Polk sda 2.3 help

chandler9a

Hello all, I am new to the forum but I really like all that I have read about the SDA line. My Father has had his sda 2.3's ever since I was a young boy and lately I've noticed that the two middle drivers on the outside of the right channel speaker are not moving as they should when music is played (these are the 2.3's with the donuts on the top and bottom outside woofers). I realize the sda affect and don't think that is the issue. the same woofers on the left channel speaker are moving differently and fine. I don't know if the right channel ones are blown or what the problem might be. Any thoughts would be great, I want these babies to run as they should. thanks

If you gently press on the passive radiator (big sucker down at the bottom), do the drivers move in and out opposite of how you're moving the radiator? If not, they may be locked up, which will necessitate replacement.

If they move, you could just have a loose wire? Have these speakers ever been physically moved/jarred around? That's the usual suspect with frozen drivers.

thank you for the help, I checked and everything seems to be intact. I will do some more testing and hopefully figure out the problem if there is one at all. these have been moved all over the world... U.S. - Japan- and back so there could be other wires loose inside. they still sound amazing however.
I've seen pictures of these online but reversed ( left and right on opposite sides), we have the 4 woofers on outside of each speaker like it implies but I'm just making sure.
