A moderate power, broadband projector has potential applications in deep-towed seismic profiling and underwater acoustics research. Vent holes are introduced into the pipe walls to increase the projector response between the first two resonances at 2300 and 4350 Hz. The finite-element modeling of the projector is described and theoretical and experimental results are compared. The projector has useful acoustic output over a two-octave band with electroacoustic efficiencies ranging between 20% and 72% over most of the band. The projector has no maximum-depth limitation, but cavitation may limit its performance at shallow depths.
