    Default Lsi9 left speaker problem.

    I bought these speakers a year ago. I've noticed for a while now that the left speaker is not as bright as the right speaker. The output from the tweeter is nonexistant compared to the right. I'm missing much of the mid/highs from the left speaker.

    I swapped tweeters between speakers and the problem stayed with the left speaker. I also swapped left and right cables to make sure it wasn't my emotiva xpa-3 amp or yamaha rx-v663 receiver. The problem stayed with the left speaker. Am I correct that it must be the crossover? TIA

    Could be a problem also with the amp or receivers left channel. Did you try just hooking up the left speaker to the right channel ?

    try another amp to rule out an amp problem, if it is not the amp, it is the crossover of the speaker (not sending high frequencies to the tweet)

    I would wager a guess it is the crossover (call Polk and see what they can do) but swap the amp just to rule that out first

    Thanks. I did some more testing. I've got the left speaker playing out of the right channel of the amp and also the right channel of the yamaha receiver. Still the same result...very little output through the left tweeter. There's definitely a big difference in sound among the left and right speakers. It must be the crossover.

    If its under warranty, Polk will replace it. Hope you have your receipt & you are the original buyer because it helps. It does sound like the x-over though.
