Performance: Frequency response in-room within 3dB from 45Hz to over 20kHz. Linear-phase mid/top crossover. Output >105dB spl @ 1m on music material. Noise less than 15dB spl. Overall electronic distortion typically <0.02% at any frequency or level.

Inputs: DSP3100: Two S/PDIF digital inputs, 32kHz-96kHz sampling rates at up to 24 bit with MHR support. M3100: Line level unbalanced (phono) and balanced (XLR-3F) inputs, switch-selectable.

Construction: Vertical unit: 2-way ported design with 160mm bass driver; Horizontal centre: 2½-way closed box design with twin 5¼ in (120mm) bass drivers, with doped carbon fibre cones and cast alloy baskets. 1in (25mm) Meridian piston treble drive unit with doped fabric dome.

Electronics: Constructed using advanced surface-mount techniques and partitioned 4-layer printed-circuit boards. DSP3100 includes two precision 24/192 oversampling converters for bass/mid and tweeter signals; Motorola 56367 150MIPS digital signal processor; Digital crossover at 2.3kHz; Response correction for the whole system; Bass protection; User tone controls; Analogue/digital volume and phase control. M3100 features precision line-level active crossover.

Amplifiers: Two 75W power amplifiers, one for each band.

Display: Eight-character display with system lights, can be blanked.
