The DSP3100 from Meridian represents a new benchmark in the development of compact, high-performance digital loudspeakers.
Cabinet design
The DSP3100’s distinctive cabinet is made from braced MDF with piano- lacquer ends and aluminium side-panels bonded for rigidity. The DSP3100 offers extremely low coloration, and this is partially a result of this cabinet construction. Wood tends to vibrate at lower frequencies, while aluminium is very stable; conversely, aluminium tends to resonate at higher frequencies while wood does not. Combining the two by bonding them together as
in the DSP3100 tends to cancel out vibration across the range. In addition, the cabinet is further damped with bitumen, leading to an enclosure that is exceedingly dead.
The DSP3100 is intended for use as a bookshelf or stand-mounted loudspeaker – specially-designed aluminium stands are available for the vertical units that can be sand-filled for maximum stability and minimal impact on sound quality. In addition, the vertical units include Omnimount/ universal wall bracket mountings for additional flexibility in location. The horizontal centre unit is designed to sit on a shelf. Feet are fitted to the units.
The speakers are tonally similar to other Meridian DSP loudspeakers and as a result they are ideal for use, for example, as surrounds for a Meridian DSP-based 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. With S/PDIF digital inputs at up to 96kHz, they can also be used as high-
end computer loudspeakers.
The extremely accurate characteristics of the DSP3100 make them eminently suitable for studio monitoring applications, particularly as near-field or surround monitors in recording and mastering facilities, where they can accept digital audio data at standard digital recording sample rates up to 24- bit, 96kHz operation.
Inside the DSP3100
Featuring high-efficiency long-throw 6in (160mm) (vertical model) or dual 5 1⁄4 in (120mm) (horizontal model) bass drivers with doped carbon fibre cones and cast alloy baskets, the DSP3100 also includes a very high quality 1in (25mm) Meridian piston treble drive unit with doped fabric dome. The drivers are powered directly by independent high power, low feedback amplifiers fed from an audiophile-grade power supply with a substantial toroidal transformer.
The DSP power in the DSP3100 is provided by a Motorola 56367 running at 150MHz, while D/A conversion is handled by dual 24-bit multi-bit delta- sigma converters. The vertical units feature a 2-way rear-ported design with a single 160mm bass driver, while the horizontal centre is a 2 1⁄2-way closed box design featuring twin 5 1⁄4 in (120mm) bass drivers.
The DSP3100 may be controlled and configured via RS232, and operated by an infrared remote control unit (not supplied).
Cosmetic finishes available are black or silver, matching Meridian’s G Series components (bead-blasted, chemically brightened and anodised). Wooden surfaces are piano-lacquered.
