Question about Sonic EV SonicXS 4.1 Computer Speakers

No sound on EV SonicXS 4.1

I just purchased a "used" EV SonicXS 4.1 - I only connected the front left and right speakers (not the rear) and there is a light on the right front control speaker, but - there is no sound - not even a hum. The fuse is okay. Can I check inside the subwoofer for a power supply?

The headphones are working and connected to the same port with a splitter.

Many thanks.

    Is there any problem with using a 4.1 system on a 2.1 setting with only the front speakers?
    I tried both 2/1 and 4.1 settings - there is no sound whatsoever. That leaves the subwoofer with its amplifier as the culprit, but what can I accomplish by opening a very secure box and poking around inside?

Good day Idn2000

you may check also in the manual your actual conection, and see if is the right, then check on control panel and speaker setup, for 4.1 setting. if the speakers don't work,at back, something is bad inside the controller, on sub. be carefull opening and moving things inside, but you can check that .

I installed a new Sony CD player in my 1996 Toyota Forerunner and the speakers won't work. The player has power but there is no sound. I did not use a wiring harness but I did have the wiring diagram for...

Be sure that the wires are connected correctly. If no sound comes out could be speakers are bad, but highly unlikely that all four would be. Could be the stereo amplifier is out. You could try using an amplifier to connect the speakers. One other option run new wire to each speaker to make sure wiring is still good.

I bought these x 240 speakers used. do i need a driver to run them? where do i connect the plugs, black and green?

These are "decent" quality 5.1 speakers, new were on about $100.00 to $150.00, have two years warranty from time of purchase.

Now, to your question, you will not have 5.1 "surround sound" effect with standard sound card, standard sound card will provide only three speakers sound, rear speakers will not connect.

Connect speakers as follows:
1. Audio from PC, orange, green and black connecting to front right speaker.
2. DB15 (D-SUB) connecting to subwoofer, subwoofer is serving as mixer, power board, amplifier and connection box
3. White plug is connecting to front left speaker
4. Red is connecting to front centre speaker
5. Black is connecting right rear speaker
6. Yellow is connecting left rar speaker.

Establish location of the speakers, from experience in ideal world:

1. Sub should be on about your knee level or below,
2. Front centre speaker should be about twice your hight distance from you, on front and slightly above your head.
3. Front left and right speakers should be at about 45degree from your axis, at distance of about 1.5 your hight and on the level of your head or slightly below.
4. Rear left and right speakers should be located similiary to front speakers, on they level or slightly above them, again, about 45degree from your axis.

Location of the speakers is more actually important than it is assumed, total sound immersion is not possible without proper speakers installation. Head in these instruction meant a location of your head while you are listening to your music or recording not whil eyou are standing.

In reality... hang them higher than your head in four corners of your room, front centre higher than sides, woofer lower than sides and below front centre, if they interfere with each other - increase the distance. I hate reality...

After speakers are connected:
1. Plug power cord in,
2. Turn all sounds totally down, including subwoofer
3. Increase sound on PC to maximum, let play any known to you music, tufftuff or bach, whatever, do not bother with metallica as you cannot discredit on it correct levels.
4. Increase subwoofer volume, holding one hand on the front of the grill till you get some vibration from it
5. Increase sound on centre button of the right fron speaker till you achieve equality of the sound
6. Decrease sound volume on your PC to about 60% - 70%
7. Increse subwoofer volume till you feel sound on your hand in front of the speaker.
8. Increase sound volume on front/rear speakers as required.

Hope that short intro solved all your speaker problems, enjoy! if you require any additional help, do not hesitate to answer to this post with request.

To install 4 speakers

If your car player has got provision for front and rear there is not issues. You can connect two speakers to the front and two to the rear. However if there is no connection you can connect the front right in parallel to the rear right and also the front left to the rear left.
If you want to use a tweeter use a bipolar capacitor of about 2.2mf / 50V in series with the tweeter to tbe connected to the left and right connections.

I only hear sound out of two speakers........

Have you set the computer up for 4.1 speakers in the audio software? Go to start control panel and click on sound's speech and audio device's, then click on sound's and audio device's. A window should pop up with a load of menus at the top, click on the one that says volume. Where it says speaker settings click on the advanced button. Click on the menus until the picture lookslike your system you have.
