Reflective Cross-Firing
In our ?“UpStage” system 500 series only the highest frequencies are handled by the cross-firing tweeters that are mounted up on the dashor a-pillars. These tweeters utilize the surface of the windshield to project a sound field of great clarity and transparency.Thel sound images can even appear to originate from beyond the windshield given good source material. On all source material, StageFront?technology ensures the apparent location of the sound source will not be associated with the position of the tweeters whether virtual or actual. This is a characteristic of any good speaker when properly set up.


Extra spaciousness and clarity in the sound can be achieved. StageFront? technology brings ideal “UpStage” imaging into any vehicle. ?


All Sound Above the Dash!
The CDT GOLD StageFront “UpStage” System, removes the distracting and low image sound effects from your conventional systems drivers and move your sound onto a seamless sound stage directly ahead up above the dash.

The CDT GOLD Upstage? System is available as a system to transform your vehicle. ?It includes a special set of frequency-control modules that can be combined with various speaker components that include tweeters, crossover modules, and mounting hardware.
The CDT GOLD Upstage? 500 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.
