LSi7 Right Speaker Underpowered and making popping noises

Hi all,

I purchased a pair of LSi7 bookshelf speakers and they've worked great for a few months.

I recently picked up a Onkyo TX-NR515 receiver and after rewiring everything I've noticed that my right speaker is now very underpowered when compared to the left is also very tinny sounding and making popping noises.

I plugged it into the left channel on the receiver and it's still doing the same thing. I tried use different wire, but still getting the same problem.

Not sure if there is something I'm doing wrong, but I can't imagine that the speaker is blown being that I've never 'blasted' them. Hoping there is something obvious that I'm not thinking about. Any suggestions would be appreciated.

Thank you.

    I think you may be over stressing you avr. The LSI series speakers are 4 ohm speakers, while the LSIM are the 8 ohm series. According to Onkyo your avr isn't designed got 4 ohm speakers.

    Damn. Anything I can do other than buying a new receiver? Is it possible that I ruined the speaker?

    Just swap the speakers and see if the one sounds the same on the other side.

    Also he should be able to grab a new amp to power those speakers like a Emotiva XPA-2,3 or 5 as long as the receiver he has now has pre-outs. Those would drive 4 ohm speakers.

    Find a good used one to save some dough as long as it still has the warranty. Theres some on ebay.

    The same speaker produces that noise or the same channel?

    Tried the one speaker alone? If its still doing it alone then i'd say the speaker is now bad. Wait for a better opinion though...

    Can I run an amp through the receiver through a subwoofer pre-out? There are two on the back of this receiver.

    No, you can not use the sub out as a pre out. Your AVR has no pre outs. If you continue to run 4 ohm speakers on equipment designe for higher impedance speakers, on of 3 things will happen:

    1) you destroy speakers and/or cross overs

    2) you do serious damage to your AVR amp section-usually terminal

    3) Both 1 and 2

    What were you using for power before buying the AVR?
