 A15 focus is designed for medium range projection applications. As a member of the multifunctional A15 family, its passive 15 inch speaker has extremely flexible layout, strong ease of use and uncompromising speaker performance. Combined with the strictly controlled 10 ° coverage angle,

A15focs has an amazing 144db output and a projection distance of up to 45m. The hinge horn allows the user to adjust the directivity to cover the audience area of specific geometry and ensure excellent stability of frequency response. A15 focus and a15wide are OK

Hang or stack together to form a vertical line array. A single A15 focus can also be used as a point sound source with adjustable directivity for applications such as front area sound compensation or delayed sound compensation requiring narrow coverage. A15 focus can provide low frequency response at the level of large concert
