Eminence SD28: 1″ Dome 4 ohm Tweeter
*Good replacement for many Polk Audio tweeters that are discontinued. Some modification is needed. You will need to remove the bad tweeter from the face plate (acetone will help soften up the glue) and mount this tweeter on the original Polk face plate.
The Eminence SD28 soft-dome tweeter offers unmatched performance to value in an ultra-compact design. With an overall diameter of less than 1.5 inches, this 4 ohm silk dome tweeter delivers smooth high frequency reproduction from 1.5 to 20 kHz. Perfect for home audio, car audio, ATV, RV, or any other application where space is limited.
