cerasonar concrete one

Outdoor Design Loudspeaker – 2 × 125 W RMS / Dual 8 Ohm

The cerasonar concrete one combines exceptional outdoor audio performance with timeless architectural design. Crafted from solid concrete, it has been developed for larger gardens, terraces, hospitality environments and landscape projects where powerful sound should integrate naturally into the surrounding architecture.

Unlike conventional outdoor loudspeakers, the concrete one has been engineered around a unique ground-reflection acoustic concept. Its drivers radiate downwards towards the ground, while the specially developed crossover has been precisely tuned to utilise the acoustic reflection of hard surfaces such as concrete, natural stone or tiled flooring. This creates a wide, natural and immersive listening experience while allowing the loudspeaker to blend discreetly into the landscape.

For optimum acoustic performance, the concrete one should be installed on a solid surface such as concrete, stone or paving. Soft surfaces including grass, gravel or bark mulch reduce the intended reflection of the mid and high frequencies and are therefore not recommended.

A unique feature of the concrete one is its single stereo capability. Both left and right audio channels can be reproduced from a single loudspeaker, making it the ideal solution for outdoor areas where only one speaker can be installed while still providing a spacious stereo listening experience.

Designed as both a loudspeaker and an architectural design object, the solid concrete enclosure blends effortlessly into modern outdoor environments. Available in grey, anthracite and white, with either a smooth or rough surface finish, every loudspeaker combines long-term durability with timeless aesthetics.

For applications requiring even greater low-frequency performance, the concrete one can be combined with the cerasonar concrete sub, creating a powerful full-range outdoor audio system with exceptional bass authority and dynamic headroom.

For the best possible listening experience, cerasonar recommends pairing the concrete one with the cs-500dsp4 or cs-2000dsp4 DSP amplifier together with the dedicated factory DSP preset. Developed specifically for the concrete one, the factory DSP preset refines tonal balance, optimises overall sound quality and ensures reliable loudspeaker protection.

Alternatively, compatible third-party DSP amplifiers, including LEA Professional and Powersoft, may be used with the appropriate cerasonar factory DSP preset.
