The AL7 features a unique water-filled base that can weigh up to 110kg when filled, providing balanced weight distribution and stability. The base includes drainage holes for easy setup. The stand employs a two-section telescopic design, adjustable in height from 2.8 meters to 4 meters, allowing for customizable speaker positioning. Two speakers can be suspended, with the middle section fixed at 1.7 meters and the top extendable up to 4 meters. The suspension brackets enable tilting (0° to -30°) and lateral adjustments (up to 180°) for optimal placement. Additionally, the stand includes a 1.5-meter-long lighting crossbar that supports up to 10 stage lights. Four diagonal support pillars reinforce the connection between the base and the main pole, which is coated for corrosion resistance, ensuring durability in outdoor conditions.
