Sumico CL46 utilizes line array technology with six 4.5-inch woofers and one 1-inch tweeter, delivering wide sound dispersion, clear output, and minimal distortion. A pair of Sumico CL46 speakers is suitable for rooms ranging from 80m² to 150m².
The six 4.5-inch (115mm) woofers feature lightweight rigid composite fiber cones for fast transient response and precise control. Arranged vertically in a sequential line array configuration, they create a directional coupling effect that produces consistent sound pressure and delivers a thick, clean, and articulate midrange. This 4.5-inch woofer system is combined with a 1-inch (25.4mm) dome tweeter utilizing a newly engineered aluminum diaphragm to enhance high-frequency reproduction with extended range, rich detail, smooth response without harshness, and improved sound directivity within a frequency response of 100Hz – 20kHz, handling power up to 250W (RMS).
The specially engineered column line array enclosure of the Sumico CL46 not only projects sound over long distances with wide coverage but also enhances focus and directivity control. It minimizes sound reflections and low-frequency boominess in acoustically reflective environments or elongated spaces such as auditoriums, lecture halls, churches, stages, or wedding banquet restaurants, ensuring clear audio even at extended distances. With premium speaker components and optimized acoustic design, the Sumico CL46 delivers a smooth, linear frequency response, high power handling capability, and stable operation.
Acoustically Optimized Horn-Loaded Bass Reflex Port
The Sumico CL46 features a rear horn-loaded bass reflex port that rapidly releases internal air pressure, increasing sound output level and rear dispersion angle while minimizing feedback noise and low-frequency distortion. This ensures more accurate and powerful sound reproduction even at high output levels.
Durable and Flexible Design
The Sumico CL46 is designed as a high-efficiency slim column speaker with dimensions of 940mm (Height) x 180mm (Width) x 220mm (Depth). It features recessed side handles and rear mounting points, allowing users to install wall brackets, mount vertically on top of a subwoofer, or stack in low-profile configurations with flexible adjustment of the coverage angle. The enclosure is constructed from premium MDF with a textured, moisture-resistant, scratch-resistant finish, and the protective grille is made of rust-resistant powder-coated alloy for enhanced long-term durability.
Recommended Matching Amplifier
The Sumico SU450 digital karaoke amplifier integrates a digital signal processor and high-end wireless microphones, delivering a rated output of 450W per channel (8 Ohms), currently one of the most powerful in the market, capable of driving high-power speaker systems with ease. The amplifier features a high-quality 24-bit/192kHz DAC for decoding audio signals from TV and karaoke players via HDMI and Optical inputs, as well as convenient USB connectivity and modern Bluetooth streaming.
