A limited space, small enclosure bass speaker module is shown, for providing an enhanced perception and sound level of bass frequencies. An acoustic transducer is mounted on an end of a closed elongated, cylindrical member of rigid construction. The cylinder provides acoustic loading of the transducer, and can be either an acoustic suspension or a bass reflex form; the bass reflex form has the bass reflex port located coplanar to the transducer. The resulting structure is a an oriented point source. The module is then acoustically coupled to its surroundings by being mounted so that the transducer face is in a corner. The result is to convert the surrounding environment into one element of a horn loaded speaker, producing an enhanced bass effect. |
