The speakers user by the home users had evolved very much in the last decades. Today you can buy some very good and advanced speakers, capable of giving a high quality sound, without even being too big. There are many types of computer speakers, in different shapes, sizes and prices. Each speaker comes with its unique features, and considering these features you can sort the speakers into different categories. Some of the categories are: center channels, satellite speakers, subwoofer, floor standing speakers, wireless speakers , outdoor speakers and others.

Considering the range of sound they give, the center channels will give mostly the high frequency sounds, the satellite speakers will give the mid range sounds and the subwoofers will bring the low and deep sound frequencies (the bass). Whether if you are using some simple stereo speakers, or a center channel combined with satellite speakers, you will approximately have the same sound. The big difference in sound will be made by the subwoofer.

This speaker will bring a new dimension to your music, movies or games. When having a powerful subwoofer and listening to some music, you will easily get the same feeling as being in a night club. Or when you are watching a movie, due to the subwoofer, you will feel just like if you are at the cinema. The subwoofer will give the low frequencies and will make your windows to vibrate when playing a powerful song, or when watching a movie and hearing an explosion. Usually the best place to put the subwoofer is in a corner, under the desk. Some subwoofers are larger, others are smaller but usually they will fit easily under your desk.

Most of the major audio equipment producers are also having a few subwoofers in their offer. So today we are going to take some examples of home audio subwoofers from different companies, and discuss more about them.

Let’s begin by presenting a subwoofer from the Tivoli audio company. We’ll take the Model Subwoofer. This speaker has a 5 ¼ inch bass driver and an internal amplifier with 20 watts. The design is quite simple and elegant, and is made out of wood, making it look just like a piece of furniture. It’s not that powerful, having a total power of 20 watts, but this subwoofer was not even made to rock your house and to shake your windows. It was designed to subtly enhance the music you are listening to. On the subwoofer you will find 2 knobs, one that is for volume and the other to turn it on or off. It even has a special feature called Auto on / standby, and this will make the subwoofer to automatically turn off when there is no signal, and to turn on when it receives signal. The price for this device is 160 dollars, and you can buy it in two different designs: black ash silver or metallic taupe.

Now let’s choose an expensive but also powerful subwoofer. One of them is the ES 250 P subwoofer from JBL. It comes with a price between 500 and 600 dollars, but it also has an amazing power of 400 watts RMS. This great power, combined with the frequency response between 25 hz and 150 hz will mean that this subwoofer will really rock your house, and make your whole body to vibrate when sitting close to it at high volumes. It will also annoy your neighbors, so be careful with the volume level. The design is black and simple and it is not so large. It has dimensions of 502 mm H x 400 mm W x 428 mm D / 19-3/4 ” x 15-3/4 ” x 16-7/8 ” and a weight of 19 kg (43 lbs).

Next we’ll discuss about a subwoofer from the McIntosh company, the XLS 112. This one also has an amplified total power of 400 watts, meaning that it is quite powerful. The design is quite simple and elegant with the grill on, but if you take it off you will reveal a 12 inch woofer, that will make the subwoofer have a more aggressive look. It has a total harmonic distortion of 0.03% and a max harmonic distortion from 250 milliwatts to 400 watts. The weighted S/N ratio is 100 dB and the input sensitivity 0.4 V. It has a low pass filter of 40 – 120 Hz that you can change from a know located on the rear panel. It is not that big, with dimensions of 15-1/2 “ (38.1 cm) H x 15 “ (38 cm) W x 15 ” (38 cm) D and a weight of 95 lbs. (43 kg).

Another great and powerful subwoofer is the VPS 210 from Boston Acoustics. This subwoofer doesn’t even have the classical square style look, and it looks quite different and also nice. Even the design might tell you that this is a small and quiet speaker, you will find out that it is exactly the opposite. It has an amazing power of 500 watts, meaning that it will make your house to shiver. No bass note will be unfelt, no matter what kind of music you are listening to.

Some companies are offering individual subwoofers, while others are integrating their subwoofers in 2.1 or 5.1 audio systems. So whether if you want to get an individual subwoofer or a sound system, you will have many options to choose from. The subwoofers presented today are just a few, and there are so many more on the market. So if you know some other good subwoofers, tell us all about them.

The world we live in is characterized by technological development and people nowadays accept technology as part and parcel of their lives. As a general rule human beings seem to cope quite well with technological research but they are not aware of the fact that little by little they tend to govern their lives according to the latest breakthroughs.

However, technology is not meant only to make peoples’ lives easier but it also has an entertainment function. We include in the category of entertainment technology home audio equipment. Nevertheless, there are a lot of people who are not acknowledged with the secrets of this type of technology.

