KH7
describe
The Firenze-KH7 is an extremely compact speaker with a high power density in an elegant frame. The self-powered line array unit features four 12-inch coaxial neodymium magnet woofers that produce an exceptional peak output of 141 dB SPL for powerful, even coverage in the venue. An integrated Class D amplifier provides 4 x 2000 W at 4Ω. The Firenze-KH7 has an adjustable 100° x 30° horn for a choice of wide or narrow sound launch, as well as a variety of dedicated connection and suspension accessories for different configurations, including vertical and horizontal cluster arrays.
