PRV Audio’s Alto Series loudspeakers were carefully crafted to reproduce a natural, smooth sound while remaining dynamic. To get superior fidelity, the special composite cone is built with non-pressed paper for a reduced break-up, delivering a smooth frequency response and a low moving mass, increasing the efficiency of the speaker.
