BF 37 - 8 Ohm

Art. No. 2261

3.7 cm (1.5") fullrange speaker with a wide and balanced frequency response and very good low range reproduction. With powerful Neodymium driver and high membrane excursion limit, optimized for small vented enclosures/enclosures with passive radiator. Suitable for applications where slim construction and good music and speech reproduction are requested.

*) IP protection class for front side when built into a sealed enclosure (gluing of the loudspeaker might be necessary)

Typical applications
Flat TVs
Info terminals
other compact devices speech and music reproduction
