PRODUCT DESCRIPTION
- The Visaton BF 45 S - 4 Ohm is a compact fullrange loudspeaker with a diameter of only 4.5 cm, equipped with a black aluminium diaphragm and a transparent plastic basket. This small powerhouse delivers a balanced frequency response from 90 to 20,000 Hz, so that both music and speech sound detailed and clear, even in compact installations. The BF 45 S is suitable for applications where limited space and good sound must go hand in hand, such as in narrow designs or discreet sound solutions. With a rated power of 4 watts, peak power of 8 watts and a sensitivity of 79 dB (1 W/1 m), this speaker can do a surprising amount in a small package.
