Completely new to speakers. No sound coming from tweeters of lsi15's

I already have two lsi15's that sound absolutely great. But I bought another pair to add to my set up and I the tweeters aren't working on both speakers. If I hook up the speaker wires to the connectors at the bottom, the rest of the speaker sounds great as well as the subwoofer, but the tweeters aren't working, but If I connect the speaker wire to the top connectors, only the tweeter works with barely any sound coming out at all. The rest of the speaker doesn't work. I took a tweeter out of the pair that are working fine and it made no difference.

I disconnected all of the speakers from the receiver and tried them out one at a time.

Does anyone know what the problem may be?

    Not sure on that model can you try using jumpers OR speaker wire. Top to bottom on bindings - where your speaker wire / cable goes.. EDIT If you already use same speakers - are they the same where wire/cables hook in ? Maybe the metal tab / jumper is missing

    To expand, your original speakers have gold colored plate jumpers between the top and bottom binding posts. It appears those are missing from the pair you just purchased. You will need to make a pair of new jumpers by using short pieces of speaker cable.

    With the original speakers, I just connect the speaker wire to either the top or bottom connectors and they sound fine.

    So after I make a pair of jumpers, it will solve the problem?

    Do you have these on your new speakers? If not, you need to make some from speaker cable.

    Thanks for this. I just looked and I don't have them. Would you happen to have a link on where I can buy these?

    Well, they tend to vary in size/length depending on the binding post plate used, so finding the exact size you need would be a crap shoot. In reality, you are much better off using speaker cable as those gold plated brass plates leave a lot to be desired.

    Thanks. I took the jumper plates off the originals and now they sound great. I will give those in the link you provided a try.

    Thanks again!

    Ok, but sonically using speaker cable is better.
