The simplest answer is "sure, if you use ordinary electrical wire, a speaker might work"—as long as you have two conductors that are the equal size for positive and negative, you'll receive sound. There are variances in the metals used as well as in the shielding (for some speaker wire, but not all). However, for home recording purposes they are equivalent.
Speaker wire is usually only needed for outdoor speakers or speakers that are being fed from an amplifier with its own power source. It can also be useful for connecting high-current devices to your home audio system; for example, a set of lights requires more current than an iPod does. Otherwise, use normal wiring: If you need two circuits for two independent devices, use separate cables for each circuit. If you're unsure about how to connect something, hire a professional electrician instead!
There are three types of speaker wires: split, twin, and TRS. These names refer to how many conductors are used for each pair of terminals. For example, a "four-conductor" speaker cable has four conductors total—two pairs of conductors that are separated into different paths around a cable sheath.
It's best to avoid using old, broken, or modified speaker cables on your home audio system. They may work fine for small speakers, but larger systems need cables with higher voltages between their terminals to prevent dangerous shorts.
To address the question stated at the beginning of this post, yes, you may use standard electric wire as a speaker cable as long as it has two conductor wires of the same size. If one side of the connection is going to be more loud than the other, there are special cables designed for this purpose.
Loudness is determined by several factors such as output level of the source device and the sensitivity of your hearing. If you connect two devices that are equal in every way except one is more powerful, then you will get more sound out of the less powerful unit. This is because human ears are very sensitive to low frequencies and can hear down to a blood drum beat at 20 Hz.
The frequency range of audio equipment starts at about 20 Hz (drum beat) and goes up to about 15000 Hz (halfway between a G and A above middle C). Anything beyond this range requires separate amplification for each channel. Channels are the words used to describe the three ways that sounds can be transmitted through speakers: from the front left, right, back left, or back right. Most systems have two channels: left and right. Some high-end systems have more than two channels; for example, five-channel systems play different tones into each earpiece so that listeners can locate sound sources.
You may utilize speaker wire for electrical reasons, but be careful. Speakers were frequently linked using basic electrical cables, or "lamp cords," in the early days of home audio. This replacement also works in the reverse direction, and in many circumstances, speaker wire may be used in place of electrical wire. The problem is that you cannot connect two different types of wires in your house network: neither metal nor plastic will tolerate voltage without some form of damage occurring.
If you're lucky enough to have a set of cable with all-aluminum conductors inside its shielding, then you can use these wires as an alternative path for electricity to follow. If other types of wiring are present in your house, such as copper, then this type of cable should not be used as it will not function properly if exposed to moisture or other conditions that might occur inside a home.
The best option is to use solid aluminum cable for all internal connections, including those going to speakers. This will provide a very safe and durable path for electrons to follow. Solid aluminum cable is available from most audio component manufacturers; if they don't supply it themselves, then look elsewhere for your speaker cables.
Yes, however stranded wire has a little greater DC resistance than solid wire of the same gauge (while doing much better at high frequency). You should have no trouble utilizing speaker wire as a low power cable if you can use wire hangers as speaker wire (lol). Actually using two 4-foot sections of speaker wire will give you a 6-foot cable that can handle about 100 watts to each channel.
The problem with using speaker wire for powering equipment is that it's very difficult to get good quality speaker wire. The best kind available is called "substitute" wire because it resembles old style telephone wire and can be used instead of it. This type of wire is made by twisting several strands of regular copper wiring together.
If you look on the back of your TV or stereo then you'll see a cord with one end labeled "male" and the other "female". These are the ends of the speaker wire and they must always be connected together. If not, then this creates a dangerous situation because you would be feeding electricity into dead air space where anything could happen. That's why all speaker wires must be joined together before being plugged into a device.
You also need to pay attention to which way around the wires go in the connector. Some manufacturers label their connectors with the letters "red" and "black" instead of right and left.
You can use speaker wire, but keep in mind that how you hang it and the sort of antenna you design can also cause issues. If the wire has a few of steel strands, you're fine to go for antennas. If you simply use copper and hang it by the ends (and pull them tight), you will gradually lengthen the antenna!
The best sort of antenna is one that matches the height of whatever building it's attached to or hangs from. This means that if you want an antenna that reaches high into the sky, you'll need something like a satellite dish or even a radio tower. But if you want an antenna that can pick up signals from low down in the sky, like a mobile phone mast or television transmitter, then you'll need something shorter.
It's difficult to provide general rules about what will work best where, because it depends on so many factors such as the type of signal you are trying to capture, where it is coming from, and whether you are looking at signals that travel over long distances through air or more local ones that follow streets and buildings. But the main thing is that if you don't know what kind of antenna you need, you should probably get help from someone who does!
