A real fullrange made in France, and in a traditional way. Acoustic Service introduces you to the versatile 21 cm wide band.
The neodymium and ferrite hybrid magnetic system produces a powerful and controlled magnetic field. The membrane is treated 6 times to obtain good linearity with no distortion.
The specially treated paper bicone also makes it possible to reproduce the acute band accurately and precisely. The anti-vortex warhead substantially improves directivity by avoiding the phenomenon of compression.
Ventilated aluminum frame, anti-vortex warheads, gold-plated connectors, membranes and bi-cones made of "all-paper" cellulose fiber, coated peripheral suspensions, coils made of copper-plated aluminum wire (CCAW) symmetrically with respect to the support (inter-external winding) make these products a range that will seduce, most certainly, most of the most incredulous users of the concept "broadband".
Attention for the suggested cabinet (presented in the datasheet): Provide a 20x20mm stiffeners at mid-height, connecting the front and bottom, and a second connecting the two side walls. You can add a base.
