Spirit 8 is a perfect choice as center speaker in high class multichannel setups. During the development, special attention was paid to the voice reproduction and an optimized dispersion pattern. Both factors are of fundamental importance for homogeneous and natural surround sound. The optimization was done by adding a waveguide to the silk dome tweeter and by spending huge effort on the development of the frequency crossover. The customized drivers fit ideal to all other speakers of the spirit series and provide highest dynamics and accuracy. Thus Spirit 8 is predestined for an immersive home cinema experience.
The 25mm silk dome tweeter originates from own development and is optimized in dispersion pattern and distortion by the use of a waveguide. By increasing the efficiency, it is possible to achieve very high SPL with Spirit 8 but also play extremely clean and detailed at lower SPL. The 6 1/2" mid/bass drivers contribute to the excellente voice reproduction due to their outstanding stiffness-weight ratio which is achieved by using a c-cone-sandwich membrane. The magnetic system behind the drivers is completely linear and enables the drivers to act with high deflections.
The backside of Spirit 8 offers several possibilities to adjust the sound to the room acoustics and your personal preferences. The jumper at the speaker terminal can be used to adjust the tweeter level which is very helpful in modern reverberant surroundings. Furthermore it is possible to alter the basic characteristics of the speaker by using the attached plugs to close both or only one bass reflex port. If you place the speaker near a wall, this possibility helps to optimize the sound.
Besides the strong magnets of the drivers, the high weight of Spirit 8 originates from the massive cabinet construction. The front baffle is 25mm thick, the side walls 18mm. Both are made from MDF which provides a strong internal daming. Additional stiffeners ensure minimum resonances together with the special damping material which is used inside the cabinet. Thus Spirit 8 can also reproduce deepest bass without loss of precision or accuracy.
The ornate polished multilayer paint makes Spirit 8 an absolute highlight and gives the center speaker a high-class look. The finish is available in matte black and matte white to ensure a perfect integration into your living area. The colours even benefit the modern design of Spirit 8.
The gold plated screw terminal guarantees an optimum lock for your speaker cables. Thus a safe connection and best signal transmission can be ensured. In addition the terminal contains the jumper for the adjustment of the tweeter.
The tweeter of the Spirit series is a 25mm silk dome which has already proven its great abilities concerning its power handling and impulse response. It is driven by a high performance magnet system to optimize the sensitivity, dynamics and power handling. The cooling is provided by a low viscosity ferro fluid and a high power alloy voice coil made of aluminum and copper. Due to the waveguide technology the relative SPL capacity and sensitivity increases which leads to a minimized distortion both in high and low playback volume. The waveguide helps further to balance the dispersion in a perfect way to give a similar sound character independent of the angle. Furthermore, the waveguide allows a lower crossover frequency which makes the dispersion pattern of the mid/bass driver match the pattern of the tweeter. Thus, the overall dispersion is perfectly balanced and controlled. The dome itself has a built-in protection against damages and finds back to its original shape after a gentle push. To ensure a stiff and stable connection to the cabinet, the front is made out of 5mm thick massive aluminium covered with rubber to dampen resonances.
The mid/bass driver originates our own development laboratory and is customized to fit the Spirit speakers perfectly. Its membrane consists of acrylonitrile butadiene styrene (ABS) and a long fiber pulp mixture in a special sandwich construction to even further increase its stiffness. Due to the lightweight materials, the cone provides an extraordinary stiffness-weight ratio and reduces resonances effectively. The spider is made of a mixture of cotton with nomex fiber. To ensure a nearly perfect impulse response, a specially developed and extremely strong magnet system is used. Its linearity provides a long stroke without compression and enables the speaker to handle a wide frequency range. Thus, the speaker can perform any stroke with highest accuracy. The voicecoil wire is made of a high temperature alloy of aluminium and copper to ensure an effective heat dissipation. To further avoid any edge resonances, a specially customized butylrubber surround is used.
The ornate frequency crossover ensures a perfect transition between the drivers. Thus the frequency crossover as well as the phase transition are optimized to provide maximum listening pleasure.The waveguide let us choose a relaitive low crossoverfrequency and this makes the dispertion very controlled. The high class capacitors and low impedance coils ensure a perfect signal transmission. To further minimize any unintended influences, the internal cables consist of high purity copper which reduces the transmission resistance.
Since every room is unique from an acoustical point of view, the speakers of the Spirit series are equipped with several room tuning possibilities. The bassreflex ports on the backside can be closed with the attached plugs which alters the basic characteristics of the speaker. It is for example possible to place the speakers near a wall and drive them in closed mode to compensate the bass increase due to the walls. Furthermore there is a jumper located at the terminal of the speaker which can be used to adjust the tweeter level to the prevailing acoustics and the personal preferences.
