The CM890I boasts a robust 125W RMS power handling capability, ensuring that it can produce clear, dynamic sound even at high volume levels. Its two-way design features a dedicated 8" treated fiber driver paired with a high-power compression transducer, which together generate a broad frequency range with crisp highs and rich lows.

Engineered for versatility, the CM890I is ideal for distributed or 8-ohm applications, making it a suitable choice for a variety of professional settings. Whether it's for casinos, convention centers, warehouses, nightclubs, gyms, aerobic rooms, airports, superstores, arenas, theme parks, transportation hubs, shipping centers, or stadiums, this speaker is designed to handle the demands of high-SPL or long-throw applications with ease.
