Wireless Home Theater Systems Guide to Quality
Wireless home theater systems have their own specialized place. At first you might wonder why you would use a wireless home theatre system when experts say the sound from wireless home theaters is inferior (I can’t hear the difference) and it costs more.
However here are some situations where wireless home theater systems would solve your problems
* You want to listen in any room in your house so you want a wireless theater system
* You want to listen in your garden with outdoor wireless speakers in your wireless home theater systems
* Your listening room is larger than the cables supplied with your 7.1 home theatre system
* You’re in a rented property so you can’t break holes in the wall or ceiling, or install cables under the glued-down carpet. So you must turn to wireless home theater systems.
Why not wire every room directly?
Think of the wiring for a speaker. It goes something like this
The power to your speaker from your home theater receivers is shared out over the entire length. In other words, some of your expensive power goes to the wiring instead of to your speakers. The longer the wires are, the greater their resistance, and the more power they grab.
You can install thicker wires. If you double the thickness of the wire, the resistance goes down to 25%, so the wires grab only a quarter of the power used by thinner wire. However that is only considering resistance of the wires, and inductance and capacitance also increase as the wire lengthens, and the interference picked up from you mains power supply also increases.
So if you can knock holes in the walls or ceiling to install a cable system, you can mount speakers in the nearest rooms, but you’ll probably find that your speakers in further away rooms are very under-powered.
If you spend a lot of time in your garden, then you’ll want to investigate wireless home theater systems and get a professional installation, installing outdoor wireless speakers is a matter of beating anything that the weather can throw at you.
So what’s in wireless home theater systems?
Your central electronics unit is called home theater receivers (or home theatre receivers ) and is a box with masses of signal inputs, some signal outputs, and speaker outputs.
“Wireless 5.1 home theater ” means that you have five normal speakers and a sub-woofer. And as you might guess a “7.1 home theater system” has 7 normal speakers and a sub-woofer to give a complete wireless surround sound speakers system.
Both systems use a center speaker and two side speakers at the front, and a left and right speaker behind the listener. The home theater subwoofer may also be in the center at the front, so it won’t need wireless connections, or it may be in the center at the back where you might need a wireless subwoofer. The extra two speakers in the 7.1 home theatre system are midway each side of the listening room. You would need a home theater with wireless speakers only for any speakers that you can’t direct-wire to your home theater receiver. Your home theatre subwoofer gives you the deepest sounds and sudden bangs and explosions.
Wireless home theater systems for every room in the house is an entirely different matter. If you are satisfied with stereo in the remote rooms, you would want audio transmitters from your signals intended for your left and right front speakers, your center speaker and your sub-woofer. If you want full 7.1 surround sound in each room, you would need transmitters taking all eight speaker outputs from your home theater receivers, but I can’t help thinking that would be a bit of overkill! Naturally you need wireless sound receivers in each room to drive your speakers.
Can you buy home theater systems at bargain prices? Yes and I intend to write posts here about wireless home theater systems bargains as I discover them. Be warned…wireless home theaters for $7000 are bargains if they usually go for $9000, and ones being sold for $50 when the usual price is $120 should probably not be called wireless home theater systems.
