About: PRV Audio 8MB700FT-NDY 8" Mid Bass Neodymium Loudspeaker - 8 Ohm (Each) 

PRV Audio’s 8MB700FT-NDY 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 more precise mid bass. Superior fidelity is achieved through a perfect combination of a non-pressed cone with a smooth frequency response and a surround ring specially designed to allow high displacement without increasing the distortion.

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-NDY is an extremely efficient 8″ midbass, due to its wide frequency band and 98 dB sensitivity rating, this speaker is ideal for pairing with compression drivers, on 3-Way system (with a suggested 95 Hz, 12 dB/octave high pass filter in place)!

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.
