SPECIFICATIONS JF50S
DESCRIPTION
A 2-way full range system (passive LF/HF crossover) in a
compact asymetrical left and right trapezoidal enclosure.
Includes 2x 5.25-in woofers and a 1-in soft dome tweeter.
Impedance is switchable: 4 Ohms or 16 Ohms.
APPLICATIONS
The JF50S is engineered for exceptional performance in the
nearfield from a compact enclosure. Left and right side driv-
ers are magnetically shielded for use on either side of video
monitors. Very effective as a fill/delay element in larger over-
all systems or for foreground/background music reproduc-
tion. Six year warranty.
Applications include:
MultiMedia
Small Retail Spaces
Presentation Suite
Small HOW’s
Theaters
