Grimm Audio LS1v2 Loudspeaker

For decades, audiophiles have been told they must choose between accuracy and musicality. The Grimm Audio LS1v2 is the revolutionary loudspeaker system that proves you can have both. This is not just a loudspeaker; it is a complete, fully integrated audio system that houses its own state-of-the-art DSP, D/A converters, and NCore power amplifiers within its elegant legs. By controlling the entire playback chain from a single design vision, the LS1v2 achieves a level of time-domain accuracy and frequency linearity that is simply impossible with separate components. The result is a sound of breathtaking transparency that reproduces a beautiful recording with all its emotion intact, while also being an unflinchingly honest tool for the most demanding audio professionals.

Key Features

• Fully Integrated Active System: A complete playback system with internal DSP, D/A converters, and NCore power amplifiers for the purest possible signal path.
• DSP Controlled Frequency Curve: A powerful DSP linearizes the frequency response and allows for a controlled bass response down to 35 Hz from a compact cabinet.
• Advanced DSP Crossover: A 4th order IIR crossover with subsequent phase correction results in a maximally linear phase response without the pre-ringing artifacts of FIR designs.
• Unidirectional Sound Field: The unique wide-baffle cabinet is designed to be unidirectional down to 250 Hz, dramatically reducing unwanted room reflections for a clearer, more focused stereo image.
• Audiophile Quality Seas Drivers: Features a high-quality 8” magnesium woofer and a 1” dome tweeter for superb resolution and natural tonality.
• Super Low Distortion Amplification: Employs two 180W NCore class D power amps per speaker for absolute control and vanishingly low distortion.
• Digital and Analog Inputs: Accepts both digital and analog sources for complete system flexibility.
• Seamless Subwoofer Integration: Features a filtered analog subwoofer output designed for perfect integration with the SB1 Digital Motion Feedback subwoofer.
• Legendary Grimm Clocking: The internal digital processing utilizes the same ultra-low jitter clock circuit found in the legendary Grimm CC1 master clock.
• Remote Controllable: Volume and source selection can be controlled via the optional LS1r remote controller or MU1 music player.

The "One System" Philosophy

The LS1v2 is built on a radical principle: ultimate transparency can only be achieved when the entire playback chain is a single, optimized system. By integrating the DSP, D/A converters, amplifiers, and drivers into one chassis, Grimm Audio's designers have complete control over every interaction. This allows them to correct for nonlinearities in a way that is simply impossible with separate components. The result is an incredibly linear amplitude and phase response, vanishingly low distortion, and a sound that is so coherent and seamless it sounds as if it's emanating from a single point in space.

Acoustic Precision by Design

The unique form of the LS1v2 is a direct result of its acoustic function. The small, 14-litre sealed cabinet is much wider than it is deep, creating an effective baffle that controls the sound dispersion down to 250 Hz. This unidirectional characteristic means you hear more of the direct sound from the speaker and less of the reflected sound from your room's walls, resulting in a dramatically clearer and more stable stereo image. The cabinet is suspended between two elegant legs, which not only provide support but also combat diffraction for a smoother, more natural sound.

The Brain: Advanced DSP Correction

The LS1v2's digital signal processor is far more than a simple crossover. It is the brain of the entire system, meticulously correcting the frequency curve to be perfectly linear. Grimm Audio employs a sophisticated IIR crossover that imposes exact acoustic slopes, and then corrects the phase using an idealised inverted all-pass filter. This unique approach results in a maximally linear phase response without the pre-echo artifacts that can give FIR-based DSP speakers a "digital" sound signature. It’s this level of temporal accuracy that makes the sound so natural, realistic, and completely non-fatiguing.

The Heart of a Professional System

Despite its elegant looks, the LS1v2 is a formidable professional tool, intended as a main monitor in the most demanding mixing and mastering studios. Its unflinching accuracy reveals every imperfection in a recording, while its inherent musicality makes long working sessions a pleasure. For those requiring full-range, high-SPL performance, the DSP-controlled subwoofer output allows for perfect integration with the SB1 subwoofer, effectively turning the LS1v2 into a perfectly phase-aligned three-way system. When paired with the MU1 music player, the entire system can be controlled with seamless elegance.
