Advice 1: How to make active speakers

Called active acoustic system, which contains built-in amplifier. It takes up less space than speakers and amplifier made in a separate building. If you want an active speaker system you can convert an ordinary.
How to make active speakers
Instruction
1
Take a conventional speaker system of any type, designed for input power of several watts. It should have a folding design. Inside each speaker there should be enough space to accommodate the amplifier.
2
Note that the classical design of an active acoustic system involves the placement of the stereo amplifier only one of the speakers. Sometimes it also placed the power supply. The second column is passive. Such a solution allows, first, to perform both amplifier channels on a common circuit Board, and second, to reduce the number of cables to just three (input, power, output on a second column).
3
Amplifier and power supply use the finished, miniature active speaker system less power. It is known that the sound quality is determined by speakers to a much greater extent than the amplifier. Therefore, finding a new "home" in the form of much larger speakers, the amplifier will begin to sound absolutely on-to another. Importantly, the resistance of the speakers in large columns was less than in those from which you extracted the amplifier. Remove amplifier with volume control, cord to connect to the signal source, etc.
4
In the case of the column within which to house the amp, drill a hole for the power button, volume control, led, input cable. If you fix the power button from the old columns will fail due to the significant thickness of the shell new, replace it with a toggle switch.
5
The output of one of the amplifier channels connect directly to the dynamic head of one column (or to the crossover, if it is multiband), and the other to the long cable. It connect to the input of another column.
6
Carefully inspect the installation. Make sure that under no circumstances components will not be displaced, causing a short circuit, and that when you close the case, neither the contacts nor the dynamic magnetic heads do not touch the components of the amplifier. All parts and units secure. The primary circuit of the power supply, place away from the secondary, so that they under no circumstances could not relate to each other. Next to the power supply and amplifier, drill some vent holes, not conspicuous.
7
Close the housing of the column where the amplifier is located. Connect the finished system to the sound source and to the network. Enable and test it.
Note
Learn to choose the right speakers for your computer. Speakers are no different from conventional speakers, and are also divided into active and passive. The price of these speakers is minimal. Active speakers have the amplifier, which allows to achieve high quality and loud sound from sound card.
Useful advice
If you need perfect sound. Note that there is no reason to buy expensive multimedia speakers for computer if you're going to connect them to the built-in sound card. Active or passive speakers? If you are looking for in network material for choosing speakers for your computer, you probably already ran across a discussion of the two types of speakers: active and passive.

Advice 2: How to make a case for speakers

When speakers get old, you want to overwrite them. The sound gradually begins to move in a sharp or crackling sound that brings some inconvenience when listening to that particular music track. In the home make a simple enclosure for the speakers.
How to make a case for speakers
You will need
  • Speakers, metallic fine mesh, glue, tool set, scissors, acrylic, organic glass, compass, pencil, sandpaper, a fan, a box of disk.
Instruction
1
First disassemble the design of columns.
2
Make acoustic wire disconnected from the Board using the connectors.
3
Use templates with which you will be able to cut parts from acrylic. To do this, apply the compasses and pen to future housing had right angles.
4
The finished wall is undercut.
5
Undercut organic glass with sandpaper.
6
Cut a hole for the speaker.
7
If you decided to work with the fan, and you need the mesh, cut to fit the wall of the housing, as well as screws. Secure the mesh with screws.
8
For the manufacture of the grille on the fan, use a box from a disk. Cut out its contours and undercut sandpaper.
9
Cut two grilles for the speakers on the front wall speakers. For this you will need a box from a disk.
10
Connect with glue, mesh and grid to create a front panel housing.
11
At the base should make holes for the wires and LEDs (4 pieces).
12
Glue all parts to the caseand are kindly requested to return all the internal contents of the columns.
Note
Be careful when working with glass and creating patterns. Better prepare a compass and writing materials to all the edges of the future of the housing were smooth.
Useful advice
To get great sound out of the speakers, you need a good case. You can use the sieve as mesh for the front panel.
