Buy Cheap Stereo Power Amplifiers by Rick Lee

As we all know, amplifier power is measured in watts. If not understood properly, this is commonly a confusing subject. There is a misconception that wattage is directly correlated to the loudness and the volume.

Some people even think that by making the power output than normal results to the maximum volume. But the truth is, the stereo power amplifiers have little to do when it comes to the loudness.

However, power output is relevant to the two main issues - which are the ability of the stereo power amplifiers to handle the volume peaks and the speaker efficiency.

A music lover knows that music is dynamic, It constantly changes in frequency and level. He prefers stereo power amplifiers in his car because it allows him to understand the dynamic nature of the music he´s listening to at its best.

Whether the music be performed live with instruments or in an acoustic setting, the stereo power amplifiers provide the listener with the range that he is looking for. The quiet passages and the loud crescendos are clear.

There are also the in-between quiet moments then the loud highlights. The stereo power amplifiers accentuate the dynamic range of the music currently being listened to.

When the same music is reproduced through the cars system, the stereo power amplifiers reproduce the similar range in loudness. Whenever this is played back at the normal volume level, the medium and the soft passages of the music need minimal power.

If the receiver had 100 watts of power per channel, like what the stereo power amplifiers have, then the music would be heard better. For example, a cymbal´s clink is heard better in stereo power amplifiers.

The receiver uses only a small portion of the maximum output most of the time. This is another reason why music lovers invest in stereo power amplifiers.

Finally, speaker efficiency or the speaker sensitivity is measured by the speaker´s output that is ranged in the decibels. A specified amount of the stereo power amplifiers utilize this for the listener.

For example, the speaker efficiency is measured alongside the microphone. This is placed a meter from the speaker. When one watt of the power is delivered to the speaker and the level meter then measures the volume in decibels.

The output level then results to measure the efficiency of the stereo power amplifiers. This makes for good listening which is the main purpose of the music lover for upgrading his car´s amplifiers in the first place.

Are You Ready For Cyber Monday? by Kathy Forcey

Before 2005 no one had ever heard of Cyber Monday, but in the last 4 years it has become a massive phenomenon. So what is Cyber Monday and how does it affect you?

In 2005 a website called Shop.org noticed that there was a large increase in the revenue reported by eCommerce stores on the Monday after Thanksgiving. They were the first to coin the phrase that is now used each and every year to describe the Monday after the thanksgiving sales.

While many people are still too scared to put their credit card details into any sort of website, the amount spent online is growing every single year. In 2008 the dollar amount was 846 million, that was 15% more than the previous year. This is only the stores that make their information public so the figure could be much higher.

As well as people spending more every year they are also starting to do their research on it earlier in the year. 2009 will be no different, in fact I think this could be the year that we see over a billion dollars spent online in just one day.

People are becoming aware of how manipulative the stores can be when they are promoting their special offers and when you shop online you are in control with a much better chance of walking away from an offer. When you are in the store and there are people around you going shopping crazy it can be hard to let what you are being told is a bargain go.

If you do decide to shop online this Thanksgiving then you could not only be saving money you could also be helping the environment. Think of all the gas you will save by not driving around town for hours and of course you get to stay in bed!
