The Right Car Audio System For You
Regardless of your car audio listening habits: broadcast radio, satellite radio, or CDs, finding the desirable speaker combination for your automobile will make your audio experience a positive one. Finding the right system may take some effort and research, but it will be worth it. Improved components which add greater functionality of car audio system means you should know about certain components. These components are speakers, sub woofers, tweeters, amplifiers, ipod adapters and more.
Speakers
Speaker approaches are very important because they are the units that actually reproduce the sound from electrical energy.
The right speakers for your auto audio system are extremely critical, given that they are reproducing the actual sound from the stereo itself. When buying speakers, only consider the higher end. Here is what you need to know, and what to look for:
First, let’s start with the types of speakers that you’ll encounter in the car audio world.
A woofer is a large speaker which will reproduce the lower frequencies. The mid speaker is, as its name implies, a medium sized unit which reproduces the middle frequencies. And the tweeter is small and will reproduce the higher sounds.
A sub woofer will give you another dimension in bass: they reproduce the lowest spectrum of the sound. And there is a also a supertweeter which will give you the highest sound in the spectrum.
When you buy speakers, you may be actually buying a “package” of speakers, encompassing some or all of the above. Or, you could purchase them separately.
There are other variations of these speakers available as well. If the car sees a lot of use as well as wear and tear, then buying higher quality components is a great idea.
There are many factors that need to be considered in placing the speakers in the correct position. Basically, they split music signals into separate frequency ranges and sends them to speakers that are designed to best reproduce each frequency range, you can vary the crossover points and adjust the level of separate speakers to achieve the best overall sound in your vehicle.
Power
Amplifiers are devices that take a teeny tiny audio signal from a pre-amp, some power from your battery, and pass it on as a big audio signal to drive speakers. To get the cleanest sound, it is absolutely essential to have as much power as you can afford. It delivers power with clarity.
Factory fitted radios (standard fit radios) in the past had relatively low power outputs of about 3 to 5 watts. Compare this to after market radios where the basic models start at a power output of 45 Watts x 4.
By providing a maximum power of 45 watts, they belong to the class of highly efficient amplifiers that are up to 90% power efficient. It makes the most efficient use of power when compared to other amplifier classes.
Components
A car audio system is a combination of components such as head units, amplifiers, speakers, and auxiliary input devices. A word of advice: if you are supposed to be paying for new car audio approach from an after market dealer, make sure you see the box, the price and installation materials before the company installs the your car audio approach. This way you are assured of getting what you paid for.
If the quality of the audio in your car is important to you, be sure to consider these ideas. Many of us spend a great deal of time in our cars. It is worth the effort to make sure you get what you want.
Wireless Technology for Home Or Work
10 years ago the Internet was quite uncommon. Today the Internet has become a vital part of our lives, work, economy and study. The same can be said for wireless technology. 5 years ago virtually non-existent, today your WIFI finder goes crazy with all the available wireless networks. I find it perfectly normal now to go and sit outside on my terrace and wirelessly surf the Internet. And WIFI technology is not just limited to connect computers to each other or the Internet.
A whole range of utilities and gadgets are jumping on the WIFI train. You can have a baby phone camera system that uses your home WIFI network to transmit the images & audio from the camera to your Computer or PocketPC. Or what about the WIFI rabbit? It is a toy rabbit that is permanently connected to the Internet. You can talk to it, giving it commands. It can talk too and Alert for incoming emails, SMS, phone, etc. You can have it read out your email, the weather, information of the stock market and so on.
One of the coolest applications of WIFI is IMHO the airport express access point from Apple. It is a wireless access point, effectively creating a wireless network. It has a USB port so you can connect a printer to it and print wireless. But the absolute coolest thing about it is it’s mini jack audio port. Here you can connect any speaker system or HIFI equipment. So basically for €129 you can have a WIFI network that can print without cables and you can play your music wireless, without cables! And that is not all. With the latest version of iTunes you can now use multi speakers. That basically means that you can connect various Airport Expresses together and have the music come out all of them simultaneously. At home I know have music coming out of the living room, bedroom, office and kitchen all at once!
