Styled in a caramel bamboo veneer, the LS1be 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 LS1be is the top-tier option, taking the system's outstanding performance to new heights with a stunning finish and upgraded components. The speaker features an 8" magnesium Seas woofer, 1" Seas beryllium tweeter, and a heavy footplate. In addition, the LS1be has been carefully fine tuned during assembly to optimize the speaker for the best possible performance. The LS1i USB interface is also included, providing a direct connection to Mac or Windows computers and allowing the speaker to support digital PCM audio at resolutions up to 24-bit / 384 kHz (DXD) as well as the DSD64 & DSD128 formats.

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.

Grimm's flagship product, the LS1be takes the LS1 performance to the next level. Aiming to improve transparency even further by focusing on “authority, control, and flow”, the engineers at Grimm worked on lowering distortion and extending the linear audio band. The result is a speaker that delivers stunningly accurate monitoring for demanding professionals and a musical listening experience for serious sound connoisseurs. The speaker features an 8" Seas magnesium woofer and an upgraded 1" Beryllium tweeter, co-developed with Seas, that extends the frequency range and provides 9 dB less distortion than the original tweeter. Furthermore, the LS1be features lowered jitter, improved power supplies, and exclusive component selections, including silver power supply wiring for the finishing touch. In addition, the LS1be frequency response is linearized through smart use of DSP via a Computer Aided Calibration process during production.

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.

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.

The LS1be 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.

An LS1be covers the full-frequency range as an elegant two-way system. By adding an optional SB1 subwoofer set, the LS1be becomes a very-low distortion three-way loudspeaker that can handle all music styles in any size room. The optional 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.

Related Questions and Answers

Q: 1. Can the be played with 240V power supply?

A: Yes, these speakers are dual voltage. 115/240VAC, 50/60Hz selectable.

Q: 2. working with limited space, 8" shelf but has 12" depth & 4ft width. can these speakers be placed on their side and still work good? also does it come with anything to decouple the speakers from a tv stand/shelf?

A: It is not recommended but sure you can do that and they will still work good. The A5+ does not come with any attachments for a stand, they are made to sit on any flat surface.

Q: 3. Can these be used as computer speakers? I like a lot of bass, and currently using klipsch pro media 2.1 speakers.

A: I believe A5+ can be computer speakers because they are active speakers comes with amplifier embedded. However, they are too big if you put them next to my 27 monitor. Imagine it will looked so out of proportion with smaller monitor. I suggest you use A2+ and add a subwoofer to give better bass than A5+ can provide. A2+ will be less costly. Money saved can pay a portion of a sub. I currently use A5+ on speaker stands with a 4K TV, which put out terrible sound quality. I am an audiophile and I cannot recommend A5+ or A2+ as hifi speakers for music listening. They are just OK speakers and cost effective.

Q: 4. can it operate while charging?

A: Yes, the Wi Digital AudioLink Pro Pocket Portable Wireless Instrument and Audio Monitoring System can operate while the components are charging.

Q: 5. Can I play music off my iPhone?

A: Yes - you can plug them in directly through the headphone jack on your phone, or purchase a Bluetooth receiver.

Q: 6. Can multiple transmitters be synced to a single receiver with the AudioStream Pro EL? I want to mic multiple speakers and have all voices blended into a single channel.

A: You can't do quite what you want yet. But Wi Digital AudioStream systems are very unique and versatile.

Q: 7. Does this speaker have an energy saver that delays the startup of sound? I hope not...

A: Don't know of any delay. No energy saver . We usually select music after units are turned on. Awesome speakers. Placement important for maximum enjoyment.

Q: 8. Can I ask if these come with the charging docks or do they need to be purchased separately?

A: This does not include charging docks.

Q: 9. These speakers have no sub-out connection. How can these be connected to a sub-woofer in such a case?

A: The Kali Audio Project Lone Pine LP-UNF 4.5" Ultranearfield Studio Monitoring System (Black, Pair), B&H # KALPUNF, has no audio output for a subwoofer; a subwoofer cannot be connected to this system.

Q: 10. Do both units support mic and headphone? Basically, is it 2-way?

A: The Wi Digital AudioStream Pro EL is 2-way as a system, but not standalone. 2-way communication is achieved when the transmitter is connected to a computer or iPad, and then you connect a headset mic with a TRRS connection into the receiver. This allows users to wirelessly connect to a device, and have the ability to send and receive audio.
