SKU: 8MR450A Category: Tags: ,



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 midrange is perfect for filling in the important midrange response in any high output sound system. Great Addition to the ALTO Series!

  • 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

The new 8MR450A from ALTO Series has everything you want in a mid range pro audio loudspeaker, without sacrificing performance we have designed a compact and versatile footprint with only 3.21” of mounting depth.

The 38 mm (1.5 in) copper clad aluminum wire is wound in a double layer using a high temperature resin adhesive on a strong ventilated glass fiber former. Also, a copper sleeve is included on the pole piece which reduces inductance to improve the high frequency response.

A triple roll cloth surround, combined with an optimized fiber pressed paper cone, ensure the speaker’s frequency response is smooth and extended.

This professional midrange speaker is purpose-built to cover from 100 Hz to 6,000 Hz in three-way speakers, but also works great as a door speaker in car audio applications and a woofer in two-way satellite speaker concept.

*Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range. **Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation. ***Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
