Meridian Product Brochure on-line MERIDIAN DSP LOUDSPEAKERS “Smart Art” is how one owner, an antiques dealer, describes Meridian DSP Loudspeakers. Their clean, classic lines blend into any decor, and belie the fact that these slim columns house the world’s most advanced loudspeaker systems. The DSP8000, our new reference model, is an unmatched technical tour de force comprising eight custom drivers, five power amplifiers, three digital crossovers, three D/A converters, and advanced distortion-cancelling computers – all within that elegant exterior. The drivers are integrated using digital filters which, in addition to ensuring great precision, allow crossovers that are impossible to mimic using analogue circuits. The linear-phase midrange/treble crossovers used in all our DSP models, banish the phase distortion other speakers routinely introduce within the ear’s most sensitive frequency range. The benefit is three-dimensional imaging, in stereo or surround modes, no conventional hi-fi system can match. Meridian DSP loudspeakers are breathtaking in their ability to bring believable music making into your room, with even subtle body movements of the musicians clearly audible, such as a singer swaying or an instrumentalist stepping up for a solo. Voice and instrument timbre are utterly natural. Highs are smooth and sweet. Music sounds balanced and articulate, with clarity and detail retained even at low volumes. And our DSP loudspeakers are easily muscular enough to reproduce an orchestra or rock band at realistic volume levels. Our DSP loudspeakers also offer control features beyond the imagining of conventional loudspeaker manufacturers. All of which can be accessed via remote control, from your favoured listening position. |

How do Meridian DSP Loudspeakers Work? Conventional passive loudspeakers are technically sub-optimal in a number of important respects. Conventional power amplifiers, because they must be designed to drive a wide range of loudspeaker loads, are over-engineered for many circumstances in which they will be used. The combined result? Compromise, redundancy and lack of balance. At Meridian we think differently – and have done since our very first active loudspeaker, the M1, was introduced in 1977. If a loudspeaker contains its own dedicated power amplifiers, low-level electronic crossovers and power supply, many advantages accrue. It’s like building a car with engine and transmission rather than without! Benefits include deeper bass from a smaller cabinet, natural dynamics, perfect matching of the amplifiers to the drive units, greater versatility in crossover design and no ugly speaker cabling. With the introduction of our first DSP (digital signal processing) model in 1991, the active loudspeaker concept was advanced still further. Keeping the signal in digital form until as late as possible in the signal path minimizes noise and distortion. It also allows crossover filtering, correction and numerous other functions to be performed in the digital domain, offering unprecedented signal processing and control possibilities. The picture (right) of the back panel of the DSP6000 illustrates typical key components inside every Meridian DSP Loudspeaker. A dedicated high performance engine and transmission already fitted! |

DSP8000 REFERENCE LOUDSPEAKER SYSTEM This beautiful system represents the fruits of more than 25 years continuous development of loudspeakers as musical instruments. The finest materials and state of the art design combine to create what we believe is the ultimate home loudspeaker. Every curve has a purpose, every dimension a meaning. Nothing can prepare you for the natural, tactile sound it makes. A four-way DSP active loudspeaker, the DSP8000 can be used as a stereo pair or within a multichannel system of up to seven channels. It can be mixed with other Meridian DSP and Active loudspeakers to provide the optimal solution for any room and budget. The head assembly, which contains the custom treble and midrange drivers, is a sealed enclosure fabricated from curved pressure-laminated panels – each using multiple layers of selected woods and metal to provide high stiffness and damping. The drive units are clamped with machined rings that combine a smooth acoustic surface with high rigidity. Supported on three machined feet atop the bass enclosure, the head is at the correct height for a seated listener, while its narrow, tapered shape offers optimum dispersion across a wide listening area. Like the head, the bass cabinet is constructed from interlaminated panels with extensive bracing. Six long-throw, horizontally opposed drive units are clamped together to free the cabinet from vibration, even at full power. The front panel is 6mm glass and incorporates a window for the matrix display and infrared remote control sensor. The cabinet stands on triangulated adjustable machined foot assemblies with provision for floor spikes or skids. At the cabinet rear is the electronic heart of the system. Here five fast, low-feedback power amplifiers are mounted on a multi-finned extruded heat sink. The tweeter and mid each have a customized amplifier and three more power the bass system. Also mounted to this panel are the computer and DSP chips, which operate using powerful Meridian-developed software. All connections are made to the lower rear of the cabinet. DSP8000 System Design: Four-way active loudspeaker. Crossovers at 80Hz, 200Hz and 2.6kHz. Four 24-bit D/A converters. Three 150W and two 100W power amplifiers per speaker. All processing is performed upsampled in twin 100MHz digital signal processors (DSPs). DSP8000 uses Meridian’s memory-based dejittering system for ultimate clarity. Controls: System and speaker are operated with the included Meridian System Remote. Control features include source, bass and treble tilt, listening axis, volume, time-compensated balance and absolute phase. Inputs: Two coaxial digital audio, 32kHz to 192kHz at up to 24 bit. MHR support. Response: 20Hz to 20kHz. Max. output 118dB spl. Display: Eight-character dot matrix display behind front glass, can be blank. Dimensions: 1350mm (53.2in) H, 400 (15.7) W, 528 (20.8) D. Finish: Black gloss piano lacquer head unit and black piano lacquer and glass bass cabinet. Other colours special order.

DSP6000 AND 6000C DIGITAL LOUDSPEAKERS Until the introduction of the remarkable DSP8000, the award-winning DSP6000 was our flagship loudspeaker product. Proven in audiophile systems worldwide and the subject of numerous rave press reviews, it remains a formidable transducer. Overall design and layout are similar to that of the DSP8000, the main differences being in bass cabinet construction and drive unit complement. The head assemblies are of handed construction, with a symmetrical version available for centre channel use (6000C). Of course, the DSP6000 has all the signal processing and control features of our other DSP loudspeakers and can be matched with them in a mixed system. DSP6000 System Design: Three-way active loudspeaker. DSP crossovers at 200Hz and 2.6kHz. Three channels of delta-sigma D/A conversion. Four 75W power amplifiers per channel. All processing is performed in the 100MHz digital signal processor (DSP). Controls: System and speaker are operated with the included Meridian System Remote. The listener has complete control over the input source and features including bass and treble tilt, listening axis, volume, time-compensated balance and absolute phase. Inputs: Two coaxial digital audio, 32kHz to 96kHz at up to 24 bit. MHR support. Response: 20Hz to 20kHz. Max. output 114dB spl. Display: Matrix display behind front glass, can be blank.

DSP5500 DIGITAL LOUDSPEAKER This model – ideal for home theatre – is a superb front-facing three-way speaker that can be built into system cabinets. Its software adjusts performance for location. Heavy steel shields the speaker from TVs and provides an extremely rigid enclosure, for clear midrange, startling dynamics and tight, visceral bass slam down to a true 30Hz. The 5500 employs exotic silver voice-coil tweeters and the latest digital-to- analogue conversion like its brothers. Four 75-watt built-in amplifiers per speaker operate in active mode, delivering far more dynamics than passive designs of the same power. Computers blend its woofers and tweeters for perfect phase and remarkable imaging. Like its brothers, the 5500 is remote-controlled and displays its functions on the front, showing either volume, music selection or blank. On-board computers offer full bass, treble, absolute phase and a variety of other system commands. The balance control not only changes the relative volume of the two speakers, but also delays the sound from the speaker closest to you, so that all sounds reach your ear at the same time. Similarly, you can steer the image up and down for optimum listening: standing, sitting, or reclining on the floor. |
