Cerasonar ARCHITECT SUB Architectural Subwoofer

Vibration-Controlled Architectural Subwoofer The cerasonar architect sub has been developed for projects where extended low-frequency performance is required, but conventional invisible subwoofers are not suitable due to vibration-sensitive constructions, limited installation space or demanding architectural requirements.‎ Unlike traditional architectural subwoofers, the architect sub features a mechanically decoupled enclosure with integrated vibration dampers.‎ This significantly reduces the transmission of structure-borne vibrations into surrounding walls, ceilings and furniture, helping to minimise unwanted rattling and resonance while maintaining precise, controlled bass reproduction.‎ Its discreet bass outlet, connected to the enclosure via a flexible acoustic duct, allows the subwoofer cabinet to be positioned independently of the visible sound outlet.‎ This provides exceptional installation flexibility while preserving clean architectural lines and an almost completely invisible appearance.‎ The architect sub has been specifically developed as the ideal low-frequency extension for the cerasonar 4062 architect, creating a remarkably balanced invisible audio solution for ultra-shallow installations.‎ It may also be combined with other cerasonar loudspeakers wherever structure-borne vibrations must be minimised, making it particularly suitable for lightweight metal stud constructions, bespoke furniture, renovation projects and acoustically sensitive environments where conventional invisible subwoofers cannot be used.‎ The cerasonar factory DSP preset has been specifically developed for the architect sub, optimising system integration, extending low-frequency performance, activating the proprietary Dynamic Bass Enhancement and providing reliable loudspeaker protection.‎ 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.‎ For the majority of installations, the cs-500dsp4 is the recommended amplifier, while the cs-2000dsp4 offers additional flexibility for larger systems and more complex DSP configurations.‎ Technical specifications: • Power rating: 150 W RMS (300 W max) • Impedance: 4 Ohm • Frequency range: 35–150 Hz* / *² • Frequency range with cerasonar amplifier: 30–150 Hz* / *² • Maximum SPL: 108 dB • Dispersion: hemispherical • Single-stereo mode: no • Suitable for humid environments: no • Drywall: suspended ceilings with at least 210 mm space; maintain at least 5 mm between subwoofer and plasterboard • Vent: 85 × 85 mm • Dimensions: 350 × 275 × 200 mm • Weight: 8.‎5 kg • Supplied acoustic duct length: approx.‎ 450 mm * depending on the installation situation 108 dB @ 70 Hz with 300 mm duct; 105 dB @ 50 Hz with 450 mm duct Further info from manufacturer on ARCHITECT SUB Cerasonar
