Guide to How to Buy Cheap Computer Speakers

Not everyone has the know-how of can be bothered to be all technical when it comes to choosing computer speakers. This guide shows how to sift through the information unnecessary to the average consumer to come to the right decision.

Hopefully you’ve read my previous entry on what to do before you even start looking for speakers. Narrowing down your choices will make things a lot easier. Having your core needs pre-determined makes the selection process more about fulfilling supplementary criteria, rather than the basic requirements. Furthermore, you don’t want to spend your precious money on a set of fancy speakers only to find you don’t need all that power. I mean, that’s why we’re looking for CHEAP computer speakers here aren’t we? That said, at this point you would probably start comparison shopping; that is, searching at different online retail outlets for the best deals on the best products based on prices and consumer reviews. This is a fairly extensive process that can be quite time consuming and overwhelming.

The SMART way of looking for your ideal product online only consists of one step: compare reviews and opinions. That’s about it. If you’re just a casual user, you shouldn’t have to know too much technological jargon involving S/N ratios, frequency responses, drivers or even power supply wattages. Think about it, if people feel qualified enough to post a review, chances are they’d already know enough about all these. Even if they’re not, you’re getting an honest review from a layman just like most of us. Sure, there are bound to be some dissenters who only put extreme scores due to a personal experiences but it’s easy to weed these out.

A good way of starting would be to post in an audio or computer-based forum like Audio Forum for opinions, or browse through existing threads. Look through recommendations and search them at review sites like CNET and Test Freaks for professional and user reviews. Narrow your options further, and pick out the ideal one. Of course, this site also does all that, without the hassle of combing through a million other web pages, but it’s good to keep your options open.

If you want to be more specific about it, there are other things to look out for when searching online. It is still most efficient to read through reviews when taking these into account, however. Without getting into technical specifics, I’ll try to break down what else you should be searching for when browsing through your options:

1. Brand

No one wants to be labeled a brand-whore, but in the case of electronics it is often prudent to go with trustworthy brands. There’s no guarantee that they’ll be any better than no-name alternatives but in general this is true. Electronic brands build their image over years of high performance, so if it has a good reputation you can be certain it won’t be a bad product. Also important is that good brands often offer much better customer support, both in terms of warranties and servicing issues. With electronics, it would be preferable to get at least a year warranty on products in case of faulty wiring or parts, and support centres should be easily contactable. In addition, if it is a well-known brand/model, you can easily post a question online if you have a problem and people would be able to help you more easily as some might have encountered them before and may help in resolving the issue.

Examples of common, established brands for computer speakers are Creative Labs/Creative Technology, Logitech, Altec Lansing, Cyber Acoustics, and JBL.

2. Looks

Some people consider this an excessive superficiality, while other consider it the crux of their choice. If your entire room and/or computer setup is color-coordinated or themed, it might be crucial that your speakers fit in. For better or worse, most speakers are almost always entirely black, perhaps with matte silver accents. In fact it’s often the better choice when it comes to cheap speakers, as the really cheap, lousy ones tend to be this off-white, greyish shade that ages into a disgusting yellowish-brown tinge over time. Trust me, black is safe and timeless. Besides the color, some speakers are uniquely shaped, like domes or phalluses or otherwise. If that’s your thing, it would probably severely limit your choices but they do exist.

3. Controls/Peripherals

This is a bit more important. Most speakers come with a power switch and volume control, but you may need more utility controls on the speaker set itself. These may include basic EQ adjustments like bass and treble, central/surround volume control, a manual subwoofer control (very important in my opinion) and left/right balance. If you’re in a situation where you need to constantly switch between headphones and speakers, it would also be useful to have an audio-out/headphone jack so you don’t have to inconveniently reach around behind your PC to unplug your speaker’s cables. Many speakers these days also have an audio-in or MP3 jack for your headsets and MP3 players respectively.

4. Audio Quality Testing (optional?)

Now, what I mean here is if you intend to go to retail outlets and test speakers out. While this may seem like a good idea, the fact is most computer/electronics stores that sell computer speakers aren’t always the most conducive environments for sampling audio. The speaker positioning is weird, the acoustics are bad, the surroundings are noisy, you can’t concentrate and most importantly, it’s not a good representation of where the speakers are going to be after you purchase them. Still, it may be good if you’re narrowed down to a couple of choices and you just want to decide based on your physical exposures to them.

If you do get the chance to test them out in decent conditions, or if you just want to test your speakers after purchasing, these are what to look out for:

– Firstly, be sure to try them out with different types of audio; this means different genres of music, movies, games etc.

– Make sure there isn’t any distortion or noise produced.

– Highs should come out crisp but not annoying. They should not be weak and tinny.

– Mids should be clear, smooth and pronounced. The majority of the sounds produced in music tend to come out in the mids.

