PRV Audio’s 8MB700FT Forte Series was specially tailored to give you more power handling and less distortion. The larger voice coil ensures high heat dissipation and the necessary Bl to deliver high sensitivity even at high power with the minimum distortion.

The lower Qts allows more precise midbass. Superior fidelity is achieved through a perfect combination of a non-pressed cone with a smooth frequency response and its well ventilated magnet motor specially designed to allow high displacement without increasing distortion.

  • 2.5″ Voice Coil – More power handling and less distortion on mid low midbass frequencies
  • Ventilated voice coil gap reduces power compression
  • 8″ PRO audio Midbass speaker designed for Low Frequencies at High Power – 8 Ohm
  • 700 watts RMS program power gives capability of high acoustical output
  • More compact stronger neodymium version available 8MB700FT-NDY

To get superior fidelity, the special composite cone is built with non-pressed paper for reduced break-up, delivering a smooth frequency response and a low moving mass, increasing the efficiency of the speaker.

This 8″ is a great midbass option for pro audio systems or high SPL automotive systems, where extremely high output is required.

This midbass will stand up to years of serious professional use! Thanks to its special composed spider reduces distortion at a high excursion and double roll surround keep cone travel linear at high excursion.The 8MB700FT is an extremely efficient 8″ midbass from PRV Audio. Due to its wide frequency band and 97 dB sensitivity rating, this speaker is ideal for pairing with compression drivers, on 3-Way system, when used with recommended HPF using PRV Digital Signal Processor DSP

  • 95 Hz at 12 dB per octave filter Crossover / BT12
  • 85 Hz at 18 dB per octave filter Crossover / BT18

The large 2.5″ voice coil allows for the high 700 watts power handling and warrants the outstanding cooling system implemented into the motor.

Engineered with 11 mm of winding depth, this inside/outside voice coil provides excellent thermal and mechanical durability.

Technical Details


*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 provide 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.
