FBT Install DUNE 660 TBR

A Speaker Designed for Outdoor "Multi-Zone" Sound Reinforcement

This type of 2-way outdoor speaker meets a simple need: to achieve consistent and intelligible sound diffusion in open spaces, where sound disperses faster than indoors. The 360-degree dispersion supports this goal by promoting more uniform coverage around the speaker, convenient for creating a musical atmosphere without having to multiply adjustments or seek a precise "listening axis."

The dual operation in 70/100 V or 8 ohms also places it in a highly versatile approach: it can be integrated into a line sound system (often used for ambient diffusion over long cable runs) or into a more traditional low-impedance configuration.

Who and What For: Ambiance, Announcements, and Outdoor Music

This speaker is suited for any situation where stable and simple outdoor sound reinforcement is desired: terraces, patios, gardens, walkways, waiting areas, circulation spaces. Its frequency response from 70 Hz to 20 kHz allows it to reproduce the essential spectrum for background music and voice, with clear rendering thanks to the 1" tweeter.

The specified sensitivity of 79 dB (1 m/1 W) and max SPL of 103 dB provide a concrete reference: the goal is pleasant and controlled diffusion, adapted to environments where a coherent sound presence is sought rather than concert-level sound pressure. The brown color contributes to a more discreet visual integration, particularly relevant in landscaped settings.

Key Features: 360-Degree Dispersion and 70/100 V or 8 Ohms Selection

360-Degree Dispersion: More Even Coverage

360-degree dispersion is a real asset outdoors: it helps distribute sound around the speaker, limiting the sensation of excessive volume nearby while maintaining intelligibility at a distance. This approach is ideal for ambient sound reinforcement, especially when listeners are moving (terrace, garden, circulation).

70/100 V or 8 Ohms: Adapt to Existing Installation

The 70/100 V mode is particularly appreciated in large or multi-zone installations, as it facilitates signal distribution over longer distances. The 8 ohms mode allows connection to more traditional amplification. This flexibility simplifies the choice, whether starting from an existing installation or building an outdoor diffusion system.

2-Way Architecture: Defined Bass, Precise Treble

The combination of a 6.5" woofer and a 1" tweeter aims for clear balance: a solid foundation for instruments and vocals, and sufficient definition in the high spectrum to preserve articulation and presence, even in an open environment.