– Lows should be tight and punchy, not overly muffled and boomy. If you have a subwoofer, make sure they don’t sound too separated from the satellites, and should be the sole providers of the low end rather than involving the satellites. Cheap subwoofers tend to sound muddy and undefined. If you’re just using a 2 speaker setup, make sure you can still head the bass clearly as cheap 2.0 speakers most obvsiouly lack in this area; you should feel the lows ‘hitting’ you in the chest.

– The sounds should meld together without any overpowering elements. Especially important with subwoofers. If they feel a bit off hopefully there is an EQ setting in the speakers or in software that can remedy that.

As I’ve mentioned and as evident by this somewhat banal list, comparing reviews online really is the definitive way of searching for your best option, especially if you’re not into comparing technical specifications and all. It’s best not to stick to one site, as one person’s opinion might not reflect yours. Compile a number of reviews, both positive and negative, professional and user-generated, and decide which is for you.

Modern Computer and Its Features

There has been a debate as to when or who really invented the very first computer. The answer would be so vague that it truly depends on the person whom to relay the question to. Historians may refer to abacus as the very first computer invented and used by human. This was discovered around 5000 years ago in Asia.

The very first computer with modern use was discovered during the Second World War. This was when a group of engineers and scientist came up with a digital calculator that was originally named Electronic Numerator, Integrator, Analyzer, and Computer at the University of Pennsylvania.

This electronic device has a number of vacuum tubes-18,000 to be exact. The main feature of first invented computer was its capability to sum ten-digit decimal up to 5,000 in just one second. It has a total number of 1,500 crystal diodes. It also had approximately 10,000 capacitors and the parts are fixed with 5 million soldered joints. It was extremely heavy and weighed thirty tons and run over 150 kilowatts of power.

It functioned for a short time after the tube failed to run during the period of shifting temperature. The first invented computer was also able to function better when the engineers and scientists let the computer on for a long time. The tube failure reduced considerably and the rate even improved.

The interesting feature of first invented computer- Electronic Numerator, Integrator, Analyzer, and Computer was its capability of being reprogrammed. This allowed this electronic tool ton also resolve computing problems. It was even used for some government missions and research. At that time, this computing device was considered as an extremely advanced tool that was incomparable to the existing revolutionary calculators. The drawback however is its incapability of storing information which challenged the existing scientists then.

Why Recycle Computers?

In today’s world you often here of recycling to go green, save the environment, and contribute to a more eco friendly society. It may seem like a trend and get annoying and preachy at times but what it really is about is protecting your environment and your health. Recycling is very important to keep our landfills free from overflowing and keep harmful things from ending up in them, which ultimately end up in our water supplies. It is important to do your part to recycle especially when it comes to electronics and more specifically computers. Electronics and computers that are no longer used are referred to as e-waste. This type of waste is a growing sector of waste in today’s landfills and is only expected to rise dramatically over the next few decades. The recycling of computers drastically cuts down on the number of harmful ingredients in landfills. Computers are full of harmful chemicals and metals that if left in a landfill will end up the in water supply which not only damages the environment but human life itself.

As technology advances more and more with the times, so does the obsoleteness of old computers and technological devices. These old computers end up getting thrown away and end up in landfills polluting the environment. What most people don’t consider is those computers actually are made up of harmful components which can harm the environment. Computers are often made up of and contain heavy metals such as antimony, silver, chromium, zinc, lead, tin, copper and mercury. Monitors also contain lead to protect users from exposure to radiation, which is very toxic. Other harmful things computers contain are cadmium and mercury, both very dangerous. If these things end up in the water supply and ecosystem imagine the havoc they could wreck on the earth, human and animal life.

Electronic Keyboard

An electronic keyboard is a keyboard instrument that uses electricity to amplify the sound. Electronics keyboards are mostly used in musical instruments such as synthesizers, pianos and electric organs.

Electric organs are one the earliest instruments which used an electronic keyboard. They used oscillators and frequency dividers along with a network of filters to produce desirable sound in waveforms.

Keyboards reached a major milestone with the development of the synthesizer in the 1960s. Now, various advanced types of synthesizers using electronic keyboards are available in market.

Many instruments which have electronic keyboards are equipped with Musical Instrument Digital Interface (MIDI). This helps in the diversified use of the electronics keyboard. Some keyboards are not attached to any instrument, but are only MIDI controllers.

Electronic keyboards make it easy to create music. Most of these keyboards can also be connected to a computer for performing multimedia activities. However, you may require certain software to ensure that your electronic keyboard is compatible with your computer.

Electronics keyboards are available in a wide variety of shapes, sizes, colors and price ranges. There are several web sites which sell them online. The electronic keyboard industry has been growing at a rapid pace over the last couple of decades. New technological innovations ensure that the old models get obsolete quite quickly in this market.

There are several companies which sell only secondhand electronic keyboards, but with a warranty. If you try hard, there is every possibility that you can get a good deal. However, if you can afford a new one, that is the best option. And do not forget that with advent of Chinese electronic equipment in the market, an electronic keyboard has become an affordable item for most people.
