It is composed of 8 × 4.5" Mid-Woofers + 16 × 1" Tweeters

This column speaker offers exceptional directivity with three independently adjustable beams, allowing optimal listening experiences for audiences in multiple targeted zones. The custom-designed speaker array is powered by an 8-channel amplifier with a high-precision switching-mode power supply, ensuring reliable performance over years of use.

Unlike traditional column speakers that rely on fixed shapes (e.g., convex, concave, or angled surfaces) to influence directivity—without the ability to adjust it—this system employs a web-based phase-control interface with advanced beam-steering algorithms to achieve precise and adjustable directivity. Its high audio quality, performance, ease of use, and convenient installation make it ideal for various sound reinforcement applications, reducing acoustic energy loss and improving speech intelligibility.

Product Features

Equipped with multiple full-range dual magnetic neodymium drivers for ultra-wide frequency reproduction.

Built-in patented high-performance DSP algorithm to suppress side lobes in sound radiation.

Innovative beam-steering design enables projection of the acoustic center to up to three separate audience zones.

Vertically steerable coverage focuses sound downward to target areas while significantly reducing upward emission and ceiling reflections.

The only digital speaker with an anti-reverberation system, enhancing speech clarity in echoic environments.

User interface supports real-time display and editing of the 3D beam pattern model.

Built-in multi-band FIR + IIR equalizer.

Integrated high-sensitivity signal detection for intelligent noise gating and power control.

The enclosure of the column speaker is made of a whole extruded aluminum profile, which is small in size and light in weight, making it easy to transport and install while meeting architectural and aesthetic requirements.

Functional Interfaces

RS232 Port: Connects to a computer serial port for sending control commands (customization required).

Line Output Port: Balanced output of the input audio signal; unaffected by volume adjustments in the control interface.

Line Input Port: Balanced input for incoming audio signals.

System Upgrade Port: For firmware updates (factory use only; unauthorized access not permitted).

100V Signal Input Port: When using constant voltage input, the speaker still requires external power. Power draw from the 100V input is less than 0.1W.

Dante Input (Optional): RJ45 10/100Mbps adaptive Ethernet port.

Power Input: AC 220V, 50Hz
