1 Answer

Why did my all of my Bose surround sound speakers make a crackle sound then die?

One day my surround sound speakers, Bose, started to crackle, then they just died. All of them, at the same time. Do I have a problem with my speakers or is it my receiver, TX-NR609 Onkyo 7.2 home theater?

SOURCE: no surround sound

So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck

Make sure none of your speaker wires are touching. I had this problem. I re connected the wires. If a wire is touching the case it'll short out. It has a built in cut out.

I still have a crackling speaker on one channel but it doesn't cut out anymore.

NOOOOOOOOOOOOO!!! If you have the room for them to run free and loud, keep the 901's in service. Get them a good amplifier because any multichannel receiver can't deal with their special EQ needs and still drive conventional speakers for the other channels properly.

The good news. I have a setup similar to what I think you're trying to do and it works great! Get a receiver that has has 5.1 analog Outputs so you could drive up to 6 external amplifiers if you want to (I drive 4). Then you can draw off the Front L&R to a separate amp for the 901's and the 'other' (lesser) speakers can live on the receiver's native amplifiers.

A separate multi-channel amp for the 901's was my solution. Because I can run each channel independently to an external amp, I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers (DBX DB-SW 15's) and the Rear Surround channel (Bose 301), with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center (Kenwood 777's) and Surround speakers (Bose 301's) from its own amps.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Multi-CH Receiver L&R Audio Out ***) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.


Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Any modern AV Receiver with the pre-requisite analog outputs should work. Since you have to buy a power amp for your 901 front channels anyway the receiver need not be a powerhouse. Look for features and lots of connections for digital and analog devices. I lean toward coaxial digital connectors because A) they take standard >> and cheap << audio cables; and B) they can be shared with Y-connectors if you're careful to have only one digital device turned on at a time. Optical SP/DIF is an expensive farce to get into your wallet.

For DVD/Cable Box/Blu-Ray look for multiple HDMI or component connections. Again, length and cable cost made me look at the component connections vs HDMI and I was pleased that I can't see the difference even with HD programming from my cable box. It's all great.

SOURCE: I HAVE AN ONKYO TX

The symptom you described can be caused by any number of things. I always start with the output power transistors which are the first things to blow with a speaker output overload condition. Unplug the power cord to your unit, remove the top cover and use an ohmmeter to check resistance from C to E on all 10 of the power transistors (Q6050 thru 54 and Q6060 thru 64) attached to the large heat sink. Blown transistors typically read <1 ohm, compared to good transistors that are >10k ohms. If you find a bad transistor it will need to be replaced.

SOURCE: Rear surround speakers quit working from my Onkyo

It looks like the audio output was changed on the player so that it doesn't output 5.1. Enter the setup menu on the player and change DTS to output DTS instead of what be labled as stereo or L/R and Dolby Digital to output Dolby Digital instead of whatever else it is set to.

Not good surround sound Is the bose lifestyle 5 support 5.1 surround sound?


The Bose Lifestyle 5 is not a 5.1 surround sound system. It is a 2.1 sound system, meaning it is stereo with a subwoofer/bass unit. Having two speakers that can be angled in different directions, the Bose Lifestyle 5 employs Bose direct/reflecting technology,providing greater audio presence. Still, it is definitely not a surround sound system.

Recently, I purchased a used set of Bose 901 VI speakers. They are crackling when base sounds play. What is the problem? Was I duped? Is it the speakers or the amp or the volume. Can I repair?


It is likely that the speakers were damaged by someone playing the system at way too high a level.

If the noise sounds like a scraping, then it is the speakers themselves.
If the noise sounds like a breaking sound then it is likely the amplifier.

Another possibility is that if you are not useing a Bose amplifier, then your amp may not be capable of properly powering the speakers.

Crackling sound


That sounds like an internal fault on your Bose system.

Leave the Bose unplugged from power and from computer for one hour, to get rid of electrostatic charges accumulated inside capacitors.
If that does not get rid of the problem, then there is an internal fault, either a short on speaker wiring, or a fault on the internal amp circuit board.

Crackling and popping sounds in surround sound speakers


Could be your head unit or the connection to the speaker may be bad. Also if the wire to the speakers in your ceiling is bare and touching any ground it would interfere. Start by checking connections by playing something and messing with wires. Listen for a difference. Next check by putting the wires that power those speakers in a known working output and listen for different quality

Bose amplifier does not work with a 6 speaker selector


your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
