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.

Solid Fundamentals
The Delta 18 Sub powered subwoofer is designed to add the deep, solid bass foundation needed for convincing, lifelike music and multimedia presentations.  It features an integral low-distortion Class D amplifier capable of 2400 watts peak output (1200 watts continuous), a rugged 18-inch LF transducer, DSP-controlled custom crossovers, EQ contour switch and a computer-designed vented enclosure for optimum low-frequency response at high SPLs with minimal distortion. The Delta 18 Sub has extremely flexible connection/control facilities for adapting to any usage condition. Plus, it utilizes dynamic thermal protection, to ensure reliable, crystal-clear bass reproduction— even at extreme volume levels.

However, it’s not the printed specifications or the number of inputs and outputs that qualifies the Delta 18 Sub as such an elite performer. It’s the performance. The quality and depth of the bass is effortless, powerful and natural. There is no sense of strain or distortion; the sound is utterly authoritative. With lesser subwoofers, the listener can immediately hear the “reproduced” nature of the bass: the thin, lightweight character to the sound, the lack of ‘weight’ that should be more felt than heard. This is what betrays the sound of an inaccurate subwoofer.

When you hear the Delta 18 Sub as part of a full Delta sound system, it sounds stunning. 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 supported with while 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 settings to full-volume outdoor concerts.

The Right Connections
Denon Professional recognizes that adaptability and connection flexibility are just as important to a successful event as outstanding sonic performance. Therefore, the Delta series features a built-in mixer with multiple inputs and outputs. The cabinets are scratch-resistant, fronted with a powder-coated metal grille—perfect for anything from vocal reinforcement in a lecture hall to music-rich multimedia presentations in convention. Even their rubber feet are reinforced with steel. You can hang the Delta series via their integrated M10 rigging points or use the “tops” as floor wedge monitors. The Delta 18 Sub features a built-in industry-standard 35mm pole sockets.  This level of connection and mounting options means that virtually every situation benefits from using Delta Series loudspeakers.

Remote Control
Even if you can’t physically reach the speakers, you can still adjust them with your iPad or iPhone uing the Drive iOS app. With our wireless technology, you can precisely tailor the performance parameters of your Delta Series loudspeakers remotely. Level-match, adjust EQ, delay-compensation and more—from virtually anywhere. It’s streamlined, sound-shaping control at your fingertips, so you can easily adapt the Delta Series to new venues or performances, even if you’re away from the mix position.
