Our rooms pose a huge obstacle to achieving accurate low and low-mid frequency response. When a room is excited by a sound source such as the loudspeaker’s, room`s resonances occur, and they create destructive interference which cancels out a significant part of the sound source radiated information. This problem can be treated by improving the room acoustics, by finding the best loudspeaker position or by having a loudspeaker with controlled radiation to minimize problems caused by the room’s acoustical properties.
