Title: Bass loudspeaker enclosure using opposed vertical deposition - has units mounted in top and bottom of cabinet and directing sound via floor and ceiling to reach listener's ears in phase
IPC: H04R1/22
Filed: 1988-02-12
Abstract: A symmetrical air-filled enclosured (4) carries bass loudspeaker units (1,2) in its flat top and bottom faces.  Airtight seals (6) are provided between the unit edges and the cabinet material. The assembly is mounted on legs (7) which maintain a separation from the floor (3) beneath of at least one-half of the loudspeaker's cone diameter. Sound can thus pass to a listener by reflection both from floor and ceiling. The sound heard by persons disposed horizontally with respect to the enclosure arrives from both sources in phase, and associated reflections from walls are also in phase. Respnse is as enhanced and parasitic resonances are self-cancelling, directivity being eliminated. ADVANTAGE - Opposed vertical disposition avoids disadvantages of other twin-unit loudspeaker arrangements, including out-of-phase losses, directivity, and reflection distortion, and does not involve use of bulky cabinets.
