   en.wikipedia.org/wiki/Electrostatic_loudspeaker

   Electrostatics can also be executed as full-range designs, lacking the usual crossover filters and enclosures that could color or distort the sound. Since many electrostatic speakers are tall and thin designs without an enclosure, they act as a vertical dipole line source. This makes for rather different acoustic behavior in rooms compared to ...

6. Passive radiator (speaker) - Wikipedia

   en.wikipedia.org/wiki/Passive_radiator_(speaker)

   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 ...

7. Isobaric loudspeaker - Wikipedia

   Isobaric loudspeaker in a cone-to-magnet (in-phase) arrangement. The image above shows a sealed enclosure; vented enclosures may also use the isobaric scheme. Two identical loudspeakers are coupled to work together as one unit: they are mounted one behind the other in a casing to define a sealed chamber of air in between them. The volume of ...
