Since childhood I was fascinated by science fiction movies. They are the true source of ideas and inspiration, help to think abstractly, exceed the limits of imagination and technological possibilities and break the rigid frames of reality. It is very useful during designing. Many movies of this genre play in my life a special role. Their incredible scenery and beautiful music are my inspiration.
And just like that – special – is also for me the Proxima. Since the first version was built six years ago, I spent a lot of time and attention to its design. New solutions and new technologies were elaborated especially for her and thanks to her. All these technologies were used later in other designs. Proxima has also evolved in sound. This time is no different.
Design of the first Proxima was inspired by mysterious monolith of S. Kubrick’s “2001: A Space Odyssey”. The inspiration for the latest version are soaring skyscrapers of future New York and wonderful creations created by Jean-Paul Gaultier for one of my favorite science-fiction movies – “The Fifth Element” by Luc Besson. In the movie, our planet was saved by four mysterious stones symbolizing the four elements: wind, fire, water and earth, and the beautiful and extraordinary woman “from the stars” was the fifth element. For me the 5 element on Earth is music. Let Proxima be this unique “fifth element”.
The Proxima cabinet forms a compact block. The main part of the structure consists of 5 layers: front & back walls and three frames made of MDF with different thickness. They form the inner part of the side, top and bottom walls, and are connected to each other by additional elements made of HDF. From the outside, sides and top are covered with an additional layer of MDF panels finished with leather. These elements have a double function: dampening of cabinet vibrations and are a decorative part of the unique Proxima design.
Loudspeaker proportions were defined very carefully – the ratio of height to width is not random and is chosen to make Proxima optically seem smaller than in reality, and despite its height of 120cm “does not dominate”, even in a small listening room. The individual driver’s have also been placed at the appropriate height not only for the best acoustic performance, but also to optically lower the center of gravity of the body, making it more stable.
With the use of multiple screws and mass damping, the panel thickness of 16mm has been fixed to the front wall. It is the support for the woofer and also the cover of the tweeter and TMI (Tweeter Multilayer Isolation) system. It is the most complicated part of the Proxima cabinet. To execute it from a single piece of MDF, 19 different cutters settings have been used and more than 50 different operations: milling, drilling and grinding have been executed.
The unusual shape of the decorative panel was created over many days by drawing and multiple “improving” each of the curves, matching the correct proportions to achieve the desired effect. Every detail has been drawn and made by hand, without using a computer. The convex crease that runs through the front and side panels recalls “sail in the wind” and complements the unique Proxima design.
The carefully executed cabinet shape with leather finishing components results in a slim, graceful loudspeaker of unusual finesse. It will certainly be a great addition for any room.
The front panel is complemented by speaker grilles fixed with neodymium magnets.
On the back of the cabinet, another panel covered with leather has been mounted. It is the basis for the gold speaker terminals and for the “magic eye” – the opening protected by thick acrylic plate, through which you can look inside and see high quality crossover system which controls Proxima.
Proxima stands on a multi-layered plinth covered in leather and equipped with four gilded spikes. The plinth also has Divine Acoustics laser-etched logo – also seen on the tweeter frame.
CRCdesign (Cabinet Resonance Control design) – is a combination of rigidity and vibration damping properties that significantly affects the final sound of the loudspeaker. All methods of connecting the various materials, assembly components and the complexity of the entire cabinet of the Proxima were evaluated. The CRCdesign was designed to ensure ideal enclosure-to-speaker integration and to minimize vibrations and parasitic resonances.
The Proxima is a two-way loudspeaker. Two carefully matched drivers precisely mated to the other to form a single “voice”. The resulting sound is both natural and accurate while also being immensely entertaining – and engaging. Natural tonality and eerie realism will be yours to savor upon every music selection played.
The woofer has a 17cm polypropylene diaphragm, a large vented magnet system, inverted rubber surround and die-cast basket precisely tuned to compensate for parasitic resonances that are created by diaphragm vibrations. This tuning – BAD (Basket Accurate Dampening) system – led to a significant reduction in distortion yielding the most accurate midrange free from coloration.
