Active loudspeakers 2.0 with a power of 42W have a smooth frequency response for a great sound reference. 1-inch silk dome tweeter and 4-inch diaphragm woofers deliver clear sound. Wooden MDF plywood minimizes acoustic resonance. The speakers can easily be connected to mixers, audio interfaces, computers or other audio players. They are equipped with a front headphone output and AUX input, a multi-function knob for switching power, volume and sound effects. They have switchable modes for monitoring or listening to music. With a special dual sound effect, the user can choose monitor mode to listen to the real sound you create for music production, or switch to music mode for a music listening experience. With a 4-inch woofer and Class-D amplifier support, the frequency can be cut down to 60Hz to fully realize the remarkable low-frequency performance.
