QLB 215

The high power, universal bass system QLB 215 with exceptional sound quality comes with optimized transport dimensions for truck and transporter. Inside, two newly developed 15“ long excursion speakers work in a hybrid arrangement ensuring small dimensions remaining low cutoff frequency and minimizes airflow noise especially at low frequencies. The QLB 215 can be used together with either Line Array systems or other top units. Using suitable amplifiers (i.e. DA 230) the customer can construct directional bass arrays with more units. Two Speakon sockets on the back side and one socket in the front grid ensure easy cabling for all chosen using modes. An option for wheel mounting is also available on the back side.
