Smoked Speakers.... Please help (1 Viewer)

[Murraugh]

Good morning.
I purchased a Sherwood RX-4109 105 Watt Stereo Receiver and two pairs of Yamaha NS-AW150BL speakers.
I assumed that the having speakers rated at 120 Watt and a receiver rated at 105 Watt would work pretty well. Well i was running both sets of speakers and one of them started smoking. The other pair seems fine. Any idea what has gone awry?
Thanks.

Ok, since this is an outdoor speaker...were these being used outside?
IF so, I bet you drove the receiver right into clipping.
But, that is only an assumption since you don't give any details.

It is an outdoor speaker. I am using it in a room that has a tendency to leak, and we wanted to have something that could handle a little moisture. That being said...It was not exposed to any moisture or weather.
I would be more than happy to give additional details, but I am not sure exactly what you would need....
What do you mean by "drove the receiver right into clipping"?

Welcome to the forum Doug. This receiver will only drive two speakers at any one time, were you driving all four at the same time? If so this could damage the receiver. Otherwise it just sounds like your speaker went bad.

Like said above...
How exactly are these connected?
How loud were you listening?
What source was being used?

Ok. I have been reading up on it more. I'm afraid that i am about to learn a lesson the hard way.
The manual for the receiver says that i can run all 4 speakers at the same time if they they are speakers with am impedance of over 16Ω.
The Yamaha speaker has 6Ω impedance.
How can i tell if i have damaged my receiver?

 

[Murraugh]

They are connected with 14/2 Speaker wire. Nothing special. Came in a 250 foot roll from Home Depot.
I was using it at about 3/4 volume. It is in a dance studio, so it gets VERY regular use.
The source was a Sony CD Changer.

You can check receiver damage by connecting a speaker, you know works, to each output of the receiver.

So basically if i get clean sound, the receiver is OK?
Do you have any recommendations for a ceiling speaker with an impedance of over 16Ω?
Thanks.

Return(if you still can) that Sherwood. It has a heinous amount of distortion.
If all you are using is a cd player, buy a used stereo receiver or integrated amp(means it doesn't have AM/FM).
Methinks the problem is you are asking for more than this Sherwood can deliver.
This is much closer to what you need. And don't let the "it has less watts" fool you...

Can that Karmen Harden be used to run all 4 of my existing Yamaha speakers? I didn't see anything in the Manual about the impedance or power of the speakers when running 4 at once.