The tweeter chosen is the original Divine Acoustics’ model, that was created specifically for the Proxima. It was built on the basis of a light dome with a diameter of 28mm, prepared with rare woven silk. The voice-coil operates in the surrounding chamber, which reduces the dome’s resonance and air pressure generated around it. Ferrite magnet system resonances has been suppressed thanks to BAD system. Behind the magnet another chamber has been built. It is designed to control and suppress vibrations of the magnetic system. It is filled with a dampening mass – a combination of fractionated sand, saturated with oil.
The tweeter is responsible for reproducing the very delicate high frequency’s associated with music reproduction. Any structural vibration that reaches the tweeter will interfere with treble reproduction. Therefore, it is necessary to eliminate vibrations (transmitted through the cabinet) from reaching the tweeter. At Divine Acoustics, a proprietary TMI (Tweeter Multilayer Isolation) system has been designed to effectively isolate the tweeter from distortion-causing micro vibrations. The Proxima was the first loudspeaker in which TMI was applied. The tweeter is effectively isolated from the cabinet by utilizing a set of gaskets of different thickness, hardness and damping coefficients. Such a highly specific combination of materials significantly affects the “pacification” of the magnetic field oscillations thus improving the micro-signals response within the coil. Simply put, TMI system results in a very precise, natural, detailed and extended treble reproduction.
The amplifier sends a full-range signal to the loudspeaker. The loudspeaker crossover is responsible for dividing the signal and sending it to the appropriate driver. It’s the “brain” of the speaker, responsible in creating the final quality of sound. It’s by no means a simple endeavor. Designing the crossover for new Proxima took over one year. During this time, hundreds of hours of listening and weeks of burning-in between successive revisions of sound, 17 crossover components were painstakingly selected. They form a second order filter with auxiliary systems for phase and impedance corrections.
Proxima crossover utilize the excellent Jantzen Audio Z-Superior, Z-Standard and Cross-Cap capacitors that are used in configurations selected during long listening sessions, without use of any computer software. Specially designed crossover filter system allows to use the RFpath (Resistors Free path) system – the complete elimination of using a voltage divider resistor for the tweeter. The result is an extremely transparent, open and detailed sound, rich in micro-signals in the upper midrange and treble. At the same time a balance between all tonal ranges has been assured. Thanks to the new crossover, the dynamics, power and overall integration of sound throughout the entire frequency spectrum, authenticity of rhythm and recording atmosphere has been significantly improved.
All crossover components are paired with a truly laboratory accuracy. OFC coils are made with the utmost attention to repeatability, carefully weighed and measured. The elements are mounted on a plate coated with a damping material and connected to each other directly to ensure the optimal driving signal path. Geometric layout of the components on the board is subjected to the SGP system – a Single Ground Point for the entire electrical system. To keep the overall repeatability and the highest quality of hand-mounted crossovers, more than 30 measurement points have been selected along with additional tests that must be executed for select components.
The signal is fed to the crossover using strips of OFC copper, to the woofer is flowing through the litz cable cross-section 2.5 mm2, and the tweeter is powered by an R-core cables with pure OFC copper with a diameter of 0.85 mm2.
Proxima is the stereo floor-standing speaker suitable for listening rooms of 12 to 30 square meters. It is designed to sound great with high quality solid-state or vacuum tube amplification from 2-90 watts-per-channel.
Speakers run-in time:
Before speakers sound their best, between 100 and 500 hours of operating use is required. The time variation is a result of the amplifier type used. During the “break-in” time, coils, suspensions of tansducers and crossover elements will optimize and adapt to the amplifier.
After that time, sound of the speakers should be smoother and more natural. Speakers will also need a few run-in hours after non-operating period (several weeks) or connecting to another amplifier.
GRAVITY Vibrations Absorbing Platform has been created to work with the CD, DVD, Blue Ray players, amplifiers (especially tube) and turntables. Units placed on the GRAVITY gain in dynamic and have more open and natural sound. It also improves bass reproduction and location of the virtual sources in space.
GRAVITY functions as a buffer. It separates a device which is placed on it from the ground. It prevents spreading of vibration from the ground into the device. What is more, the platform cumulates and suppresses vibrations which are produced by the device. In this way, it restores and ensures proper and comfortable working conditions.
