Past Event: Creating A New Loudspeaker Design

February 26, 2020 at 7:30 pm

Location: Digipen Institute of Technology, Redmond, WA

Moderated by: Greg Dixon

Speaker(s): Gary Gesellchen | Vanatoo

 Loudspeaker designers and the music lovers who use their products share a similar dilemma. When confronted with a clean sheet, the designer must ask themselves "what's possible?" When shopping for a new set of speakers the music lover would like to know "what's reasonable". They would both like to know what to expect from a system just by looking at it.

While overall sound quality is what defines a system, the bass response is typically what dictates the size, power requirements, and a good deal of the cost of a loudspeaker system. Looking at the family of designs typically possible from a "bass reflex" loudspeaker allows the designer to quickly home in on the requirements for a proposed system. The results can also be used to assess what to expect from an existing design. Another question asked is which bass reflex designs can be realized with a ported cabinet versus the family of very attractive design options that are only realizable with a passive radiator design.

Join us on February 26th to learn more about the yin and yang of creating a commercially viable loudspeaker system.
