Styled in caramel bamboo veneer, the LS1v2 from Grimm Audio is an active all-in-one stereo speaker system designed to combine the best aspects of a high-fidelity system with the accuracy of professional studio monitors for demanding musicians, engineers, producers, and audiophiles. Part of the LS1 family, the LS1v2 is the middle-tier option, offering outstanding performance. The speaker features an 8" magnesium Seas woofer, 1" Seas DXT tweeter, heavy footplate, and carefully optimized NCore amplifiers, fine-tuned to ensure the best possible performance. The LS1i USB interface is also included, providing a direct connection to Mac or Windows computers.
Note:
The LS1be is available with legs in brown or black and at standard couch height (45") or a higher studio chair height (56"). Please call us when ordering to specify your preferences.
Analytically Precise and Musically Pleasing
Why choose between having accurate, professional-quality monitoring or having a high-fidelity system for audiophile listening when the LS1 series has been specifically designed to deliver both? The speaker incorporates top-quality DSP, converters, and amplifiers to completely control all the critical aspects of audio reproduction and ensure pure, ultra-accurate sound.
Accurate High-Fidelity Monitor Speakers
Grimm's mid-tier product, the LS1v2 is a highly accurate set of studio loudspeakers for critical studio monitoring applications and audiophile listening. Each speaker features an 8" Seas magnesium woofer and a 1" Seas DXT tweeter. In addition, the LS1v2 frequency response is linearized through smart use of DSP via a Computer Aided Calibration process during production. The speaker features a DSP-controlled frequency curve and is unidirectional down to 250 Hz with a well-behaved off-axis response, while the form factor makes positioning close to a wall possible without wall-reflection interference.
The Acoustics
The flat, wide cabinet design lowers the baffle step frequency, allowing sound below the 250 Hz range to be radiated in all directions equally, while higher frequencies, where phase problems are more perceptible, are more forward focused. The rounded legs also help to reduce the deterioration of the stereo image, while the shallow cabinet moves the resonance along the depth axis inside the box, significantly above the crossover frequency of the 8" low-frequency driver, helping to avoid boxiness. Even dispersion is also helped by the lack of cone breakup effects in the magnesium woofer below the crossover frequency. The woofer's long excursion permits generous sound pressure capability down to 40 Hz for the two way configuration. The 1" Seas tweeter's exceptionally low distortion in the midrange allows a fairly low crossover frequency that benefits vertical dispersion. Its small constant-directivity horn ensures an even spread of high-frequency sound.
The Electronics
Digital input signals are re-clocked by a state-of-the-art ASRC circuit, which is based on the same oscillator as the legendary Grimm CC1 clock. Analog inputs are first converted to digital with a high-performance A/D converter. The signal then enters the DSP, which has a datapath of 48-bit wide with a 76-bit accumulator. Each driver then has its own high-quality D/A converter. The output of the D/A converters is directly fed into 120W Hypex Ncore power amplifiers. The optional LS1s subs have an additional 400W amp each. Hypex Ncore power amplifiers have extremely low harmonic distortion and are the perfect choice for the LS1a due to their linearity and excellent transient response. Throughout the whole circuit, careful attention has been paid to component selection like capacitors and resistors. Critical parts, such as power supply regulators, are of Grimm's own discrete design.
Analog & Digital Connectivity
The LS1v2 has versatile connections for analog and three digital AES/EBU sources. The system also includes the LS1i USB audio interface, allowing any computer to become your audio source. The LS1r remote controller or an MU1 music player (both available separately) allow for convenient control of volume and source selection.
Subwoofer Available Separately
An LS1v2 covers the full frequency range as an elegant two way system. By adding an optional LS1s or SB1 subwoofer set, the LS1v2 becomes a very low distortion three way loudspeaker that can handle all music styles in any size room. The advanced Digital Motional Feedback (SB1) subwoofer has an impressive 30 dB lower distortion, which means the bass area is now just as transparent as the mid and treble.
