Question about Harman Kardon HK19.5 Computer Speakers

1 Answer

Right speaker stops working

The right speaker intermittently stops working (with increasing frequency). Fiddling with the cable that connects to the left cable seems to fix it, but only temporarily. That leads me to believe there's a loose connection inside. The trouble is, I just fought with it for a half hour and couldn't open the case! Any suggestions on how to get these open without cracking it permanently? My speakers are the black ones that Dell shipped with black laptops (same shape as the white ones, but a different color plastic).

Thanks!

    The left speaker is working, while the right speaker is silent. Disconnecting and re-connecting the wire connecting the two seemed to work for awhile, but then, the right one stopped working again. The connection is either on or off. Right now, the right speaker isn't working.

A couple of years later, but maybe this will be useful to someone:
1. Disconnect the cables (input, power, 2nd speaker).
2. Undo the two screws on the base of the casing.
3. The two knobs can be pulled off. Underneath there are two nuts that hold the spindles to the casing. Undo these.
4. The fabric cover is a push fit. Prise it off the front. If needed, use a (non-metal) tool that won't damage the plastic casing.
5. Under the cover, the two top holes contain screws - undo these.
6. Four screws hold the actual speaker to the casing. The two lower ones are slightly longer and also hold the casing together. Note this for reassembly.
7. You can now gently part the front and rear parts of the speaker housing.
8. To completely separate the parts, you need to disconnect the red and black wires that go the the speaker. The are push fit 'spade' type connectors - a tight fit, but removable.

My problem is similar - loss of left channel. I think the problem is in the headphone socket as wobbling it or inserting non-conducting objects can temporarily restore the channel. These sockets switch off the speaker when you plug in the jack, so I think the switch is faulty. I plan to desolder this part to inspect, repair, replace or bridge the connection and do without the socket.

Hope that helps.

How do I repair


I guess you have tried switching the speaks left to right to check its the speaker rather than the output to the speaker?

If you have it might be worth (If you are able to) opening up the speaker unit to check the wires are still attached and solid, maybe need a little re-solder is needed as the wires are usually very thin.

Why is there a loud humming/buzzing coming from speakers?


most of the time this is caused by a bad ground. Check all cabling from and to the right side satellite and the sub woofer.

Where do I pug the speakers in ? I need a Picture,Show me the picture.


    • 1 Remove the Dell A215 speakers from the box. Place the speakers in your computer area. The speaker with the volume knob is the right speaker and should sit to the right of your keyboard. Place the other speaker to the left of your keyboard.
    • 2 Plug the left speaker into the right speaker. The left unit has an orange-brown plug that connects to a similarly colored port on the back of the right unit. The other end of the cord is fixed to the rear of the left speaker.
    • 3 Insert the two-prong end of the power adapter into an electrical outlet. Plug the other end into the black power port on the back of the right speaker.
    • 4 Insert the main audio cable into your computer. This cable is fixed to the back of the right speaker and has a green head. Plug the green connector to the green audio-out port on your computer. This port may be on the front or back of desktops or on either side of a laptop.
    • 5 Turn the knob on the right speaker clockwise to turn the speakers on and increase the volume. Turn it counterclockwise to lower the volume partially or all the way to turn the speakers off. The speakers should work automatically on any computer with a sound card.
Let me know if this solved the problem and good luck..

Right speaker stopped working?


Hello.
This is a very frequent case and it is not rare.
These speakers usually are not that much of a high quality, so the chances that these speakers (or one of them) will stop working is very high.
First of all, to check that hte speaker isn't corrupted, try making sure that all the necessary cables are properly put in their places:
Check that the two speakers are connected to each other (usually a cable coming out of the back of the speakers).

Secondly, check that your computer has not muted the right speaker:
Go to Start -> Control Panel -> Sound and Audio Devices -> Click "Speaker Volume..." button under the Speaker Settings frame -> Set all volumes to the max (Drag the slider with the mouse to the high right)

If none of the solutions worked, then there's a 99% chance that the right speaker has been corrupted or is malfunctioned. If so, I recommend buying a higher quality set of speakers.

Good luck.

When I do a noise test I get no sound out of the woofer. I am getting no bass from the woofer


These are "decent" quality 5.1 speakers, usually without any trouble.

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 but bass should be hear. Please switvh power off to the speakers and disconnect all cables from spaekers and connect them for best quality 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, control pod is just cable connection to it
3. Connect all cables to they respective speakers

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

1. Sub should be on about your knee level or below, about twice your hight from you.
2. Front centre speaker should be about some distance as sub or bit closer 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 while you 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 speaker, then on sides front speakers 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.

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.

Short in subwoofer wire - Altec Lansing computer speakers & sub


yes, you can splice the cables and put on a new connector, goto radio shack with the old connector and im sure they will have one you can splice right onto it. ive done this many times with varios equipment "headphones speakers etc" it may take a couple of tries to get the wiring right but if its just one speaker there will most likely be just 2 wires, if you wire it up and it doesnt quite sound right, wire it the other way. speakers will work wired backwards but wont sound quit right so if it doesnt, rewire it and it should. good luck and i hope this helps!
