This low-mid frequency transducer offers three main points of interest: a good sensitivity (98 dB), a controlled dispersion up to 3 kHz and a low harmonic distortion. These characteristics make it suitable for high quality sound reinforcement systems, especially for live applications. Furthermore, it is mounted with a cast aluminium basket that reduces mechanical vibrations and increases thermal dissipation. This fact, added to the use of a high quality 2" voice-coil, increases considerably the power handling reaching 250 w AES.

About Beyma
Since 1969 Beyma has been manufacturing extremely high-end speaker systems from its factory in Valencia. These products are create by some of the best audio engineers who enjoy good sounding music. Do not compare Beyma to other brands who import speakers from China. Beyma produce a wide range of solutions in the loudspeakers field. Their products are all underrated. You can amplify any of their speakers with 2 times the amount of the rated power, and they will easily handle all the power!
The accumulated experience as manufacturer of loudspeakers together with their famous Research & Development team have been the key to their success.
Beyma owns and maintains multiple show car vehicles. Their show cars actually use mostly the cheaper Beyma products in them. Their show cars are known to have the cleanest sound. They sound just as good from 200 feet away as if you were sitting in the car. That is the type of quality and engineering that goes into every Beyma product.
