Spirit 11 – Punchy, accurate and capable of highest SPL
Outstanding performance in home cinema, thrilling in stereo operation – Spirit 11 convinces with high quality components and advanced technologies in every aspect of its construction. The tweeter is a 25mm silk dome in waveguide execution to retain maximum precision at highest SPL. The Mid/Bass drivers originate from our own laboratory and are perfectly customized for operation in the cabinet together with the tweeter. The dynamic range, which this combination delivers is second to none and reaches from the deepest bass to the finest heights. Dynamics and Transient Peaks are reproduced accurately and provide for those goose bump moments, both for Music and Movie enjoyment.
Drivers
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 Quality Drive Units maintain control, even when at High Excursion, providing punchy and accurate bass.
Sound Tuning
On the Rear Panel of the Spirit 11, 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.
Cabinet
The cabinet of the Spirit 11 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 11 plays the deepest bass frequencies, always with precision and composure.
Surface
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 11 defines where the term “sound furniture”, originates from. The classic, yet modern construction contributes to the splendid aesthetics of this magnificent speaker.
Speaker Terminals
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.
Further Information
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 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.
Crossover
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.
Sound Tuning
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 terminals of the speaker, which can be used to adjust the tweeter level to the prevailing acoustics and personal preference.
