Intended use

Use Mastering and mixing engineers, and critical-listening buyers, who want a complete integrated playback chain: the LS1a builds DSP crossover, calibration, D/A conversion, and NCore Class D amplification into the speaker, accepts three AES/EBU digital sources plus a stereo analog input directly, and its wide-baffle form factor is unidirectional down to 250 Hz, which Grimm states allows positioning close to a wall without wall-reflection interference. The filtered subwoofer output and DSP make later expansion to a phase-coherent three-way system with LS1s or SB1 subwoofers straightforward.
Not for Anyone who wants a conventional passive monitor for an existing amplifier chain, needs high playback levels (published LS1-series max SPL is about 105 dB at 1 m), needs full 20 Hz extension without buying subwoofers (the two-way configuration is specified down to about 40 Hz), or needs a compact nearfield that sits on a desk or meter bridge in standard form — the LS1a is a floor-standing system 1150 mm or 1450 mm tall (a Nano legs version is offered as an option). Latency of 7.3 ms (two-way) to 40 ms (three-way) may also matter for tracking musicians on headphone-free monitoring.

Description

Product details

The Grimm Audio LS1a is a two-way active monitoring loudspeaker system with built-in DSP crossover, D/A conversion, and NCore Class D power amplifiers, sold here in a white lacquer finish. It uses a polypropylene Seas woofer and a Seas DXT tweeter mounted in a wide, shallow lacquered cabinet between two cylindrical legs that form an integrated floor stand, with height options of 1150 mm or 1450 mm. It accepts one stereo analog line input and three AES/EBU digital inputs (44.1-192 kHz), offers a filtered analog subwoofer output, and can add USB input (PCM up to 384 kHz, DSD64/128) via the optional LS1i interface. Compared with the standard LS1, the LS1a uses a non-magnesium woofer, a lighter foot plate, and a lacquered cabinet, and omits the individual acoustic calibration of each cabinet while keeping DSP-controlled response correction from computer-aided calibration during production. It can be extended into a three-way system with optional LS1s or SB1 subwoofers.
