Listening Room & Subwoofer Position:

Positioning Examples

Subwoofer positioning is integral to the successful application of any surround sound system. It is very important to keep in mind that the proximity of the subwoofer to a wall or a corner contributes to an increase in efficiency (SPL) because of the "mirror effect" also referred to as "corner loading".

It is therefore advisable that you place the SUB-80X near a wall, or preferable in the corner of the room. That will increase the subwoofer effect by 2 to 3 decibels, without raising the volume control of the SUB-80X.

Fine Tuning:

The fine tuning process includes creating a smooth transition of music between the subwoofer and the next speaker up: usually a woofer or a mid-range. As shown in the graph below; a smooth transition between lower and upper bass is directly relative to the crossover setting and the capability of the next woofer up to reproduce lower frequencies. Keep in mind that vocals extend down to 70Hz, adjust your SUB-80X accordingly.
