This is a transcription of my 40-minute presentation on low frequency control during the 59th AES conference on sound reinforcement in Montreal. Needless to say that 40 minutes is barely enough time to scratch the surface on such an involved topic. I therefore decided to focus on establishing the need for low frequency control, something I felt I could do within 40 minutes, and not attempt to cover each intricacy of the various solutions at our disposal.

I start by briefly refreshing on summation to make sure everybody is on the same page. Next we’ll meet the player commonly referred to as a subwoofer. We’ll continue with establishing the need for low frequency control, the essence of this introduction and finally have a look at current typical solutions.

I would very much like to thank Arthur Skudra for reviewing and editing this transcription.
