Does Pioneer carry any Tweeters which can replace and fit into my OEM tweeter location?

Yes, Pioneer has just introduced the Compact Super Tweeter TS-S20C which can be connected to the Amplifier directly. It has an external Filter which ensures only High frequency signals reach the super tweeters. It can be fitted directly into the OEM tweeter location, subject to the make of the vehicle. Kindly check with a Professional Car Audio Installer for fitment in your vehicle.
