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.

Simulation Techniques: Double Bass Arrays

Although the sound field in a room at low frequencies is one of the most discussed topics, approaches to dealing with room modes are typically treated as an optimization problem, and not correctly defined. This article explores a different strategy: the so-called Double Bass Array layout, using several subwoofers placed in a pattern, on the front and rear walls. Using advanced simulation techniques in order to understand what truly happens in the resulting room mode behavior, sound pressure levels, and resonances, this article builds upon existing research (Geddes, Welti, Devantier, et al.)

Brane Audio RAD Speaker Technology Named in TIME’s Best Inventions of 2024

As TIME revealed its annual list of the Best Inventions, which features 200 product, technologies and innovations changing our lives, there was a surprising mention of Brane Audio's Brane X portable speaker as a winner in the Entertainment & Gaming category. As audioXpress and Voice Coil readers learned earlier - and coincidently James Croft writes about in Voice Coil November 2024 - the company's Repel-Attract-Driver (RAD) that is part of the Brane X design, is indeed the first effective embodiment of a negative-spring woofer that bends Hofmann’s Iron Law.

Celestion Introduces CF1230BMB Extended Excursion Compact Bass/Midbass Pro Audio Woofer

Celestion introduced the CF1230BMB 12-inch woofer, suited to both bass and midbass professional audio applications. The new ferrite magnet, cast aluminum chassis driver is engineered for a longer throw than conventional midbass speakers, being able to produce more low-end when loaded into conventional two-way enclosures. Celestion also says the new compact woofer excels as a bass unit in compact subwoofer applications.

Mackie Redefines What’s Possible with Next-Generation of Affordable CR Monitors

Mackie announced the third generation of its Creative Reference (CR) monitors, now adding a flexible tone control and location switch for even more flexibility in any application. The new powered studio monitors now can switch between desktop and bookshelf speaker modes, and shape the sound for more bass or added high-end sparkle with the tone control knob, depending if the monitors are being used in the studio, for casual listening, partying, or entertainment. The updated Mackie CR Series includes models with 3.5-, 4.5-, 5, and 8-inch woofers, with and without Bluetooth, plus an 8” subwoofer.
