The EVF-1122S-66-FGW from Bosch is a single 12" two-way 60° x 60° full-range fully-weatherized loudspeaker, white. The EVF-1122S-66-FG utilizes the ND2B, a high output 2" titanium compression driver, coupled to a Constant Directivity™ 60° x 60° waveguide. The SMX2121 12" woofer used FEA optimization for motor, suspension, and electrical design for very low distortion, high efficiency, and maximum intelligibility at high SPL levels. The crossover uses steep 24 dB/octave slopes with equalization for very smooth response in vocal range, linear off-axis response, and a protection circuit for long term reliability.
