Product Overview
About: PRV Audio 8MR450A 8" Midrange Loudspeaker - 8 Ohms (Sold Individually)
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. All new features on the 8MR450A make it capable of high output and low distortion, this mid range is perfect for filling in the important mid range response in any high output sound system.
Highlights:
- DUAL layer CCAW voice coil wound on a glass fiber former, 8 ohms
- Ventilated former to reduce power compression
- Low inductance for great transients and extended high frequency response up to 9,500 Hz
- 450 watts continuous program power rating
- Great budget choice for high output home, car, and professional audio systems
- Full copper sleeve on the pole-piece for low distortion and inductance
- The new improved version from 8MR400A
