IK Multimedia Unveils New Extended Range of iLoud Precision Studio Monitors

IK Multimedia announced the global launch of its iLoud Precision series, another breakthrough in nearfield monitoring from the Italian company that revolutionized compact monitors with its iLoud Micro Monitor and iLoud MTM designs. The new range represent a completely new level in nearfield studio monitors for the brand, with three models that combine class-defying audio performance with the company's expertise in advanced digital signal processing and acoustic calibration.

Swedish digital audio processing pioneer Dirac and ASUS, the electronics powerhouse, have raised the bar on mobile audio with the new ASUS ROG Phone 5, which features a new level of sound fidelity for a smartphone with dual speakers, delivering a spatial soundscape and accurate stereo sound localization. The ASUS ROG Phone 5 now becomes the first smartphone to feature Dirac’s breakthrough MIMO mixed phase speaker co-optimization technology.

JBL Professional introduced FIR (Finite Impulse Response) Tunings for its AE (Application Engineered) Series, providing further enhanced performance for the premium installation loudspeaker line. 70 individual AE Series FIR filter files ensure support for a wide range of configurations and applications, optimizing frequency response and phase response to a finer degree of precision than traditionally possible with standard IIR “parameter-based” filters.

This article describes a DSP (Digital Signal Processing) technique developed to correct loudspeakers’ frequency domain and time domain distortions. Performance improvements, observed using square wave excitation, are documented here in time domain and frequency domain. This article was originally published in audioXpress, June 2010.

The question of phase response often arises when measuring loudspeaker systems. In this article, the author reviews setting the receive delay within a measurement system so that the displayed phase response is the “correct” one. This article was originally published in Voice Coil July 2011.
