The 25mm silk dome tweeter was customized for the Spirit-series and thus fits perfectly with the mid/bass drivers. The Tweeter has been designed to optimize its dispersion pattern and efficiency.
The XTZ developed mid/bass driver, a customized long-stroke woofer, has proven its capabilities for the reproduction of deep yet articulate bass. It harmonizes perfectly with the tweeter, leading to a natural and balanced sound.
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 tweeter output level can be adjusted to the prevailing room acoustics, or your personal preference.
The bass reflex port can be closed to 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. 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.
