The 3100 series from Meridian represent new benchmarks in the development of compact, high- performance active loudspeakers.

The DSP3100 DSP loudspeaker and its active analogue counterpart, the M3100, are designed for use as bookshelf or stand-mounted loudspeakers. Specially-designed aluminium stands are available that may be sand-filled for maximum stability and to minimize any impact on sound quality. The vertical units also include universal wall bracket mountings for additional flexibility in location. The horizontal centre unit is magnetically-shielded.

3100s are tonally similar to other Meridian loudspeakers and as a result they are ideal for use, for example, as surrounds in a Meridian system. They are equally suited for use in a smaller stand-alone system in a study or bedroom, and can be used as second zone speakers in a Meridian multi-room environment. The DSP version features S/PDIF digital inputs at up to 96kHz while the analogue version includes switched balanced and unbalanced inputs, so either can also be used as high-end computer loudspeakers.

Extremely accurate characteristics make either 3100 version eminently suitable for studio monitoring applications, particularly as a near-field or surround monitor in recording and mastering facilities: the DSP3100 accepts standard digital audio at sample rates up to 24- bit, 96kHz.

Construction

The DSP3100’s distinctive cabinet is made from braced wood with piano-

lacquered ends and aluminium side- panels bonded for rigidity.

The 3100 offers extremely low colora- tion, and this is partially a result of this cabinet construction. Wood tends to vibrate at lower frequencies, where aluminium is very stable; conversely, aluminium tends to resonate at higher frequencies while wood does not. Combining the two by bonding them together tends to cancel out vibration across the range. The cabinet is further damped with bitumen, leading to an enclosure that is exceedingly dead.

Cosmetic finishes available are black or silver, matching Meridian’s G Series components (bead-blasted, brightened and anodised).

The vertical units feature a 2-way rear- ported enclosure, while the horizontal centre is a 2½-way closed box design.

Featuring high-efficiency long-throw 6in (160mm) (vertical model) or dual 5

¼in (120mm) (horizontal model) bass drivers with doped carbon fibre cones and cast alloy baskets, the 3100 also includes a very high quality 1in (25mm) Meridian piston treble drive unit with doped fabric dome.

Electronics

The drivers are powered directly by independent high power, low feedback amplifiers fed from an audiophile- grade power supply with a substantial toroidal transformer. DSP power in the DSP3100 is a provided by a Motorola 56367 running at 150MHz; D/A conversion is handled by dual 24-bit, multi-bit delta-sigma converters. The DSP3100 may be controlled via RS232, and both analogue and digital versions may be operated by an infrared remote control unit such as the MSR+.
