 Class-BR
Stores energy and dynamically boosts rail voltage to create power on demand.
To achieve higher efficiency with lower distortion, Rockford Fosgate's BR topology combines, cycle-by-cycle, an indirectly coupled high/low voltage rail linear topology. This combination yields an unsurpassed power density (watts per cubic inch).

 DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
DSM - An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.
MEHSA3
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