First of all, you should know that there is no difference between home cinema and home theatre. They have the same meaning and the same function. Focusing on a definition for the two terms it must said that home theatre was developed as a smaller theatre built in your private home, intended to mimic the “cinema experience”. But you should know that home cinema is, actually, the basic field of home audio equipment. This kind of equipment is composed of a wide variety of devices, such as audio electronics intended to home use, like home stereos and surround sound receivers which became the modern mark of home audio equipment. Thus, there is no clear-cut distinction between home cinema and home theatre but they are featured as accessories, and not as standard equipment. Home audio equipment functions as a device of enhancing or replacing your standard equipment. The composition of this type of equipment is quite simple.

The AV receivers are often viewed as the home entertainment system, functioning as the sounds amplificator and serving as the hub of your entire home-theatre system. It is common knowledge that for an excellent “cinema experience” you need a front video projector which takes a video signal and projects the images on a projection screen by means of a lens system. All the modern projectors have the capacity to correct the inappropriate curves or blurriness, using a very bright light in projecting the specific images. The convergence device which combines the feature of a personal computer and a media center software which develops video and music playback is called home theatre PC, HTPC or media PC. Media centre usually has a 10 foot user interface designed to be used in living-room TV and a remote control.

Moreover, there are few types of home theater, such as backyard theater, defined as a version with a screen which is foldable, a projector and a pair of speakers, but this home theatre relies very much on your backyard space. Then it is home theater in a box, a combination of DVD-Video or Blu-ray Disc player and multi-channel amplifier, including a surround sound decoder, a radio tuner, some speaker wires, certain connection cables, a remote control, a set of five or more surround sound speakers together with a low-frequency subwoofer.

On the whole 21^st century is the century of modernization where home audio equipment is a piece of the puzzle technology represents. If now this kind of equipment is still seen as a fashionable one, soon it will become a common issue. Just take into account the fact that surround sound formats were used in movie theatres dating back to Disney’s Fantasia and became available to consumers in the late ’80s.

When it seemed that you just have bought your stereo system it just became obsolete and you wonder how did this happen. Well it was quite simple, DVD technology took over the VHS home movie land and stereo was ‘out’ as the attainable home theater option would become surround sound. The speakers that you would need to achieve a home theater you could easily purchase becoming a minimum requirement. A front left and right speakers, a center channel-speaker, a pair of surrounds and a subwoofer.

This is all you needed to enjoy a movie with the comfort of a movie theater in you on room. Just too make sure, the pieces work together they were timbre matched. Although the surround systems is very wide spread there is also a chance for the stereo speakers because the vast majority of the music purchased today is stereo, this meaning two-channel, in nature and robust stereo speakers will offer a much better reproduction musically speaking , front, left and right speakers than the home theater system.

The difference would not be audible to mist listeners although they might not be a perfect tonal match. In the past subwoofers were seen only in the cars of music fanatics and audiophiles but now a days with the explosion of the home theaters they are taking their ranking place in the top 5 audio gadgets to have home.

These days most subwoofers are active, meaning they have a built in amplifier that will need to be plugged in so take this into consideration when you place it around the house. When you shop for them, make sure that you like how they hear but you should never leave sight of the fact that an important element to this transaction would be the size of your listening room.

In a small room you will never use huge speakers at their fullest capacity as they you be heard in a store or a supermarket but at the same time small speakers that will sound good in a little room at the store will sound weak.. When you make your purchase make it with a good return policy being certain that you will have the possibility to search for the right set of speakers until you have found the ones that are good for you.

TRW-17 Rotary Subwoofer

Bogdan Alex — Fri, 21 Mar 2008 13:55:22 +0000

The 500 W subwoofer doesn’t sound that satisfying anymore and you got big plans for your neighbors. Then the TRW-17 rotary subwoofer is the thing for you.

TRW-17 is nothing like any subwoofer you’ve seen. It’s more of a fan-like device: check out those cool rotating fins! Inventor Bruce Thigpen from Eminent Technology says this is considered to be the world’s first true infrasonic home theater woofer. As you might know, conventional subwoofers roll off rapidly below 20Hz and the human ear can’t really pick up those frequencies either. But the human body can feel the vibrations. The rotary woofer has enough acoustic output to move an open door back and forth and it can even find resonance frequencies of walls and ceilings in a room. If you want to hear and feel the 4-5 hertz fundamental frequency from a helicopter rotor, the low frequency rumble of wind, the space of a concert hall or infrasonic information contained in an explosion or in the sound of an earthquake, this is the only woofer technology that can provide total immersion.

Here are some technical specs:

- Amplifier Requirement: 200 watts @ 8 ohms Impedance: 8 ohms
- 0Hz – 40Hz Frequency Response – 1Hz – 30Hz +/- 4dB
- Suggested Crossover: 20Hz @ 18dB/octave
- Sensitivity 94dB 1 watt 1 meter @10Hz
- Maximum Acoustic Output: >115dB between 1 and 20Hz.
- Distortion: Typically 3% or less between 1 and 30Hz @90dB

But be warned! The rotary subwoofer may also find resonating frequencies of you internal organs if you get too close to it. Anyhow, the device is still in the prototype phase and needs a little more adjusting. We might actually get one of these in the next couple of years.
