This set use the smoothest silk Tweeter you ever heard. Always gentle and forgiving, this Tweeter emphasizes the music and avoids noise and artifacts that may embed some source material or be characteristic of less than perfect amplifiers. Perfect for use up on the dash or A-pillars.
Very low listening fatigue and an easy quality that puts an emphasis on the system's midrange. The driver is a 3/4" silk dome cooled by ferrofluid
Neodymium magnet including surface and flush mounts.
The Upstage 500XT series add-on module in the system is a specific blending band-control module to set up the "cross-firing" windshield tweeters. This blending module also shape and filters the signals going to the door speakers to maintain non-varying controlled dispersion. On-board jumpers set up various types of door speakers. Level-matching options are also provided to set up the tweeters and perfect frequency tuning of the door speakers. A set of these tweeters and various mounting options completes the primary front system.

Nothing Ripped Out Or Thrown Out!
One of the best things about the Upstage system is that none of your speakers, none of your crossovers, not one part of your system whatsoever needs to be ripped out or thrown out. The UpStage 500 system is an addition that improves and enhances what you already have.
Adding those two super tweeters (plus the addition of specially engineered shaping and blending modules you cannot see) will make you see the light... will make you see the future of more accurate, more realistic, and more exciting sound reproduction... and the future of music on the road
