The Delta 15 from Denon is a 15" 2-way loudspeaker featuring wireless connectivity, an integrated 2400W Class-D amplifier, and ultra-durable, linear transducers that are paired with custom DSP-controlled crossovers. The high frequency driver utilizes a computer-designed waveguide for an optimized 90° x 60° coverage field. The Delta 15 offers clear and natural sound reproduction with full bass and smooth highs.
Additionally, the Delta 15 provides wireless connectivity via Bluetooth, which offers control over internal digital signal processing (DSP), giving operators powerful sound-shaping capabilities in the field and away from the mix position. The free iOS app, Live Drive, offers wireless control of time-compensation, EQ curves, gain, test tones, and more. The Delta 15 ships with a standard IEC power cord.
