Features

PRV Audio’s ALTO Series were carefully crafted and voiced to reproduce a natural, smooth sound while remaining dynamic. To get superior fidelity, a special composite cone is used to smooth frequency response and to keep the moving mass low, increasing the efficiency.

All 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.

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 improved power handle giving it 450 watts RMS
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 8MR450A from ALTO Series has everything you want in a midrange pro audio loudspeaker, without sacrificing performance we have designed a compact and versatile footprint with only 3.21” of mounting depth.

The 1.5” 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 midrange speaker is purpose-built to cover from 100 Hz to 9,000 Hz in 3-way speakers ( subwoofer, mid & tweeter), works great as a door speaker in car audio applications.

PRV 8″ Midrange Speaker 8MR450A PRO Audio 450 Watts / 8 Ohm ALTO Series

4 Speakers – 1x QS2000 2 Ohm, 4 speakers in parallel
8 Speakers – 1x QS5000 1 Ohm, 8 speakers in parallel

Recommended HPF using PRV Digital Signal Processor DSP when using up to 450 Watts RMS musical power ( without clipping )

140 Hz at 12 dB per octave filter Crossover / BT12
125 Hz at 18 dB per octave filter Crossover / BT18

If you have compression drivers or super tweeters on your system the recommended LPF is 9,000 Hz at 18 dB per octave filter Crossover / BT18 but you may set it lower to blend in better depending on the other components in your system, or you may not use a LPF at low power to take advantage of its high frequency response.

^{*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.}
