ICEpower a/s

What ICEpower a/s does

ICEpower a/s is a Danish audio technology company, founded in 1999 as a joint venture between Bang & Olufsen and the Technical University of Denmark, that develops and markets Class D amplifier modules, proprietary chipsets, switch-mode power supplies, and turnkey audio solutions. Its core technology is built around proprietary Class D amplifier topologies — including the ICEedge chipset, the GCOM (Globally Controlled Oscillation Modulator), and the new Super Conductor analog processing architecture — delivering up to 97% amplifier efficiency and 0.0002% THD+N at 100W. The product portfolio spans off-the-shelf modules from 50W consumer variants to 2,000W professional subwoofer units, paired switch-mode power supplies (400SM, 750S, 1000S, 1500S), the ICC5 intelligent audio chipset, and ICEsound embedded audio enhancement software licensed into consumer devices.

ICEpower operates a hybrid B2B revenue model combining direct enterprise sales targeting audio product OEMs with a regional sales footprint (North America, Europe, Asia Pacific) supported by field application engineers, plus a webshop channel for samples and small-batch orders. Ancillary revenue comes from end-to-end "turnkey audio solutions" — outsourced product creation from development through certification, manufacturing, and ongoing maintenance. Customer concentration spans smart home audio, commercial installation, pro audio, consumer audio, and instrument amplification segments, with named relationships including historical automotive placements (Audi, Mercedes, Aston Martin, BMW), consumer brands (ASUS, Samsung via ICEsound), and professional audio customers.

The company is privately held, headquartered in Søborg, Denmark, with engineering operations in Helsingborg, Sweden, manufacturing consignment in Malaysia and Thailand, and sales offices in the United States (New Jersey) and Japan (Takasaki). Ownership sits with management and Danish private equity (Dansk Ejerkapital / Industry Development), with a 2023 growth investment from Crestline. Following independence from Bang & Olufsen via a 2016 management buyout and the integration of Audio Bricks and Bolecano the same year, the business has pursued platform expansion through successive module and power supply launches, most recently the SC400A2 flagship.

Core offering

ICEpower develops and markets Class D amplifier modules, switch-mode power supply modules, and intelligent audio chipsets that audio product manufacturers integrate into their branded hi-fi, pro audio, smart home, commercial, and automotive audio systems. The company complements its off-the-shelf AS Series and ASX Series product platforms with a turnkey audio product creation service that takes customer projects from concept and development through certification, manufacturing ramp-up, and product maintenance.

Product overview

ICEpower a/s is a Danish audio technology company specializing in Class D amplifier modules and power supplies. The product portfolio is organized into two main amplifier series: the AS Series (intelligent audio amplifier power solutions for consumer and professional applications) and the ASX Series (modular building blocks for 1-8 channel configurations). Products range from compact 100W modules to powerful 2000W amplifiers. The AS Series includes modules with integrated power supplies (AS1/AS2 variants) as well as amplifier-only modules (A1/A2 variants) that can pair with separate power supplies. Power supply modules include the 400SM, 750S, 1000S, and 1500S. The flagship SC400A2 features the new Super Conductor topology. Beyond off-the-shelf modules, ICEpower offers turnkey audio solutions providing full custom product development from concept through manufacturing.
