Description The eXcelon Reference Fit amplifiers will satisfy the discerning mobile audiophile with its simple
design and unyielding power.
These amplifiers are built to be easily installed in the tightest applications yet they provide the
power required to pump out the sound you want to hear.
Class D Amplifier
- For subwoofer applications, Class D amps are beautifully efficient and their small size offers
installation flexibility.
Dual Sigma Drive
- This advanced negative feed back circuit improves damping factor and increases accuracy and
sound quality. When a signal is passed to a subwoofer, like a 50Hz note, the speaker will move
and create the note. However, because the speaker has mass and a suspension, it won’t stop
moving once it’s in motion. This extra movement (sound) creates a type of distortion that’s not
part of the original signal. The negative feedback circuit senses this unwanted movement and
send out an opposite pulse to stop the speaker like an electronic brake.
