Soundstream Technologies EXC.4 - Manual (Page 3)

The EXC Component Speaker System is the result of highly focused engineering effort.
Each element of the EXC system represents several advances in automotive speaker
technology. When the EXC project was initiated, the following goals were established:
• High performance sound reproduction in the automotive environment.
• Ease of installation
• Superb ergonomics and visual appeal.
• High output capability
• Ability to "tailor" sound to each vehicle
Through extensive testing and development, the EXC system has been designed to
provide extremely consistent on and off-axis response in the automobile. Installation
flexibility and ergonomics are enhanced by the mounting versatility of both the EXC
midrange/woofer and the EXC tweeter. Finally, the high output capability and low
frequency extension of the EXC woofers are atypical of most drivers due to the
excursion capabilities of the EXC woofers and the steep crossover slopes of the EXC
system crossovers.
These efforts have resulted in an extremely flexible speaker system that performs
flawlessly in a variety of locations.

DESIGN
FEATURES
EXC Midrange / Woofer
The EXC woofers represent a departure from typical midrange/mid-bass drivers by
combining massive mid-bass and exceptionally smooth midrange.
• Non-resonant Glass resin basket has been designed specifically for extra long
excursion. This results in higher output and extended low frequency response.
• Non-resonant cone geometry yields smooth response and ultra-low distortion.
EXC Soft Dome Neodymium Tweeter
The EXC tweeter is an ultra-high performance 1" Neodymium tweeter designed to
deliver outstanding high frequency reproduction
• Fourth-generation Neodymium Magnetic Assembly providing performance comparable or
superior to tweeters three times the size
• A newly improved Textile Dome for a natural, smooth response to 20 kHz.
• Ferrofluid-immersed Voice Coil enhances heat dissipation
EXC Passive Crossover Network
The EXC Passive Crossover represents a new concept in crossover philosophy. The
EXC system crossover consists of high quality, multi-element components with two
switchable functions. A three-position switch controls the tweeter level and a two-
position switch controls the midrange presence. The combination of each allows for a
multitude of control options. Dual inputs allow for multi-channel amp operation of woofer
and tweeter circuits.
• 24 dB/octave Acoustic Summation Crossover Slopes for smooth response.
• Variable Tweeter and Midrange Controls for added flexibility.
• Dual Inputs for multi-amp operation and further flexibility.
• Dynamic Tweeter level Control allows for improved power handling and continuous output.
• Ultra-low DCR Inductors for minimal signal loss (High power Air-core type in woofer path).
• Mylar Film Capacitors to ensure low saturation and accuracy in the high frequencies.
