Samson DB500A Inside our rigid custom designed cabinet is a 15 inch driver designed exclusively for this project. Its matched with a new 1.75 inch Titanium high frequency driver, aimed through a 1 inch diameter horn. The dB500a features 500 watts of clean power (400 watts low frequency-100 watts high frequency) and has a crossover designed for high SPL. Our exclusive Optimax(TM) signal processing circuitry provides total speaker protection but wont cut the low end at high volumes, as similar speakers with sliding filters do. The back panel has a built-in mixer-like preamp section with mic and line inputs, XLR connectors and level controls. Controls for the selectable low pass filter and Optimax processing are also included. The dB500a speaker cabinet features an array of mounting options. Designed with floor monitoring in mind, they are also easily stacked or permanently installed. A 1 3-8 inch pole receptacle is built in, and 10 reinforced fly points are available.
