[. . . ] Before fine tuning, double check that all the connections in the installation are correct and secure. Moving the speakers further from the walls will reduce the general level of bass. Space behind the speakers also helps to create an impression of depth. Conversely, moving the speakers closer to the walls will increase the level of bass. If you want to reduce the bass level without moving the speakers further from the wall, fit the foam bungs in the port tubes (figure 6). If the bass is uneven with frequency it is usually due to the excitation of resonance modes in the room. Even small changes in the position of the speakers or the listeners can have a profound effect on how these resonances affect the sound. If the central image is poor, try moving the speakers closer together or toeing them in so they point at or just in front of the listeners. If the sound is too harsh, increase the amount of soft furnishing in the room (for example use heavier curtains), or reduce it if the sound is dull and lifeless. Test for flutter echoes by clapping your hands and listening for rapid repetitions. Reduce them by the use of irregular shaped surfaces such as bookshelves and large pieces of furniture. Whenever possible fit the spike feet supplied after you have optimised the positioning. Initially, screw the lock nuts fully onto the spikes and screw the spikes fully into the threaded inserts in the base of the speaker. If the cabinet rocks, unscrew the appropriate spikes until the speaker stands firmly on the floor and lock them in place by tightening the lock nuts against the base.
