To deliver a maximum realistic scenery, the S5 is not just a usual dipole speaker. The S5 is very unique and let you have three options for adjustment: Front firing, Dipole and Dipole 3X (Both Dipole and front firing sound mode) The lower frequencies are very important for an accurate dipole reproduction and thus the S5 is equipped with two broad-band drivers on the sides. These drivers can be operated in different ways to ensure you enjoy the perfect surround feeling, producing a perfect combination of accurate and spacious sound. The Dual-Tweeter array on the front can handle high sound pressure levels while consistently producing crystal clear, detailed sound. It is supported by a high-class mid-bass driver which ensures the highest accuracy. Lean back and enjoy the rich, dynamic and yet wide sound of this incomparable surround speaker.
