Where do we begin? This presentation called, “Fun with Subs”, was one of the discussion topics at our last F.L.A.T. meeting. What is F.L.A.T. you ask? The Fraternity of Live Audio Technicians. We are a group of seasoned audio guys that are putting our heads together and telling physics to take a hike. We come from several places in the audio field and are sharing our experiences with one another to form a brain trust. This presentation will go over 3 ways to set up sub bass. You will also see several hybrid variation of the three. The idea here is to give you a good understanding of the 3 styles and hopefully help you to figure out which one will work best for each situation that you are in.

The primary three set up we are going to look at are Broadside, Gradient, and End Fire. I won’t get too much into the math because the presentation will cover that. The idea is to learn not only how to deploy these setups but also to learn which one is going to work best for you. Bear in mind that the “best” one may be a combination of setups.!

There are several variables to consider when choosing the right setup for you. Be aware of things reflective boundaries, the shape of the seating area, and how much low end the artist likes on stage. We can create very elaborate setups that can cut well over 20db of low end on the stage but this isn’t always a good thing. You may have an artist that like to have that feeling of low end on the stage and feels out of place without it.

In the presentation you will see a variety of setups, take one that looks like it may work for you and try it. The best way to figure out which ones will and will not work for you is to try them. See which ones give you the most success in the venues you work in. and remember that the setups that we have here are not the only ones out there. You may find that a combination of setups may work even better. You may even be able to take this new knowledge and create an entirely new setup that works for you.

Don’t be discouraged if it doesn’t work out the first time. We have plenty of setups that started out as being only “ok”. And after massaging them here and there we have turned them into very viable setups that work. So let’s go have some Fun with Subs!
