PRV Audio 12MB1000FT-4 12" MIDBASS LOUDSPEAKER
DESCRIPTION
- Product Overview
Features
For high output speaker systems, PRV Audio’s 12MB1000FT 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 the 12MB1000FT makes it one impressive driver. With 97.5 dB efficiency and 1000 watts power handling this mid bass will be It is ideally used in car audio systems, making it easier to match a car audio amplifier to only 2 or 4 speakers wired in parallel. The smooth response from 70 to 3,200 Hz is perfect for 2 or 3-way designs.
Installation tips:
2x 12MB1000FT-4 wired in parallel to a SQ3500X at 2 Ohm
4x 12MB1000FT-4 wired in parallel to a SQ6000X at 1 Ohm
Tuned with PRV DSP at HPF 100Hz at BT18 / LPF 3000Hz at BT18
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 is used with a very precise machined top and bottom plate. The additional dual forced vent in the back plate for the coil allows this driver to handle up to 1000 Watts RMS without issue.
Featuring a paper cone has a special high strength paper pulp composition designed to achieve the best possible linearity within the middle frequency range and a special cone treatment specifically dedicated to improve the dampening properties of the moving assembly, thus considerably improving the smooth frequency response.
The voice coil is wound on a 3″ glass fiber with aluminum wire keeping weight to a minimum for incredibly quick transient response. Engineered with 17.5 mm of winding depth, this inside/outside voice coil provides excellent thermal and mechanical durability.
