Does the subwoofer have the same hum when the input cables have been unplugged? Many input cables use very fine conductors, which often fail. A bad cable will often introduce a hum and prevent a signal from getting through. If the noise is still present without the input cable(s) connected, then repair options are limited. No schematics are available. There's a daughterboard that has been available, but its failure usually causes the system to die (short-circuit). The cost to repair the amplifier may be close to the cost to replace the entire sub.
Disconnect the sub-woofer and see if the noise stops, if so the amplifier is OSCILLATING and so produces the noise.This can be related to fault with the pre-amp or audio processing section. Try and heat up the circuit using a hair dryer and if the fault clears then there are faulty electronic capacitors. If leak is seen then the pcb must be washed after the capacitor is replaced which can solve the issue.
Hi,sorry but you can not connect it directly like other sub-woofers.. Bose 2683 Powered Subwoofer is part of Bose Lifestyle 5 system, Please note that
you will need the 5-pin DIN cable that connects the subwoofer to the
base or "Music Center". and the 4 pronged connections for its own stereo speaker output not input from another stereo.. Sorry....but if you can arrange some handy man nearby ,he may get into the DIN cable to locate the subwoofer signal 2x input leads than you can use that leads for connecting into single sub woofer out let of your system...otherwise try to sell BOSE which can easily buy brand new up to date powered sub.. . Take care and please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps!
You need to make sure everything is wired properly, make sure the device your playing the music off of has the capacity of 130 watts of sound, and check to make sure your system is set to play that woofer.
sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty
damaged sub woofer eg.
Thanks for rating
It is a 4 ohm nominal impedance woofer. If you put a new woofer in, it will last maybe half an hour and then fry/melt. The problem is the amp, not the woofer. Throw the amp out and use the box as a passive sub. Get a 100 hz sub crossover.
firt you clean the subwoofer with cleaner after that, check the subwoofer srrounding, no electrical wire ,mobile phone & electrical operated items is near ur subwoofer.
1. Do not use maximum volume of subwoofer.
2. Use only 65-85% volume of your sub woofer.
Your subwoofer is not capable of playing as loud as you want it to. That sound is the woofer reaching its limit. If you have any bass tone setting on your receiver set them to flat. If there are any other bass settings i.e contour, loudness boost etc turn them off.
You can also try putting the woofer into a corner. This will increase the output. Closer to you would also be louder. Otherwise you need a sub with more output. Don't let the power rating fool you when you get a new one.
This means that you have purchased a three piece home theatre system. Two tweeters and a sub-woofer. Assuming you are using a Stereo player (Tape/CD/DVC)you have to connect the Left Output of the Stereo placer to the Left Input at the back of the Sub-Woofer and the Right output to the Right input of the subwoofer by cables. Then take tweeters and connect them to Right speaker and Left speaker output at the back of the sub-woofer ( note if the speakers are marked L/R, then connect them to the subwoofer output accordingly. In case you are using a 5.1 player, then only connect the front right and front left to the Right and Left input at the back of the subwoofer. You are and you can now start playing your music or movies and and you will get theatre quality sound.
