Spirit 8 – Imposing dynamics and accurate Vocals for inspiring home cinema
Spirit 8 is a perfect choice as a Centre Speaker in High Class Multichannel Setups. During the development, special attention was paid to vocal reproduction and an optimized dispersion pattern. Both factors are of fundamental importance for homogeneous and natural surround sound, as reproduction of the Human Voice is primarily projected via the Centre Channel. The optimization was done by adding a waveguide to the silk dome tweeter and by spending huge effort on the development of the high quality crossover. The customized drivers are unique spirit series and provide a matching acoustic balance and sonic signature throughout the Frequency range to highest dynamics and accuracy. Thus Spirit 8 is a key element for creating an immersive home cinema experience.
The 25mm silk dome tweeter was customized for the Spirit-series and thus fits perfectly to the mid/bass drivers. Due to the waveguide technology, the dispersion pattern, as well as efficiency were optimized. The 6 1/2″ mid/bass drivers originate also from the XTZ development center and provide precision, even at highest SPL. These High Quality Drive Units contribute to the excellent vocal reproduction, due to their outstanding stiffness-weight ratio, which is achieved by using a c-cone-sandwich membrane, enabling the mid/bass drivers to maintain control, even when at High Excursion, providing punchy and accurate bass.
On the Rear Panel of the Spirit 8, there is a jumper, which allows adjustment of the tweeter output level to the prevailing room acoustics, or your personal preference. Furthermore, it is possible to close the bass reflex ports on the Rear Panel, with the attached plugs, which alter the Low Frequency characteristics of the speaker.
This enables placement of the speaker near a wall and drive it in sealed mode to compensate for the bass increase, due to the wall boundary effect.
The cabinet of the Spirit 8 is equipped with a 25mm front panel and 18mm side and rear panels, all made from MDF. Together with the additional internal bracing, this provides a very solid and inert cabinet construction, hence the high weight and the massive impression of the speaker. To further minimize the already reduced internal resonances, a large amount of internal damping material is also utilised. So the Spirit 8 plays the deepest bass frequencies, always with precision and composure.
The cabinets are painted with a perfectly finished multi-layer paint which make the speakers aesthetically appealing in a domestic environment.
In matt black as well as matt white, the Spirit 8 defines where the term “sound furniture”, originates from. The classic, yet modern construction contributes to the splendid aesthetics of this magnificent speaker.
The gold plated screw terminals guarantee an optimum connection 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 output level.
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 voice coil made of aluminum and copper alloy. Due to the waveguide technology, the relative SPL capability and sensitivity increases, which leads to a minimal distortion at all volume levels. The waveguide controls the dispersion of the Tweeter, to give a similar sound characteristic, independent of the listening 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 damage and reverts to its original shape after a gentle push (not recommended, but is a safety feature).
To ensure a mechanically rigid connection to the cabinet, the front waveguide is made of 5mm thick, solid aluminium, covered with rubber to dampen resonances.
Midrange / Woofer Driver
The Mid/Bass driver originates from 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 further increase its stiffness. Due to the lightweight materials, the cone provides an extraordinary stiffness-weight ratio and reduces resonances effectively.
The suspension 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, with highest accuracy.
The voice-coil is made of high temperature aluminium and copper alloy, to ensure effective heat dissipation and maintain linearity. To further avoid any edge resonances, a specially customized butyl-rubber surround is used.
The bespoke crossover ensures a perfect transition between the drive units.
The crossover frequencies, as well as the phase transition are optimized to provide maximum listening pleasure. The waveguide enables us to choose a relatively low crossover frequency point, hence giving very controlled high frequency dispersion characteristics.
The high quality capacitors and inductors ensure perfect signal transmission. To further minimize any unintended influences, the internal cables consist of high purity copper, which minimizes 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 bass reflex ports on the Rear Panel can be closed with the attached plugs, which alter the Low Frequency characteristics of the speaker.
This enables placement of the speaker near a wall and drive it in sealed mode to compensate for the bass increase due to the wall boundary effect.
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 personal preference.
