B- 115 and B-215
Forsythe Series Bass
Horns
The EAW Forsythe series direct radiating low frequency
horns are designed for concert sound, theater
reinforcement and other applications requiring quality
reproduction with high output down to the 40 Hz region.
Construction is to the high standards for which EAW is
famous, using cross-grainlaminated birch with 18 plys to the
inch which has a much higher strength to weight ratio than
ordinary plywood or particle board found in other cabinets.
Extensive internal bracing virtually eliminates panel
resonances even at full concert sound levels. The true
exponential design allows better conversion efficiency and
pattern control over typical radial or quasi-exponential
designs. The finish is an advanced two component catalyzed
poly-urethane chemical coating that has exceptional scuff
resistance. Features include heavy-duty roadie corners,
protective speaker grills, integral speaker spacer plates, and
complete mounting hardware.
The 13- 115 is a direct rating bass horn for a single 15"
driver. It provides 8.5 dB of horn gain above 120 Hz and the
vent loading extends response down to 40 Hz.
The B-215 is a direct rating bass horn for two 15"
drivers. It provides 7.9 dB of horn gain above 100 Hz and
the vent loading extends response down to 40 Hz.
