Sophisticated design with very high-quality material for a pleasant and long-lasting wear. Deep bass is achieved by the Bass Reflex speaker. Not a single bass: a thin ceramic driver and an aerospace driver absorbs the listener into the world of surround music. Impedance 32ohm with audio frequency range 20-40000Hz.

3 Drivers bear fruit.

Dynamic driver with bass reflex for tighter low frequencies.

Description of 3 drivers:

1. Low frequency driver. The new Bass Reflex driver with bass reflex allows you to experience deep and thick bass. Bass reflex driver, different from classic speaker design, the fact that the former goes more into the low-end range, which leads to a double reflection of the generated energy, converting it into a dense and deep low-frequency range.
2. Medium frequency speaker. Dynamic midrange driver with multilayer aerospace composite diaphragm with metal diaphragm for spacious, clear, and overall balanced sound.
3. High-frequency driver. When operated, the thin ceramic driver results in detailed high frequencies up to 40kHz. As the manufacturer assures, it also creates the effect of a concert hall and silky high frequencies.
