Abstract
An acoustical equalization device is designed to be attached to the front of a stereo speaker and includes a plurality of moveable baffles which may be used to either reflect or absorb sound waves being emitted from the speaker. The baffles can be slidably positioned along a plurality of rods forming a part of the device and may be pivoted into a desired sound adjusting position. Modified baffles include through-extending apertures into which sound modifying cones may be removably positioned, while the cones may be provided with pivotal closures to further affect sound quality. The device is used as an aid in equalizing a sound system so as to obtain the best audio response curve without the use of electronic equalization systems.
