Compact subwoofer system, strict maze design. The use of high-power ultra-low frequency bass, high Q resonator is designed to front and back signal simple load, control the amplitude of the unit at the resonant frequency, effectively inhibit the high-order harmonic output, deep bass, high sound pressure. Low frequencies are purified to reduce system distortion under large dynamics, which is the ideal companion for your sound reinforcement equipment, giving you rock-solid bass sound quality. In addition, the Seer Ultra Low series speaker also has a handle redesigned to conform to human engineering, making transportation extremely convenient, and a strong metal mesh can effectively protect the speaker unit. High quality components and strong construction make the speaker more robust and durable.

SLA-210 is able to handle not only mega outdoor performance where needs high and continuous SPL output but also small-medium indoor places where needs extra convenience in trucking and operation.
