Silver Coil Dome - How ID Model & Remove from Wall
PA_User
Posts: 1
Hello,
I purchased a residence built in the mid-1990's that has Polk Audio built-in wall speaker pairs in 6 rooms with 12AWG 4-channel cables running to a stereo cabinet in which the components have been removed. [There is also a second in-tact stereo system in another cabinet, which has 4 of the same speakers hard wired that works well.]
I want to replace the removed stereo components, but I would first like to remove the 12 speakers to confirm the precise models, ohms specs, and wire color coding to each pair. The 12-4 cable from each room's speaker pairs into the control room have these 4 colors: Red-darker, Red-lighter, white and tan. I have identified the rooms for each 12-4 cable, but the 4 individual wires are not labeled. Any guesses how the L+, L-, R+, R- wiring sequence would typically be done with this cable color coding?
Using the manual for the similar appearing current RC55i speakers, I was able to remove the grill, which revealed this marking: “Polk Audio Silver Coil Dome”, which I understand is consistent with the mid-1990's. The size of this speaker frame is 7”W x 16.5”H. Can anyone identify the precise model from this info? Is there a manual available for Silver Coil Dome speakers?
The RC55i manual, which did not address how to remove an installed speaker, says on page 8 to loosen the rotating wall clamps, turn them inwards and tighten to rotate the clamps behind the drywall. So I loosened the 8 screws that are around the edge inside the frame. I could hear what sounded like most of the clamps rotating down, but the speaker appears to be stuck at a couple of points. I am not sure if turning the screws too many turns will let the clips drop into the wall, so I stopped to get some advice from those who know this model. Any tips, thoughts or suggestions on how to remove these speaker? Is there a photo of the rear of this type of speaker available?
Thanks for any advice.

Is this what your tweeter looks like?
There's no manual for any Polk tweeter.

Sounds similar to John's experience with the AB800. I didn't even remember there was such a thing with the SL2000 tweeters.
