The VO-FR500s are ultra low inductance, high efficiency Full Range Voice Optimized drivers featuring a precision engineered dual cone design. The ultralight whizzer cone/cap is attached to the coil former to increase off axis response for greater output at higher frequencies augmenting the primary lower playing frequencies that the midrange cone is designed to disperse. The independently focused acoustics of each cone have been optimized for smooth and coherent frequency blend ensuring listeners experience a fantastically broad tonal spectrum from bass to treble with no audibly perceptible phase shift or delay. Complete your pro audio system today with these loud and clear full range speakers.
Made with motorcycles, boats and UTVs in mind, these speakers will overcome the harsh conditions and environmental noise you’ll encounter on road and off.
