CLASS BD - The Rockford Fosgate bd topology is more efficient than typical class AB and has lower distortion than class D designs. Rockford bd amplifiers are 75-80% efficient vs. 20-60% efficient class ab amplifiers. Delivering more power from your amplifier with less drain on your vehicles electrical and charging system.
CLASS AD - The Rockford Fosgate ad topology brings our high efficiency bd amplifier design to a full range application. Using our Dynamic Frequency Switching to increase the switching frequency during lower output levels for better signal resolution. Coupled with Post Choke Feedback Filtering to compare the input signal to the output signal at the speaker connector removing any unwanted distortion. These technologies eliminate the inherent switching
CLASS D - High efficiency amplifier design that reduces current consumption from the charging system
FULL RANGE CLASS D -High efficiency amplifier design that reduces current consumption from the charging system
CLASS TA - The trans•ana topology operates the output stage with its full voltage gain, which allows the input stage to operate from a low voltage regulated supply. The signal is then shifted up in level to the high voltage section by the driver stage which forms an active node at ultrasonic frequencies. This results in a very stable, highly linear operation.
CLASS BR - To achieve higher efficiency with lower distortion, Rockford's br topology combines, Cycle-by-Cycle, an indirectly coupled high/low voltage rail linear topology with a switched high/low voltage linear rail topology. This combination yields an unsurpassed power density (watts per cubic inch).
CLASS AB - The combination of a class B power output with the class A low distortion attributes make class AB the most common amplifier topology in the electronics industry.
Basket - Also referred to as the frame or chassis, this is the skeletal system of the speaker. Here to keep everything in its place.
Spider - Second part of the speakers suspension, connects the cone and voice coil to the basket and controls the travel of the cone assembly.
Voice Coil - The brains of the operation, directing the force from the magnet to push or pull based on the applied electrical signal.
Surround - First part in the speakers suspension, attached to the cone to maintain the centering of the voice coil in the magnetic gap.
Cone - A.K.A the diaphragm, this is the voice of the speaker. Shape and material dramatically change tonality.
Magnet - The heart of speaker, creating the force to push and pull cone assembly. Size, material, and design may differ, depending on performance goals.
Tweeter - Composed of the same parts as an speaker, surround, cone, voice coil, basket and magnet. Just on a smaller scale.
Crossover - Works like a switch board, directing the audio signal through caps, filters and switches to the appropriate speaker.
