The LT-PMS (Long Throw-Planar Magnetic Speaker) Series from HPV Technologies is a collection of speakers designed specifically for long throw, speech transmission. The clarity and size of the LT-PMS series using the MAD-1 planar driver makes them a powerful tool, especially in situations where clear and articulate verbal instructions or commands must be understood. LT-PMS systems are currently in use by law enforcement on bicycles and patrol cars, for crowd control, and in SWAT mobile command centers.
