How to Fix a Bose Cube Speaker
Bose speakers are well known as one of the best brands in audio equipment available. They have been touted to deliver sound that is as full and rich as though you were sitting in a concert hall. Sometimes, things can occur to cause problems with your Bose speakers. The cube speakers that come with the Acoustimass system are small but put out large amounts of sound. You can easily troubleshoot and fix minor problems with these cube speakers by following this guide. For problems that these steps do not fix, it is best to turn the speaker over to an expert to be fixed to prevent damage to these high-quality and expensive speakers.
Things You'll Need
- Acoustimass Bose cube speakersAmplifier or receiver which is the audio source (stereo tuner or CD player for example)
Turn off the audio input device or amplifier.
Disconnect and reconnect all the cables and wires going between the speakers and from the amplifier or sound source. Test your speakers to see if the problem is fixed. A faulty connection or a cable that is not plugged in properly are the most common causes of Bose speaker problems.
Turn the amplifier or sound source off again. To fix the left cube speaker, disconnect the both speaker cables that leads from the amplifier or sound source. Take the cable that leads from the LEFT INPUTS on the back of the bass speaker and connect it into the amplifier into the spot for the RIGHT SPEAKER. Turn the audio balance to the right on the amplifier (following the manufacturer's instructions for your amplifier or audio source). Listen to see if the left speaker is now working properly. If it is, the problem is in the output for the LEFT SPEAKER leading off the bass speaker.
Test the right speaker to hear if it is operating properly. If not, follow step three, but instead of reconnecting the cable from the LEFT INPUTS into the RIGHT SPEAKER, this time, you will reconnect the cable from the RIGHT INPUTS on the back of the bass speaker into the LEFT SPEAKER output from the amplifier. Test by adjusting the sound output balance on the amplifier to all the way to the left. If this has fixed the problem, there was a default with the RIGHT SPEAKER output channel.
Disconnect the entire system from the amplifier or audio input device if there is no sound. Reconnect the cables to another audio source. If this has fixed the problem, then there was a problem with the amplifier.
Take the cube speakers in for service if none of the steps above fixed the problem.
Tips & Warnings
- Do not attach the speakers directly to the audio input device or the amplifier. The speakers should only be connected to the back of the Acoustimass bass speaker (the large floor speaker). Once you find which output is not working, do not attach the other speaker to it. This could damage the speaker.
