Product Description:

i-4000ND is a built-in two-way linear speaker of all-NdFeB speakers, consisting of two 10-inch 65-core voice coil bass and two 44-core tweeters. High-efficiency tweeter waveguide, vertical control angle 0~8°, horizontal coverage angle ≥100°. The box is equipped with a special hanging angler for fine angle adjustment. The box is processed with 9 layers of imported birch boards, and the exterior is designed with environmentally friendly water-based paint and waterproof system.

System features: small size, large dynamics, high fidelity, long range; external aluminum alloy structure hanging system, equipped with special hanging angle.

Suitable places: outdoor large and medium-sized performances, indoor large-scale concerts

i-4000ND uses two patented certification technologies

1. Aluminum front load panel application technology

Strip diffraction port. The function is to effectively control the air compression ratio, improve the sensitivity of the mid-frequency area, and make the sound propagate farther.

2. Improve the die-cast aluminum junction box plug connection method. When the line array is hung, the weight of the speaker cable connected is 5~15 kg. Usually, the plug is connected vertically behind the speaker, which has a large cross-cutting force. After long-term use, the contacts will loosen, increase the conductor resistance, and even break the circuit without sound. Applying this patented technology, the plug forms a 60-degree angle with the speaker back panel, reducing the cross-cutting force by 75%. Moreover, the hidden design avoids collision and damage to the plug and socket during equipment installation.
