Product Description

Product Ref:DN104S

Denon Professional's range of ceiling loudspeakers are designed to deliver exceptionally accurate, articulate sound while easily meeting commercial requirements for fire-resistance and suitability for multiple unit installation.

The Denon DN-104S features a metal "can" rear enclosure, which provides a fire barrier behind the speaker to meet commercial fire codes. It also serves as the woofer's enclosure to optimize its bass tuning and low frequency response. The speaker has 70/100-volt transformers to facilitate multiple unit installations without the impedance and level-matching concerns of paralleled transformerless speakers.

The DN-104S has 4-inch woofer and utilizes a high quality drive unit in a tuned reflex enclosure and precision electronic crossovers to deliver clean, detailed sound, perfect for music, public address applications and business/educational presentations, while meeting all safety and fire codes as required by commercial venues. Supplied as a pair.
