I hooked up Energy classic 5.1 speakers to pioneer vsx 1121 k about an year ago. They were working fine until few days back. Suddenly the receiver started switching off beyond a certain volume level (which was not at all loud). I then used Automatic MCACC to calibrate the system, during which I found out the speaker that was causing the issue. Now Im not sure what needs be done next. Is there a way to fix that speaker ??

First you'd have to find the short (assuming that's what it is). Did you at least make sure your speaker cables are in good order? Is it one particular speaker? Can you think of any changes made or events that coincide with the problem? You need to provide more information....

Short answer, maybe.

It is one particular speaker. First i thought there was a short, but when i moved speaker position from left to right the problem also moved.

Since the front speakers in that system are way too small, you could make a huge improvement by buying a Pair of Polk Monitor 30 speakers and using them as your fronts. That will cost less than $100.

If you want to stay with Energy, Amazon has a pair of C-50 speakers for sale for $110. Those would work.

Either way would be a nice system upgrade.

I would love to upgrade but before that need to find out what happened with that one speaker. Since it was working fine for almost an year. What could be the various reasons that could affect that one speaker? Is there a way to check and ifx ?

Thanks smile.gif .

A driver failure or crossover component failure could cause an impedance dip that overloads the amp, causing the shutdown. This can be easily traced by someone with the requisite tools and skills, but the cost could exceed the replacement value of the speaker.

Those speakers come with a 5 year warranty. Send it in for repair...

Disconnect all the speakers from the receiver and try each speaker ,it could be a bad speaker cable.if you bough then from a authorized dealer you can send then for repair, but fist make sure which speaker is causing the problem also you can try resetting the receiver.


make sure that a positive cable is not touching the metal back panel of the receiver.

Panasonic 65VT60 / Marantz SR7005 / Marantz UD7007 /PSA XS30 /Revel Performa3 F206 / Revel Performa3 C205 / Sonos Connect/ Roku 3 / Amazon Fire tv / Xbox One / HTPC / Darbee 5000 /Sonos system for rooms/
