ISE 2025 First and Lasting Impressions
Integrated Systems Europe (ISE) 2025 celebrated another milestone in the event’s history, with the highest number of exhibitors and a 15.5% increase in visitors from the previous year. The show was mostly about solutions, signal connectivity, networking, and control technologies. Fewer opportunities for product launches, and an attendance increasingly dominated by end users.
SEAS Launches Toy DIY Kit With Metamodal TPCD Coaxial Driver
SEAS launched a new DIY kit to highlight the qualities of its state-of-the-art Metamodal TPCD coaxial drivers, allowing everyone to build a working speaker for evaluation and enjoyment. An evolution of the popular SEAS Joy kit that the speaker manufacturer already offered with a single coaxial driver, the new Toy DIY speaker is an enjoyable design that truly highlights the benefits of state-of-the-art Metamodal TPCD technology.
Test Bench: The New 7.5” MT19CP-8 Coincident Coaxial Driver from the SB Acoustics Satori Line
The new 7.5" coaxial driver from SB Acoustics' prestigious Satori line is built on a rather stylish aluminum-cast frame, totally open below the spider, with a cone featuring SB's proprietary Egyptian Papyrus material with a three-roll coated cloth-type surround, driven with a 1.52" diameter voice coil and neodymium magnet. The 1" tweeter is comprised of a coated cloth-type dome diaphragm, powered by a neodymium motor, which incorporates a resonant back chamber design.
Fresh From the Bench: RME Audio DPS-2 Power Supply and LNI-2 DC Filter and Stabilizer
When RME Audio released the DPS-2 Power Supply and LNI-2 DC Filter and Stabilizer, it left many of its faithful customers intrigued. The two new solutions are designed to improve the performance of its ADI-2 series of converters in critical applications. One is a super low noise linear audio power supply with a unique µfilter and sensor technology, and the other is an active DC filter with galvanic isolation. Stuart Yaniger explains how these two new solutions improve what is already outstanding.
Non-Linear Amplitude Modulation of Loudspeakers
Even a perfectly linear loudspeaker produces two types of distortions because of the movement of its membrane. First Doppler distortions, a.k.a. Phase Modulation (which the author addressed in his October 2024 article for audioXpress), and secondly distortions stemming from the Nonlinear Amplitude Modulation, characterized in this article. More importantly, this article also addresses how these harmonic and intermodulation spectral line distortions can be minimized and eliminated in loudspeakers.
