I have a pair of bose 802 series 2s. However one of the speakers is not working to its full capacity and will only play music very quietly if it is turned up it becomes very distorted. Does this mean the speaker is blown or is it something to do with the leads/amp set up?

Hi jam123 and welcome to DJU.

The Bose 802 is made up of 8 speakers internally and I would of thought it unlikely (but possible) to blow all of them.

First I would swap leads and amp channels to see if the problem persists. What power is the amp you are using (rms watts at 8 ohms)? Are you using them with the Bose controller?

Ive tryed swapping the leads earlier and I am using the bose controller. I am using an old peavy amp deca 1200 i believe its output is 4 ohms. Only one channel works on the amp so im using both the out puts on that one channel for both speakers. However i had the speakers working perfectly earlier but then when i turned them back on the amp started cutting out and i had the same problems as before, I couldnt play the music loud enough without the amp cutting out. I dont understand how they can be working perfectly one moment not working at all?

Next thing to check is if the amplifier is the problem. You have already mentioned that one channel doesn't work so it could be possible that the other channel is going too.. I believe the Peavey Decca was an early foray by Peavey into digital amps and are not as robust as todays amps.

Have you got another amp to test the speakers with?

no i believe i am stuffed. I think im gunna have to buy some new ones. Do u have any reccomendations that are fairly cheap. Are intimidations any good for starters?

And what was the result?

Jim

It's always possible that one driver has gone short and is pulling the amp down. What damaged it last time?

I have decided to buy some new speakers, However i was told that new speakers must be "WARMED UP" Is there a specific way to do this or is it just rubbish?

just buying new speakers worries me... you still dont have the amp problem sorted.. you could end up killing your nice new speakers dead...

as for warming them up.... i think you mean runing them in.. in the high fi world its advisable to run your new speakers for a couple of days at low volume so that they get a good work out... losen up and then when you listen to them in future the sound will be the same all the time.. new speakers sound different to used ones...

but the difference is slight.. so im not sure your going to notice the difference on a set of disco speakers from new to used... plus with a bad amp and low bitrate music we are not talking hifi are we...

I have a new amp as well so it's all good the old ones are gone so a new life. One more qestion when sending the signal from my mixer to the amp should the vu levels be just going into the red or not going into the red at all?

What have you done with the 802's?

Jim

The odd foray into red shouldn't hurt, but I try to err on the side of caution and would try to keep the level below the red at the upper yellow.

My rule is amps always up full control levels from mixer avoid going into the red on mixer as you will be putting out a distorted signal avoid going into the red on the amps as clipping will occur
