Features

For high output speaker systems, PRV Audio’s 12MB1000FT-4 mid bass is an excellent option capable of amazing performance. A great new addition to the Forte Series, where more power handling and less distortion on mid low mid bass frequencies is the key.

All this attention to detail in the 12MB1000FT-4 makes it one impressive driver. With 97.5 dB efficiency and 1000 watts of continuous program power (RMS), this mid bass is ideally suited for car audio systems, making it easier to match a car audio amplifier to only 2 or 4 speakers wired in parallel. Also, its smooth response from 70 to 3,200 Hz makes it perfect for 2 or 3-way designs.

Installation tips:

Highlights

  • 3″ Inside/Out aluminum voice coil wound on fiberglass former for hi-temp performance, 4 Ohm
  • Ventilated voice coil gap reduces power compression
  • High Xmax for more Mid bass output
  • 1,000 watts continuous program power rating makes high acoustical output
  • Excellent performance in 2-way or 3-way systems
  • Weather-resistant paper cone and dust cap
  • Also Available at 8 Ohm

A rigid cast aluminum frame with narrow spokes to minimize reflections back into the cone. In addition, the frame includes force cooling system openings which allows airflow to cool the voice coil.

To drive the voice coil, a large ferrite magnet with a very precise machined top and bottom plate has been used. The additional dual forced vent in the back plate of the coil allows this driver to handle up to 1000 watts RMS without issue.


Features a special high strength pulp composition paper cone designed to achieve the best possible linearity within the middle frequency range, which, together with a protective cone treatment dedicated to enhancing the dampening properties of the moving assembly, considerably improves its smooth frequency response.


The voice coil is wound on a 3″ glass fiber with aluminum wire, keeping weight to a minimum for an incredibly quick transient response. Engineered with 17.5 mm of winding depth, this inside/outside voice coil provides excellent thermal and mechanical durability.

*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.
