10-INCH 2-WAY 2400-WATT LOUDSPEAKER WITH WIRELESS CONNECTIVITY For situations that demand the ultimate in speaker performance, Denon Professional proudly offers the Delta Series—a family of powered loudspeakers that delivers the very highest level of acoustic performance, essential for critical musical productions, dynamic AV playback and clear, articulate spoken presentations. The Delta Series was designed from a clean sheet of paper to exacting performance standards, using custom-developed, purpose-matched components. The Delta 10 features an integral low-distortion Class D amplifier capable of 2400 watts peak (1200 watts continuous) output, rugged, linear transducers, DSP-controlled custom crossovers, EQ contour switch and a computer-designed high-frequency waveguide for an optimized 90° x 60° coverage field and extremely flexible connection/control facilities for adapting to any usage condition. Plus, it utilizes dynamic thermal protection, to ensure crystal-clear sound reproduction at any volume level. However, it’s not the printed specifications or the number of inputs and outputs that qualifies the Delta 10 as such an elite performer. It’s the performance. The sound is effortless, clear and natural. There is no sense of strain or coloration. With lesser speakers, the listener can immediately hear the “reproduced” nature of the sound; that unmistakable nasal artificiality and edgy, strident distortion that betrays the sound of an inaccurate speaker system. When you hear the Delta 10, it sounds like real life. The full frequency range is conveyed with absolute authority, providing convincing, realistic sound from any genre of music. Bass instruments are full and muscular. Vocals are distinct and precise, while horns are rich and energetic, their characteristic “sheen” perfectly preserved. Drums and percussion have great impact and impressive weight. Even today’s complex, multi-layer music is reproduced with agility and nuance at any volume, from subtle indoor setting to full-volume outdoor concert. When you need even greater low-frequency extension and output, simply add either the Delta Series 15 S or 18 S subwoofer to create a system of absolutely uncompromised capability. Denon Professional recognizes that adaptability and connection flexibility are just as important to demanding professionals as outstanding sonic performance. Therefore,
