Some producers have combined both auditory and visual subs together. I wonder how much more effective it would be for subclub to design both and audio and visual subs?
Those that say that visual subs are ineffective might be falling into the same trap as those who say that subs don’t work. They may be designing them all wrong. Hence they don’t work.
It might be a matter of learning how to design an effective visual sub, and somehow synchronizing it with an audio sub.
