Compact Invisible Loudspeaker – 25 W / 8 Ohm

The cerasonar 1520 fit is the most compact loudspeaker within the cerasonar portfolio, offering an ideal balance of performance, installation efficiency and value. Designed for residential and commercial projects alike, it delivers natural sound reproduction while remaining completely invisible behind plaster.

Its compact dimensions make the 1520 fit particularly suitable for bathrooms, kitchens, bedrooms, hotel rooms, corridors, cabins and other spaces where installation depth is limited. Despite its size, the loudspeaker provides excellent speech intelligibility and balanced musical reproduction for background music and everyday listening applications.

Engineered for long-term reliability, the 1520 fit is suitable for humid environments including bathrooms, spa and wellness areas, yachts and cruise ships. Carefully selected moisture-resistant materials ensure dependable operation even under demanding environmental conditions.

The loudspeaker is available as a standard 8 Ohm version as well as a model with an integrated 100V line transformer, providing flexibility for both low-impedance systems and distributed audio installations.

For optimum performance, the cerasonar 1520 fit should be operated with a suitable DSP amplifier together with the dedicated cerasonar factory DSP preset. The preset has been specifically developed for the loudspeaker, optimising tonal balance while providing reliable loudspeaker protection without requiring an additional protection unit.

Depending on the project requirements, the loudspeaker can be combined with the cerasonar cs-150smart2 streaming DSP amplifier, the cerasonar cs-500dsp4 DSP amplifier or compatible third-party DSP amplifiers from LEA Professional and Powersoft.

When operating without a cerasonar DSP preset, the appropriate cerasonar protection unit must be used to ensure safe operation and long-term loudspeaker reliability. For installations using conventional AV receivers or high-power streaming amplifiers, cerasonar recommends the cerasonar protection unit pro 50/100w, which can also be configured to 25 W for the cerasonar 1520 fit.

FIT SERIES

COMPACT INVISIBLE SOUND. BUILT FOR REAL PROJECTS.

The cerasonar fit series is a compact family of invisible loudspeakers for residential, hospitality and commercial interiors. Three distinct models provide a clear choice for discreet everyday audio, single-stereo applications and distributed 100v systems.

THREE MODELS. ONE COMPACT APPROACH TO INVISIBLE SOUND.

WHY THE FIT SERIES

COMPACT BY DESIGN. FLEXIBLE BY NATURE.

The cerasonar fit series was developed for architectural audio projects where installation space, visual discretion and straightforward system planning are equally important. Its compact construction supports residential, hospitality and commercial applications without reducing the loudspeaker to a single use case.

01

COMPACT INSTALLATION FORMAT

The shallow, space-conscious construction supports discreet integration into suitable walls and ceilings, including projects where installation depth is limited.

02

SUITABLE FOR RETROFIT PROJECTS

The compact dimensions can simplify integration into existing interiors where the available cavity, surface construction and installation conditions have been professionally assessed.

03

FLEXIBLE AMPLIFIER CONCEPT

The low-impedance models can be used with cerasonar DSP amplification or suitable conventional amplifiers together with the matching protection unit.

04

DEDICATED COMMERCIAL 100V MODEL

The 1520 fit - 100v includes an integrated 100v transformer, creating a compact solution for distributed commercial audio without requiring an external transformer.

ONE COMPACT LOUDSPEAKER FAMILY FOR RESIDENTIAL, HOSPITALITY AND COMMERCIAL AUDIO.

CONVENTIONAL AMPLIFIERS

THIRD-PARTY AMPLIFICATION REQUIRES THE MATCHING PROTECTION UNIT.

The low-impedance fit models can also be used with suitable conventional amplifiers. The corresponding protection unit must be installed between the amplifier and loudspeaker. cerasonar DSP amplification remains the recommended solution for matched tonal optimisation, Dynamic Bass Enhancement and preset-based protection.

MODEL CONVENTIONAL AMPLIFIER PROTECTION SOLUTION APPLICATION NOTE
1520 FIT ✓ protection unit 25w For suitable conventional low-impedance amplifiers.

INSTALLER NOTE

Protection units are intended exclusively for installations using conventional low-impedance amplifiers. Factory-designed DSP presets, Dynamic Bass Enhancement and preset-based loudspeaker protection are available with compatible cerasonar DSP amplifiers. The 1520 fit - 100v is designed for dedicated 100v line systems and must not be connected to a conventional low-impedance amplifier.
