DESCRIPTION
The XLT51E is a versatile high-efficiency subwoofer
designed for installation with smaller XLTE full-range
loudspeaker systems for extended deep bass output in
smaller installations. The black-painted 13-ply Baltic
birch enclosure and black perforated steel grille present
an attractive package. The XLT51E subwoofer has an
integral 150 Hz high pass output filter that can be used
to directly feed XLT41E or XLT42E full range systems,
thus requiring only one amplifier channel to power both
systems. When used with a larger XLTE full-range
system, a separate amplifier channel is recommended
for each system. Five year limited warranty.
