Outdoor Architectural Subwoofer – 12"

Name: cerasonar concrete sub
Brand: cerasonar
SKU: 1213-1
Availability: InStock

The cerasonar concrete sub has been developed to deliver powerful, controlled low-frequency reproduction for premium outdoor audio systems. Crafted from genuine fibre-reinforced, polymer-modified concrete, it combines exceptional acoustic performance with outstanding durability, making it ideally suited for demanding residential, hospitality and landscape architecture projects.

Designed as the perfect low-frequency extension for the cerasonar concrete mini v2 and cerasonar concrete one, the concrete sub provides the foundation for true full-range outdoor audio while maintaining a harmonious architectural appearance. Its concrete enclosure blends naturally into modern gardens and outdoor living spaces, preserving the discreet design language of the entire cerasonar concrete series.

Internally, the enclosure is reinforced using moisture-resistant Tricoya® panels and assembled with stainless-steel hardware to ensure outstanding long-term durability under demanding outdoor conditions. An integrated Speakon® connector allows the loudspeaker cable to be disconnected quickly and safely, making seasonal removal or maintenance particularly straightforward.

Two performance versions are available to suit different project requirements. The Standard Performance model features a custom-developed 12-inch Kevlar sandwich woofer with dual voice coils, delivering 250 W RMS of clean, controlled and dynamic bass reproduction for premium residential outdoor systems. For larger installations and the highest acoustic demands, the Reference Performance model incorporates a heavy-duty 12-inch aluminium-cone woofer capable of handling up to 700 W RMS, providing exceptional output capability, effortless dynamics and remarkably deep bass extension.

The cerasonar factory DSP preset is available for the cerasonar cs-500dsp4 DSP amplifier, the cerasonar cs-2000dsp4 DSP amplifier as well as compatible DSP amplifiers from LEA Professional and Powersoft, allowing seamless integration into a wide variety of residential, hospitality and commercial outdoor audio systems.

Developed as part of the complete cerasonar concrete series, the concrete sub, concrete mini v2, concrete one and the dedicated cerasonar factory DSP presets have been engineered to work together as one perfectly integrated outdoor audio system, delivering exceptional sound quality while preserving the timeless aesthetics of contemporary landscape architecture.

Fresh and unique

Concrete

Our new cerasonar concrete series blends harmoniously into any landscape. Available as full-range speaker and subwoofer, this series delivers superior sound quality with 360° dispersion into any garden.

customised

Each item is an unique piece of art.

The cerasonar concrete products are available in grey (standard), anthracite and white. The top surface is available smooth (standard) or rough. Colour deviations are part of the vivid appearance of the concrete.

Excellent durability and dimensional stability

The additional reinforcement in combination with the powerful bass drivers produce an extremely dry bass. For extreme durability for outside conditions, we chose high-performance, waterproof medite tricoya extreme MDF panels, manufactured from sustainable FSC® forestry for the cabinet.

What to do when winter comes?

Our concrete series can simply stay outside in cold and harsh weather conditions. But if you do want to bring it inside, this can be easily done with the help of the speakOn connectors.
