Bass Reflex Performance Envelope - Part 3: A Practical Example

In this article, Gary Gesellchen (Vanatoo) completes his Bass Reflex Performance Envelope exploration. After concluding the main analysis portion of the article determining his novel approach to estimating the performance envelope available from bass reflex loudspeakers, Part 3 shows an example to see how his calculations all work together, and addresses some practical considerations. This article was originally published in audioXpress, September 2023.

This Bass Reflex Performance Envelope article series describes a novel approach to estimating the performance envelope available from ported loudspeakers. Part 2 expands on the system analysis, showing how driver and port sizes determine how loud and how low a system will play, and how that relates to generally available drivers. This article was originally published in audioXpress, August 2023.

Targeting speaker designers/builders, Gary Gesellchen (Vanatoo) wrote a sequence of three articles discussing Bass Reflex Performance. Essentially, this series takes a novel approach to estimating the performance envelope available from ported loudspeakers, considering port and driver sizes and multiple applicable parameters, and comparison with the performance from a passive radiator. This article was originally published in audioXpress, July 2023.

As audioXpress August 2023 focus on Acoustics, read the report on Electroacoustic Enhancement and Active Acoustics. René Christensen details the model and application of the SonicEdge Ultrasound Speaker. Philipp Paul Klose writes about Noise Cancellation in Automotive Audio. And we visit the Western Electric Tube Factory in Rossville, GA. Read the AXPONA 2023 show report, how to Design a True Midrange Driver, and how to build an Instrumentation Amplifier-Based Preamplifier Line Stage.

audioXpress July 2023 provides an updated market and technology overview of Audio Amplifiers, includes the review of the Hypex Nilai500DIY 500W Power Amplifier Kits, a visit to Dutch company Grimm Audio, and an interview with Rémi Guastavino to discuss the new GRAS EQset measurement microphone series.
