I've blown something - haven't I?

[louisk]

Please forgive me if this is an old and boring question but I'm really stuck and I'm not sure if the problem is me or the equipment.

My main speakers are B&W DM602-S3s and the sound between the amp and the speakers has been absolutely perfect.

So perfect in fact that i tried to improve everything by attaching a set of Wharfedale Diamond 8.1 speakers as the "B" speakers so i could hear the system in another room.


Trouble is - and i really have checked all the connecting cables here - that all i get from the second set of speakers is very muted information through the left hand speaker, and absolutely nothing through the right.


Could this be an impedance issue? The Wharfedales are rated at 6ohms though the brochure also states they're suitable for 8 ohm amplifier outputs.


I've tried disconnecting the B&W speakers and wiring the Wharfedales to the
"A" speakers channel, same result, The left speaker tinny and bassless, the right one dead.Yet one week ago, these Wharfedales were my main speakers and performed flawlessly.
I've blown something within the Wharfedale speakers by wiring them up as the secondary pair, haven't I?
Is there any repair for this or have i just killed a perfectly good set of speakers?

Any info or explanation very gratefully welcomed.
Thank you all very much

Seems to me,that you may have to press a swith somewhere,I think you've at the moment,got your amp on speakers A only,try to put on speakers A&B,then see what.Finally just try speakers B and see if you get sound sound from the Wharfdales.Maybe the amp,also doesn't like to run 4 speakers at once,what the amp?stereo or A/V?

I thought I'd mentioned the amp - obviously i didn't. It's a Rotel RA-02. The amp claims it can run two sets of speakers at one time as long as the impedence of both is 8 ohms or greater which is why I'm wondering if that's where the problem lies.
The B&W speakers work on both A and B channels. The Wharfedale now work on neither.

Thanks for your input

The Wharfedale now work on neither.

Great,there's your problem.

Hi louisk - yes - if your B&W's work fine on either A or B, and the Wharfedale's don't work on either, then that obv points to the Wharfedale's.

But I hardly think you'll have blown them by setting them up as a secondary - where'd they come from ? New/2nd hand ? Have they ever worked ?

Check the polarity of the wiring. Maybe you lost track of the +/- through to the other room.
