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. Meet the new improved version from 10W650A-4

  • New basket design implemented, reducing its size from 4.33″ to 3.90″ of mounting depth
  • Improvement on output throughout + 1dB on the low frequency frequency response
  • Gain on the vocal response from 350 Hz to 4000 Hz
  • Increased on voice coil winding has improved power handle and raised its Xmax to 5.72 mm

The purpose to built this midrange was to increase vocal response where the 10W650A-4 lack output without losing any midbass.

All new features on the  10MR650A make it capable of high output and low distortion, this mid range is perfect for filling in the important midrange response in any high output sound system. Great Addition to the ALTO Series!

  • 2.5″ layer CCAW voice coil wound on a glass fiber former, 4 Ohm
  • Vented pole piece dissipates excess heat to minimize power compression
  • 650 Watts Program RMS power makes high acoustical output
  • 80 to 6,500 Hz frequency response makes this great midrange with low midbass response
  • Covers the majority of the vocal range allow easy system integration with a tweeter
  • Also available at 8 Ohm – 10MR650A

The new 10MR650A-4 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 3.90” of mounting depth.

This midrange speaker is optimized for custom car audio applications to perform best in very small enclosures. It works excellently as a door speaker in car audio applications or as a low frequency mid for 2-way stuntwall systems.

Popular Combination with the 10MR650A-4 on custom doors is the WG175Py-Nd-4 Mini Mids and Highs compression horn driver – Combining 1 Horn driver per 1 Speaker, all tuned with our digital sound processor to easily blend them together with the following settings:

10MR650A-4 – High Pass Filter HPF 120 Hz at BT18 Filter to Low Pass Filter LPF 2200 Hz at BT12, following the compression driver from 1600Hz all way to 20,000Hz

Recommended system package 4x 10MR650A-4 + 4x WG175Py-Nd-4
Recommended Amplifier for 4x 10MR650A wired in parallel – QS3000 at 1 Ohm
