L-Acoustics MTD108a Loudspeaker

The MTD108a is a passive 2-way loudspeaker enclosure containing a 1" exit compression driver that is loaded by the 8" loudspeaker in a coaxial configuration. Advantages of the coaxial approach include: single point source radiation and excellent phase response, total wavefront coherency at all frequencies and axi-symmetrical directivity that produces identical horizontal and vertical coverage. Coaxial design also provides LF/HF superimposed dispersion characteristics that are free of polar lobing effects typical of traditional horn and woofer combinations. The end result is natural, studio monitor level sound quality, ideal for proximity use and perfectly matching semi-reverberant environments.
