SKU: 8MR400A Category: Tag:


PRV Audio’s Alto Series were carefully crafted and voiced to reproduce a natural, smooth sound while remaining dynamic. To get the superior fidelity, a special composite cone is built with non-pressed paper (visible on the back side) for reduced break-up, smooth frequency response and to keep the moving mass low, increasing the efficiency.

The 8MR400A delivers outstanding vocal reproduction with high output. It provides extended frequency response and smooth sound with very low distortion. Handling up to 200 watt RMS and with 94 dB sensitivity this midrange will be right at home in any home, automotive, or professional high SPL design.

  • Rated AES Power Handling (RMS): 200 Watts
