Transitional Bass Reflex Alignments
The fifth article by Claus Futtrup in his series about loudspeaker bass reflex alignments explores the concept of transitional alignments, which is helpful in bridging between filter types. The example details a transitional alignment between Butterworth B4 and Linkwitz-Riley LR4. This article series started in May 2024 with “Computation of Bass Reflex Alignments," the series expanded with classical alignments such as the B4, the LR4, the IB4, and most recently, the CD4 vented alignment, in the August 2024 issue.
Speaker Builder: Open-Baffle Subwoofer Simulation with Akabak
Confronted with the impossibility to conduct reliable measurements in the low-frequency domain for his DIY speaker project, George Ntanavaras explores the alternative of relying solely on simulation software. To validate the design of an open-baffle subwoofer using the AKABAK software, created by German company R&D Team, he also explores the transition from measurements to simulation. His experiments contrast the near-field response measurements of his loudspeaker with the accuracy of the simulation using AKABAK.
