U.S. Patent US 8,212,620 B2
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).
U.S. Patent 3,883,832
Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.
In the early 70’s, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars:
- A midbass hump between 100-275Hz
- A steep roll-off of high frequencies from 2kHz up to 20kHz
- Reduced bass response below 50Hz
The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.
