Something Very Odd with my Polk S10s

[sjk88]

I just got a pair of used S10s and I noticed when they arrived there was something heavy sliding around in the bottom. I took the bass radiator off and there was a small magnet (too small to be the bass radiator's) lying loose in the cabinet. That was bad. But the worse part is the bass radiator did not have a magnet on it at all and it was not connected to the crossover. I checked the other speaker and it was the same way. The midrange and tweeter appear to be fine. Another odd thing is the crossover doesn't appear to have a wire torn off or missing. The only apparent connections are marked T+, T-, W+ and W- and these are connected the midrange and tweeter. The bass radiator is the SW1011 and the crossover is the RE 1005-1 and are marked as such. It looks like the bass radiator is a dummy, but I thought the S10s were 3-way speakers. What am I missing? What do I need to do to get this corrected?

The BASS RADIATOR is a *Passive Radiator* - IE: Not active, no magnet. It moves with the air flow of the cabinet...

I am guessing this is the speaker with a 7.5" midbass, and a 7.5" passive radiator right?

The S10 is a 2 way with a passive radiator...

The magnet probally fell off the midbass or something and is probally just a bucking cap...

Hehe.......damn those guys at Polk can't get anything right!

The "passive radiator" is 10 inches in diameter. The midrange is 7.5". Boy, was I worried when I saw the speaker not hooked up.

Check the other drivers for similarity, and perhaps a missing magnet. It is most likely a "bucking magnet", used for use near video sources, ala TV.

A Polk PR will not have a magnet...ever, it's passive. It has weights, not magnets.

The loose magnet was for the tweeter in that speaker. I set it back in place and by the way it looks it appears to be okay. Do I need to replace this tweeter or will everything be okay? I'm not looking for them to be perfect, just sound good enough for my general use stereo in my living room.

If you can hear the highs from that speaker, you'll be fine.

I agree, but will elaborate on NascarNut's :) reply.

A bucking magnet is typically fastened to the actual driver magnet structure. In other words, it's a leech...and mounted on the primary driver magnet structure. If your tweeter still has a magnet, and still produces sound, you should be 100%. If not, then get ready to but a replacement.
