INTRODUCTION

The landscape for High End Audio has been changing for a number of years now, and the shift has been accelerating, with no signs of it slowing down. We refer to of course, the choice of convenience.

This ‘convenience’ has emerged in many shapes and forms, driven by the lure of ease of use, getting started and installation. These factors have begun to triumph over high-quality audio, with music lovers settling for lesser sound quality in order to get more convenience. This is not to say that good sound is not important to them, but simply because the wish for convenience left them with no alternative.

The trend is that rst time buyers of high-end audio have little interest in the hassle with cables and multiple boxes of electronics. They want easy access to all their digitally stored music, be it online, on their phone or on a network connected hard drive - but they want it to sound great. In short, they long for the virtues of a traditional Hi-Fi product that matches the audio demands of the 21th century.

DALI is truly proud to introduce the CALLISTO series - a contemporary take on traditional Hi-Fi.

The DALI CALLISTO systems consist of two stereo speaker con gurations and an optional central Sound Hub. 

CALLISTO SPEAKERS

The CALLISTO speaker series presents a unique opportunity for DALI to deliver the best of both worlds. Controlling the development of everything from the drivers to the amplifer, we can optimise every single component to match each other perfectly. This enables us to design the woofers to be more linear than would ever be possible in a similar priced traditional passive speaker system. Pushing the woofer design to new limits of performance is possible because we are in total control of the signal path, and can therefore ensure the control needed so not to overextend the drivers. Leveraging this potential, we elevated the audio performance to levels that surpass almost any speaker amplifer combinations in this price bracket. 

CALLISTO 2 C

This is the compact stand mount solution in the CALLISTO system. Perfect for smaller spaces or rooms where the speakers’ presence must be minimised, without giving up on performance. The combination of the 61⁄2” low-loss wood bre woofer, the hybrid tweeter module and the perfectly balanced internal volume of the cabinet, come together to form the base of a highly accurate audio experience. 

CABINET

When preparing the visual design for the CALLISTO series we especially had two things in mind. We were seeking a design that would allow for the introduction of the hybrid tweeter in the stand mount model, and a look that clearly showed that this series is something new, without losing the connection to the traditions of the passive speaker. With the use of a round front housing for the ribbon tweeter in combination with the distinctive tweeter front plate, and the elegant integration of the volume control and LED’s, we believe that we succeeded, and then some!

Manufacturing the cabinet at our large and ef cient woodworking facility in Denmark, we can keep complete control over the quality of the speaker, handling everything from cutting out the Medium Density Fibre board (MDF) cabinet to applying the vinyl. The mounting of the drivers and the nal tests and approvals on each and every speaker is also handled directly at our own assembly lines in our Danish factory.

Constructed from 25mm MDF, the cabinets employ a very
rigid construction with solid bracings across the inside of the cabinet for extra reinforcement. Together with the very solid MDF structure, this contributes to a stiffness and density that practically eliminates resonance within the cabinet. However, excessive internal bracing can disturb and hinder the crucial air ow inside a speaker cabinet, thereby adversely affecting sound quality. Therefore, great care is taken in the layout and application of internal bracing in order not to reduce the internal volume of the cabinet unnecessarily.

The high-grade vinyl is carefully selected among the nest available. Extensive testing is carried out to make sure that the surface and joints of the cabinet will stand the test of time. Through strict in-house control of every aspect of production, CALLISTO achieves a level of t and nish typically found only in products well beyond its price point 

WOOFER

We knew from the outset that the woofer for the CALLISTO series would be something unique. Never before has the entire audio chain been in the hand of DALI’s own R&D team. This intimate knowledge helped our acoustic team design and build a woofer that took low loss and linearity to a whole new level.

Working with well known elements from the OPTICON and RUBICON woofers, we used advanced computer simulation and a whole lot of listening hours, to optimise the magnet motor to deliver the ultimate in ux saturation and Bl linearity within the voice coils excursion span. The rear membrane suspension (spider) geometry was likewise optimised to work in close harmony with the ampli er. Knowing that we controlled the maximum signal impulse, we could soften up the spider and obtain a very linear and perfectly symmetrical suspension within the working area of the voice coil and membrane, only taking control and slowing down the membrane movement at the outer most excursion points.

The extra linearity obtained both around the voice-coil and in the spider manifests itself in reduction in mechan- ical distortion and less strain on the ampli er, which leads to more detailing and a better de ned sound stage.

The CALLISTO woofers also bene ts from the use of SMC in the pole piece. Soft Magnetic Compound (SMC) is a coated magnet granule that can be shaped into any form that you would want. SMC has many advantages, and when used in a speaker magnet motor system, it results in a signi cant reduction of distortion from mechanical loss. SMC’s unique ability to deliver a high magnetic conductivity and a very low electrical conductivity delivers all the wanted qualities of a really good speaker magnet without the traditional downsides.
