP is also thrown in. In general it means the cable is shielded in one place. * S/FTP ans S/STP are of course often intermixed, both should get you a double shielded cable. * Unshielded twisted pair cable will do just fine if there are not too much electromagnic interferences (EMI), that's what the twisting is for. * Shielded cable will protect your signal better from interference. Though there are no guarantees of course, if the interference source is too strong it'll still influence things.Things like big electro motors (an elevator engine), powerfull speaker systems (festival rig), strong light installations (that same festival rig) or a nearby high-power cable are some examples of interference sources. * Evidently unshielded cable is typically more flexible then shielded cable. * I have no idea what the practical difference between FTP and STP cable would be, but it might have something to do with the flexibility rather then with the shielding effectiveness.

Who serves if speaker of the house cannot?
A new speaker is elected if the speaker can not function.
What is the difference between speaker cables and instrument cables?
Speaker cables may not necessarily need shielding if legnths are kept short. Istrument cables are shielded and kept to short stadardized lengths to prevent the introduction of noise which would affect the accuracy of the test reading.
Where can you get high-quality but inexpensive speaker wire in Canada?
There are audiophiles who believe that the type and the manufacture of speaker cable is critical to sound quality and they are willing to spend several thousand dollars in some cases to obtain the "best" speaker cable. This answer ignores the audiophile community as they would not seek an answer to the question of speaker cables in a forum such as this. Speaker cable in its basic form is there to pass electrical energy from an amplifier to a speaker. Generally, the bigger the copper cable, the better it will do the job. For that reason, low cost solutions often use mains power cable. A mains flex rated for 20 to 30 amps will work well and will not break the bank. Take a look in hardware stores for an endless supply of mains flex. Alternatively, dedicated speaker cable can be bought in any electronics and hi-fi stores although the cost of speaker cable in stores can be considerably higher than very similar specifications of mains flex.

How do you know if a speaker is magnetically shielded?
The only way I can think of is by detecting the presence of a magnetic field around it. Of course, you can simply put it near your (CRT!) monitor and watch if the colors get twisted around, but that's what you try to avoid, right? Still, if it was sold as a computer speaker, it probably is. If you've got an old black-and-white TV set somewhere, you can swing the speaker around it without fear, it can't harm it, and if the picture doesn't distort, it's shielded. If you've got an LCD monitor, it doesn't matter, they are not affected. Or you can just open the speaker enclosure and see if the speaker magnet feels significantly magnetic to a piece of iron. Shielded speakers actually have another magnet stuck to their back, that cancels out almost completely the actual speaker magnet's field. The two magnets are oriented such that they are actually repelling each other like mad, otherwise they would add up their fields not cancel them. So there you go...
What does the speaker imagine would happen if he could again hear the symphony and song of the abyssinian maid?
he would feel more happy
Can cat5 cable be used FOR SPEAKER WIRING?
No. The conductor size is way too small. The loss of power to the speaker would be huge, and a decent-sized amp could easily overheat the wires. Bad idea.
