This three-way proximity and mid-range monitor achieves a surprising level of precision thanks to a new soft dome tweeter, midrange speaker and Dynaudio's exclusive MSP woofer . Each speaker is powered by a powerful, state-of-the-art Class D amplifier and a fully 24-bit / 96kHz circuit. And, like the rest of the LYD range, it lets you fine-tune low-frequency response, position, and balance using state-of-the-art DSP.
