Diagnosing speakers

Jun 04, 2020 16 Replies

I have a 6 speaker home theater system.



However the middle 2 speakers have no sound.



I checked the voltages.


0 volts when a movie is playing versus .22 Vdc when movie is not playing.

Does that help at all?



Thanks, Andy


Actually the answer you got was correct.

If you just give a vague question it would not behoove you to get upset when replies are terse. The description you gave doesn't say much at all. Are they powered speakers, wireless ?? etc. etc.

The speakers are attached to a radio/DVD system.

Andy is into "minimalism". This includes his I.Q.

You are a real big man.

You must have lots of friends.

Maybe the movie you have has no surround sound recorded.

Jasen.

NO. Not really. I might even be considered a dwarf. and by no means, the youngest of seven, unlike you. You have been told in (3) various ways to provide more information about what (and how) you have these speakers configured / connected / being measured and under what conditions. In spite of that you are NOT getting the hint and especially, NOT providing further info. If you expect to get a spoon-fed response with a ready-made answer, YOU will have to do some work beyond simply typing single line questions. Get over your "specialness"

Actually yes. I bet you do too.

** LOL - that is way too subtle.

Why don't you supply us with the brand name and model number of the speakers? Of the whole system as a matter of fact. That would be a big help. And did you measure the voltage at the source? And why did you use DC? Speakers run an AC. And no, what you posted didn't really help. Eric

I thought that the radio would simulate the surround sound if there was none?

It also occurs with other movies.

Andy

Give us the make and model number. Do you have the manual?

I'm presuming these are the rear surround pair.

Means nothing, except charitably maybe that at least the speakers are connected to something and not floating around in the wind.

(If you had properly wanted to test the speakers are connected, a better check would have been to disconnect each in turn from the amplifier and with your meter do a resistance check across the leads. It should measure whatever ohm figure is printed on the back of the speaker.)

Some surround systems have a test mode, to make a small noise from each speaker, one at a time. Have you tried this?

There are many surround encoding schemes depending on source. And special effects from your amplifier, and yeah maybe simulating rear surround - how are we to know you have correctly turned that function on?

The comments posted by other respondents are entirely valid. You have to help people to answer you, not imagine they are mind readers. Give useful information - make/model is a good clue, and go find that manual!

Those speakers do work when listening to the radio.

So, I know the speakers are o.k.

Andy

Thanks so much.

The test mode is what I needed.

It sent test tones to each of the 3 pairs of speakers.

Manual said to adjust the volume to be the same.

I had to have my ear close to the speakers to gauge how much to change the volume.
