Hello.. I have Creative 5.1 Speaker Set.. have problem with subwoofer shutting itself down after very short using time (30 min).. Tried to change all fuses.. Tried to disconnect all other speakers and computer sockets just to see if it wont shut down just on its own.. but still same result.. advice? Thx

Your burned subwoofer speaker is [16cm] one, magnetically shelded type. If it ahs burned out, before replacing an other speaker, throughly check if there ahs some short to its output circuit. If there is a short, the speaker you replace will also will burn out within seconds after switch ON the set. speaker have a 6Ohm impedence and rated at 60 Watts. Frequency response is 20 to 150Hz. Whe buying one these specifications must be noted. You can open its back cover after unscrewing the fixing screws. Do it very carefully and peacefully. OK.
Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.
Things You'll Need:
* Amplifier * Speaker cable * Extra subwoofer
Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.
Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.
Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.
Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.
If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..
start at the basics, check home circut breaker box, ensure it is still plugged in, check the fuse subwoofer itself. unplug and disassemble, to ensure no moisture or a fried bug is the sorce of the problem, ensure the leads to the subwoofer havent popped off or become crossed, etc etc. hope this helps
Are you using the Creative speaker test program? It usually has a picture of a generic layout of a pc system, with the speakers around it, showing a speaker for each that you should have plugged in. There should be a test button that will play a sound through each speaker. If a sound plays from your center speaker when the subwoofer picture is lit up then you may have a cord plugged in incorrectly on either the subwoofer or on the back of the soundcard. I've ran into this many times. The best way to set up surround sound is to get your speakers placed or mounted on the wall, then run one wire at a time into the subwoofer, to ensure that the front left is hooked into the subwoofer in the front left, front right into front right, etc. Then once the speakers are hooked into the subwoofer start running the outputs from the subwooofer one at a time into the sound card. After each connection run the test program and watch the pictures light up as the sound plays, and make sure that the speaker playing sound in your place is the same speaker that is lit up on the test program. I hope that helps, otherwise the amp is probably bad. Let me know if you need more help.
The Subwoofer is Likely Passive....meaning no amplifier is within the enclosure itself....the incompatible connectors mean you cannot connect the subwoofer itself to your surround sound system.
look for a Suitable stand-alone (1 Channel) Amplifer with sufficent power.....connect the RCA Imputs (subwoofer cable) to the Recievers RCA subwoofer output....then connect the amplifier's output to the the wire going into the subwoofer enclosure....if there is a plastic connector simply cut it off and strip the wires down a sufficent lenght....then secure the wires to the output of the amplifier.
if you do this make sure you know the ohm rating of the subwoofer and the minimum ohm rating of the amplifier your using.
Possible problems: 1) No output from the head unit. Try a different set of preamp outs. 2) No input to the amp. Check the RCA's and make sure that they are good and coming from a functioning preamp or subwoofer output on the head unit. 3) Input gain turned off or down too low. 4) Speaker wiring shorted, grounded, or open. Check all wires. 5) Speakers defective. Connect to a known good output to test. 6) The amp itself could be defective and still show a power-on indication.
Offhand, could either be the subwoofer speaker itself or the electronics (amp and/or crossover). One way to determine is by physcially checking the sub speaker. When playing with bass on, pls try restricting speaker movement by pressing on it and see if the noise is reduced. Another is to temporarily replace the speaker. You can try speakers meant for the car, home entertainment or book shelf, just dont set the volume too high.
If the speakers are ruled out, then it would be the electronics inside. For this, you would need familiairty with electronic components and circuittry, a DVM and a soldering iron. Access to an oscilloscope and an audio signal generator would be nice but not a necessity. The idea is to inject a constant audio signal and determine where the noise (if electronic) is coming from. In most instances, it would be a leaky electrolytic capacitor either in the input stage or feedback loop. At other times, it would be also a capacitor in the band pass filter.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
I have the same speaker and it sounds like its behaving properly.
if you look on the back of the amp, you will find a switch that allows the speaker to automatically switch the speaker on or off based on the level of the audio coming from the tuner that it is attached to. If the switch is set to the auto mode, then it will listen for audio on the line and if the signal level coming into the subwoofer is high enough, the amplifier in the subwoofer will turn on and play. If the signal is not strong or loud enough, then the subwoofer will not turn on. There are two solutions to getting the speaker to work.
1. When you turn on the tuner or audio source that is feeding the Subwoofer speaker, you will need to turn it up loud enough to trigger the circuit in the subwoofer to switch on.
2. Alternatively, you can bypass the automatic circuit and set it to the "ON position all the time. In this position the subwoofer is always ready and waiting and should play any signal that is fed to it regardless of the loudness or volume of sound from the tuner. The switch is located on the back of the speaker cabinet just to the right of the red and black speaker wire connections. It is labeled "AUTO" and the switch positions are labeled ON and OFF.
According to the KLH manual for the 9906 "6 pack" with the BassBite sub... it says "if your sub is connected via the speaker - level terminals, your reciever must be set for "NO" subwoofer - even though you are using one. VErify proper polarity on your speaker connection wires. (red or gold to +, black or silver to -). Depending on how you have your woofer connected to the reciever, if connected to a reciever without a subwoofer out then set your reciever for LARGE speakers and turn the subwoofer setting "OFF". Failure to do so will result in little to no bass. If you do have a subwoofer out from your reciever adjust your speaker size setting to small or large speakers as appropriate. Set the recievers sub output to ON. Connecting small speakers to a reciever set for LArge speakers can result in damage to small speakers.
