Hi all, I have a pair of LS70 or LS50s... I guess I need to figure that out first. I've noticed a slight distortion coming from one of the drivers. You can see that one of these drivers was probably already replaced as the 'dome' section is smooth unlike the original drivers that have the raised design (both of the drivers on the right speaker have the raised design as well).

TBH, I don't remember if is' the replacement driver or the original that has problems as it's been a few weeks since I checked it.

Anyways, can anyone tell me what specific driver I'm looking for to match the originals? Thanks!

    Update: I should read my own past posts. These are LS50s - 6.5" driver. Anyone have a replacement and/or know the driver model I need?

    Call CS, they have them. 800-377-7655. Tell them you're a forum member for a discount and free shipping. Last one I bought was like $48 IIRC

    I was never into the newer models of the Polk lines. Can't help there but why are there 2 different dust cover designs ? I found these in central Jersey C/L and still can't tell if the d/c are changed out. The LS50s or LS70s

    is the dust cover and dust cap the same thing? IE. The oval dome in the middle of the driver?

    I'm not the original owner so I'm not sure if the previous owner replaced one of the drivers or if it came like that from the factory. Seems like they'd all match from factory since they were all installed at the same time, even if the dust cap changed in future iterations of the same model driver

    The one without the embossed dust cap is a replacement.
