Tweeter: DRT-25 "Extended Range"  1" silk tweeter The new engineering "Extended Range" design opens up the system mid-high transients and upper energy response to a degree you never heard before. The "extended range" tweeter ships with housing cups including: Surface flat,  Surface angle,  Flush and Flush angle. If your budget does not allow for the high-end "StageFront UpStage" System 500 series: There is a good reason to add a pair of image enhancement tweeters upfront connected to an attenuator which is to improve the distribution of the highs and to fuse those highs into the overall sound. This image enhancement system will bring the highs and stereo image sound stage level to where the drivers head sits. No more playing for your legs.  Many auto-sound systems cannot ideally provide for a convenient ideal mounting position. In some cases the tweeters may need to be mounted well below ear level. In order to embellish the extreme top end and to lift the image (usually toward the windshield area) the Image Enhancement kit can do the job.
