BEYMA WL4Fe/N GUIA ONDAS WL-4Fe/N 8 OH
PM4
This speaker has PM4 technology
The new PM4 diaphragm, incorporates a new high tech polymer never used in audio before.
Delivers a stronger joint between the dome and the former of the voice coil and so a better behaviour with high power handling and long periods of working.
In the subjective field, which is also a relevant part in the Beyma development process, in our opinion it brings a more natural sound when comparing it with other polyesters
