Product Description

The LL916C is an economical yet powerful piezoelectric underwater speaker developed, patented, and manufactured by Lubell Labs of Columbus Ohio. The LL916C continues to set the world record for having the widest frequency response and output level of any commercial underwater speaker made, at a price that is reasonable and affordable. Because of its rugged PVC construction, the LL916C is nearly immune to damage, and may be used in test tanks, swimming pools, rivers, lakes, and oceans. The LL916C is provided with choiceof audio isolation transformer box with cord (see below), allowing phone jack connection to popular commercial sound amplifiers of various power & impedance ratings.
