Denon Delta 15 overview

  • 1Description

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.

  • Unrivaled acoustic accuracy via advanced engineering and design
  • 2400 watts peak Class-D power (1200 Watts continuous)
  • 15" LF transducer
  • 1.75” HF driver with 1” acoustic aperture
  • Optimized 90° x 60° sound coverage field
  • Works with free Live Drive iOS app for wireless sound-shaping control
  • Wirelessly level-match, EQ, delay-compensation, and more

    Denon Delta 15 reviews

    Delta 15 - 15" 2-Way Powered Loudspeaker with Wireless Connectivity (2400 W) is rated 3.8 out of 5 by 4.
    Rated 5 out of 5 by from Powerful clear mains. This is an amazing price on quality plywood cabinets. I was going to buy another alto ts215 powered mains, but saw this (same as the alto black 15) for only $50 more and very happy with the purchase. I actually ended up getting another one to have a matching set. I don't have much experience, but I have played at two events since this purchase and gotten several compliments. One guest was an amateur musician and couldn't believe how low the price was. I don't have any apple products to use the bluetooth, but haven't needed to use any of the DSP functions. If you need mid level powered speakers on at an entry level price point, you can't beat these.

    Rated 1 out of 5 by from No wireless connectivity anymore Can’t find the app to connect to the speaker anymore. I try to contact customer service from Denon and their answer is the app was disconnected. Hello! I just bought it in March 2018. Alto and Denon will not be my choice anymore.

    Rated 4 out of 5 by from Denon Delta at half the price on sale! Exactly the same as Alto Black at half the price. They beat!
