Why having two gains on a mono subwoofer is a good thing?

Often you hear the term “subwoofers are non-directional”; this is not true subwoofer placement is harder to pick when to low frequencies are crossed . The wider the room, the more directional the subwoofer. The easiest solution is to use two subwoofers in the front: one on the left and a second on the right. The signal to both is mono. In some applications, users might have small front speakers or planer speakers. Both speakers have an early roll off in the sub-harmonics. The planer needs help from 150Hz on down, having two front subwoofers placed on the left and the right is a health solution to this problem.

Two Subs

While having two subwoofers is better than one, the MONO signal that drives these subwoofer keeps them from projecting the three dimensional images in the sub- harmonics. The use of two subwoofers allows you to cross the sub up to 150 Hz sound quality, imaging and staging. The two-front-subwoofer-system is an excellent solution to planer speaker’s low frequency response early roll off. When locating these subwoofers in a close proximity to the stereo satellite, the subs will enhance low frequency extention. It will be better to have a stereo subwoofer to help in the lower bass notes and their placement.

If a bass Guitar player was standing on the left side of the stage, and he played an EE note (42Hz) then the right sub will also respond to that and create havoc on the stage. In fact if you only have one single sub in the room and it’s placed on the right side of the room, while the bass guitar player is playing his music on the left side of the stage. As soon as he hits the EE note the sub speaks out on the right and completely destroys the stage. To give you three- dimensional front-end bass that allows you to have a low frequency dynamic stage, Earthquake designed dual input circuits that use buffers to maintain your stereo separation on the processor side while mixing stereo front signals to produce 3D bass.
