What CELTO Acoustique does
CELTO Acoustique (rebranded to CELTO in 2025) is a Belgian professional audio company established in 1999 and headquartered in Braine-l'Alleud, Belgium. The company designs and manufactures professional sound reinforcement systems for installation, portable, touring, and transducer applications, with products deployed on five continents. CELTO sells exclusively through a global network of certified distributors (covering Europe, Asia, Oceania, Africa, Middle East, and the Americas) and does not disclose public pricing—sales are quote-based.
The product portfolio spans line array speakers (IWAC210 G2, ISORAY10+), point source coaxial loudspeakers (iFIX G2 series, CT series, PM series), subwoofers (CSW, SU, iFIX, and ACS218 lines), a full amplifier range (C, P, S, SL Class D series), DSP controllers (D48), and a premium transducer line sold both as OEM components and integrated within finished systems. CELTO manufactures 100% of its transducers in-house, which underpins proprietary technologies including the patented IsoTop Waveguide, the Active Curvature System (ACS), the world-first HFD44/C carbon dome HF compression driver with DuPont Polyimide surround, the world's first 350°C thermal class voice coil wire (XHT), and most recently low-temperature diamond-coated carbon diaphragm compression drivers (HFDN44/DC3, HFDN754/DC3). Performance specifications are aggressive: the ISORAY10+ delivers 136 dB peak SPL in an A3-sized 15.5 kg cabinet; the ACS218 reaches 139 dB peak SPL with 3000W RMS; the IWAC210 G2 scales to audiences of 30,000.
CELTO generates revenue through professional audio hardware sales to system integrators, rental companies, touring productions, and venue owners, with a horizontal segmentation across installation/sound architecture, portable/professional sound, touring, and transducers. Customer concentration is spread across hospitality/nightlife (e.g., Justin Timberlake's 12|30 Super Club in Nashville with 150+ speakers, Enigma, Kommunity, Eclipse, Supernova clubs), hospitality/restaurants and hotels (Virgin Hotels New York, BellBoy Berlin, Hu Beach Club Vietnam, Chacha Balik Istanbul), education (SKUAST Jammu University, JIIT India), houses of worship (Swarved Mahamandir, Shree Lakshmi Narayan Mandir Kuala Lumpur), festivals and events (SBS Fantastic Duo TV, LG Dream Festival, Osaka Expo 2025 Belgian Pavilion), and rental companies (RUI Sound South Korea with 200+ IWAC units, SL Productions Netherlands, Soundrite Audio South Africa).
