Binding Post on new Polk S35 Centre Channel Speaker Broke?

Hi all,

I've only had my S35 Channel Speaker for a couple of months and one of the speaker binding posts already snapped!

It seems that the speaker wire hole is drilled much too large and there is too little metal supporting the post, and hence it broke.

Is this common with Polk Speaker terminals - or at least the S-series?

    Call Polks CS....They should get you squared away.

    But....just for our sense of curiosity, maybe elaborate some on how this happened as it's not a normal occurrence for any brand.

    There is no inherent problem with the S series binding posts. Do you adhere to the "tighten until it turns freely, then tighten I/2 turn more" tightening process?

    I was using 14 gauge speaker wire. The speaker was taken out of the box for about a week, and only used for a couple hours for a test (still building my home theater).

    Yes, I didn't turn the post too hard - about 1/2 turn just to keep the speaker wire in place. When I permanently install the speaker, I'll be using banana terminals.

    I went to pack up the speaker yesterday night and found the negative terminal snapped clean.

    I've never had any speaker terminals break like this before hence my surprise.

    Perhaps it was a defect - I called Polk Support and they're sending me the whole crossover assembly - hopefully it won't be too difficult to replace.

    Yes, I called Polk Customer Service this morning and they're shipping me a replacement crossover unit. Hopefully I don't have to swap the whole unit to change out the binding post.

    I didn't over tighten either, I was using 14 gauge speaker wire to test the speaker in the interim while I finish up my basement renovations.

    I found the speaker terminal snapped clean when I went to pack it up yesterday night. No one else has been in the basement and the unit was unmoved.

    In anycase, when I permanently install the unit I'll be using Banana terminals - hopefully that will mitigate any future issues as well.
