PRV AUDIO 8MR450A 8 Inch Midrange Speaker, 8 Ohms, 450 Watts
About the Product
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 used to smooth frequency response and to keep the moving mass low, increasing the efficiency.
- 2″ DUAL layer CCAW voice coil wound on a glass fiber former, 8 ohms
- Low inductance for great transients and extended high frequency response up to 9,500 Hz
- Large voice coil winding has improves power handle giving it 450 watts RMS continuous program power rating
- High sensitivity of 96 db makes this a great budget choice for high output home, car, and professional audio systems
- Full copper sleeve on the pole-piece for low distortion and inductance
