Outstanding performance in home cinema, thrilling in stereo operation - Spirit 11 convinces with high class components and advanced technologies in every disciplin. The tweeter is a 25mm silk dome in waveguide execution to retain maximum precision at highest SPL. The mid/bass drivers originate from the own laboratory and are perfectly customized for operation in the cabinet together with the tweeter. The dynamics which this combination is able to deliver is second to none and reaches from the deepest bass to the finest heights. Impulses are reproduced accurately and provide for goose bumps for music and film enjoyment.
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 the 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 class drivers maintain control even when stroking ultra long which provides a punchy and accurate bass.
On the backside of the Spirit 11, there is a jumper located which allows to adjust the tweeter level to the prevailing room acoustics or your personal preference. Furthermore, it is possible to close the bassreflex ports on the backside with the attached plugs to change the basic characteristics of the speaker. For example, if both ports are closed, the speaker plays less deep in the bass which helps when the speaker has to be placed near a wall.
The cabinet of the Spirit 11 is equipped with a 25mm strong front wall and 18mm strong side walls, both made from MDF. Together with the additional stiffeners, this solid construction adds up to the high weight and the massive impression of the speaker. To further minimize the already reduced internal resonances, a plentiful amount of damping material is brought in. So the Spirit 11 plays also deepest bass always with highest precision.
The applied multilayer paint is ornately polished and ensures an excellent quality impression. In matte black as well as matte white, the Spirit 11 definitely shows 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 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 pluggable cover protects the drivers on the one hand from dust and on the other from possible damage. To ensure perfect sound transmisssion, the cover is sound transparent and does not have any influence on the sound of the speaker.
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.
