THERMAL MASS PER INCHThese amplifier cross sections show the amount of heatsink material (Thermal Mass). A greater thermal mass means increased play time and lower device distortion.
TOPOLOGIES EXPLAINEDAmplifier topology is the arrangement of parts in an amplifier design. These designs are broken out into 'classes'. Each class has tradeoffs, making the various classes suited for various applications…like Class D or BD with higher RMS power, but undesirable noise in the higher frequencies making it better suited to power subwoofers.
  • 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.

Subwoofer SPL Glossary IconSPL - Sound Pressure Level numbers reflect an incar response utilizing dual subwoofers in a typical sedan size cabin at peak power.
Subwoofer XMAX Glossary IconXMAX - The measured excursion of the subwoofer in one direction, with Peak-to-Peak covering its entiretravel. The more air a woofer moves the higher the SPL.
Subwoofer Peak Power Glossary IconPEAK POWER - The maximum amount of amplifier power that can be applied to a subwoofer prior to entering into an unsafe operating scenario.
ANATOMY OF A SUBWOOFERVariations in the anatomy of a subwoofer dramatically changes their performance characteristics. An increase in voicecoil size coupled with a stronger cone material yields a higher power handling and increased output. By combining quality materials with Rockford’s proprietary acoustic technologies, our subwoofer lineup is sure to meet your system’s demands.
