BASS SYSTEMS

One of the limiting factors of conventional, passive bass drivers is the very large box size necessary for realistic LF performance. An excellent alternative is the use of a powered bass or sub-woofer unit. Whilst these are common for home theatre, they are less common for music use. However a correctly designed unit, carefully matched to the main system, can release an extra dimension of realism to music performances.

MJ Acoustics is a leader in this field and their MJ Pro50 unit is a sub-bass system ideal for use with our JXR6 HD and JX92S systems.
