30 - 3200 Hertz useable range (-10dB)
100° horizontal X 100° vertical at 1000 Hertz
126.5dB SPL calculated peak, 1 meter, half space, at rated rms power with 6 dB crest factor pink noise input, 35 - 1000 Hertz.
120.5dBA SPL calculated maximum continuous, 1 meter. The dBA scale is typically used to identify sound sources
which can cause permanent hearing loss.
