 FG (full outdoors) versions have no enclosure vents, somewhat reducing their low frequency response
A range of acoustically and aesthetically matched front-loaded low-frequency systems are available to compliment 
your full-range systems. Cabinet heights are the same as those of EVF and EVH full-range loudspeakers systems, so 
you can create functional, attractive clusters using these low-frequency boxes with almost any combination of EVF 
and EVH loudspeakers.
