The middle speaker is a real loudspeaker. The top and bottom cones are passive radiators. In the same way as a ported loudspeaker, a passive radiator system uses the sound pressure otherwise trapped in the enclosure to excite a resonance that makes it easier for the speaker system to create the deepest pitches (e.g., basslines). The passive ...

The Firebee's main air launch platform is the Lockheed DC-130 drone controller aircraft, which can carry four drones on underwing pylons. The Firebee is typically snatched out of the air by a recovery aircraft that sweeps up the drone's parachute, simplifying recovery and reducing damage to the target from ground impact.
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.
The General Atomics MQ-9 Reaper (sometimes called Predator B) is an unmanned aerial vehicle (UAV, one component of an unmanned aircraft system (UAS)) capable of remotely controlled or autonomous flight operations, developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF).
