For the NoBox 170, four high-grade WS 17 E - 4 Ohm bass drivers with paper diaphragms were selected that are optimised for free-air use. Due to the fact that they have no cabinet, they produce wonderfully clean low-frequency bass. Also, thanks to the dipole principle, they generate fewer standing waves, which means the bass tends to fade more quickly, so it can never become fuzzy and does not drone. On top of this, there is the WS 13 E - 8 Ohm mid-range driver that also features a paper diaphragm and a high quality standard, making it ideal for free air use.
Once correctly positioned and set up, the sound experience is fascinating: the NoBox 170 reproduces voices and instruments in the centre of the room with an airy lightness without artificially inflating them or shifting them laterally or in terms of depth. When seated in the middle of the listening space, the listener is treated to excellent clarity, but even in the seats right at the fringes of the space, the overall sound quality does not break up but remains faithful to its position and lively character in the room.
