Grimm Audio LS1v2 Active Loudspeaker

The Grimm Audio LS1v2 is a precision floor-standing active loudspeaker system that redefines what true accuracy means in professional monitoring. By integrating high-end digital signal processing, conversion, and amplification directly into the speaker’s structure, the LS1v2 functions as a complete audio system—requiring only an analog or digital line source to deliver uncompromising performance. Designed for mastering and mixing engineers who demand neutrality and transparency, the LS1v2 reproduces music with natural musicality while exposing every detail and imperfection with surgical clarity.

Its innovative design features a wide, shallow sealed cabinet suspended between two cylindrical legs that act as both a stand and diffraction control system. An 8” magnesium woofer and 1” dome tweeter are seamlessly crossed over at 1550 Hz using an IIR-based DSP crossover with LR4 slopes and advanced phase correction, ensuring a maximally linear response without the pre-echo artifacts common in FIR systems. The result is effortless coherence, accuracy, and imaging that reveal the finest rhythmic and tonal structures.

The LS1v2 employs Seas audiophile-grade drivers, powered by dual 180W NCore Class-D amplifiers housed within the leg assembly, alongside a 48/76-bit DSP engine, digital I/O, and a master clock circuit derived from Grimm’s CC1. Computer Aided Calibration ensures a linearized frequency response with controlled bass down to 35 Hz. For those requiring extended low-end performance, a DSP-controlled subwoofer output allows seamless integration with Grimm’s SB1 or LS1s subwoofers, turning the LS1v2 into a full three-way system. With optional control from the MU1 music player or LS1r remote, the LS1v2 combines precision engineering with intuitive usability for the most demanding studios.
