Sound system
RK-QF12
The speaker features a robust, low-resonance trapezoidal enclosure that is hard and heavy, offering excellent low-frequency damping characteristics, low sound coloration, and significantly enhancing the purity of the sound.
It uses a ferrite low-frequency driver that maintains the original delicacy of the sound while also providing more powerful low-frequency output.
The high conversion efficiency makes it easier to pair with power amplifiers, easily resolving driving issues.
It has a rigorously designed built-in crossover circuit that offers superior signal frequency division performance.
Equipped with a high-frequency dynamic protection circuit, it ensures effective protection for the speaker under continuous high-output conditions.
