Features
PRV Audio’s 8MB700FT-NDY-4 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 on high power with the minimum distortion.
The lower Qts allows for more precise mid-bass. Superior fidelity is achieved through a perfect combination of a non-pressed cone with a smooth frequency response and a surrounding ring specially designed to allow high displacement without increasing the distortion.

Highlights
- Nominal Impedance: 4 Ohms
- Rated AES Power Handling (RMS): 350 Watts
- Program Power: 700 Watts
- Sensitivity (1W/1m): 98 dB
- Voice Coil Diameter: 2.5″ (51 mm)
- Also Available at 8 Ohm

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

The 8MB700FT-NDY-4 is an extremely efficient 8″ mid-bass from PRV Audio. This driver is perfect for mating to compression drivers due to its wide frequency bandwidth and its high 98 dB sensitivity rating, on a 3-way system (with a suggested 95 Hz, 12 dB/octave high pass filter in place)!
Its powerful optimized neodymium motor is vented to provide excellent cooling.

The large 2.5″ voice coil allows for the high 350-watts power handling and warrants the outstanding cooling system implemented into the motor.
The high sensitivity rating of 98 dB 1W/1M makes it capable of generating a lot of output!

*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.
