Abstract
An MTM loudspeaker in which an array of smaller drivers replaces each of the larger drivers in a traditional MTM design. Doing so reduces the total moving mass of the drivers reproducing the lower-frequency sounds in the MTM design, while still allowing enough air to be moved for the loudspeaker to reproduce sounds in lower frequency ranges that would normally be produced by the larger drivers and could not be adequately produced by a single instance of the smaller driver. For example, a single tweeter or supertweeter, or a pair of tweeters or supertweeters still serves a traditional tweeter or tweeter function in the MTM design (handling high frequencies), but a plurality of tweeters or supertweeters arranged in two arrays placed on either side of the tweeter(s) or supertweeter(s) handling high frequencies is tasked with reproducing lower frequencies not traditionally handled in loudspeakers by tweeters or supertweeters.
