The Spirit 4 is a very flexible and versatile bookshelf speaker, which can be either used as an excellent stereo setup, with pinpoint imaging and wide soundstage, or integrated into a thrilling surround system. As the Spirit 4 uses the same tweeter and mid/bass driver as the Spirit 11, sonically, it is a perfect match and able to perform with precision and accuracy. Despite the compact size of its cabinet, the deep bass qualities are astonishing. The implementation in a stereo system is recommended in rooms where powerful and dynamic sound is desired, but where there is not enough space for larger speakers.
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 Tweeter, which is used for Spirit 4 is a 25 mm silk dome which has been developed and adjusted especially for this application over years. It has been designed together with its waveguide to achieve a perfect match concerning precision and dynamics. The XTZ developed mid/bass driver, a customized long-stroke woofer is used which has proven its capabilities concerning the reproduction of deep yet articulate bass. It harmonizes perfectly with the tweeter, leading to a natural and balanced sound.
On the Rear Panel of the Spirit 4, 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 port on the Rear Panel, with the attached plug, 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 4 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 utilized, hence the weight of 6.8kg per speaker. So the Spirit 4 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 4 looks as refined as it sounds.
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 detachable grille protects the drivers from dust and also from possible damage. To ensure perfect sound transmission, the grille is Acoustically Transparent and does not have any influence on the sound of the speaker.
