Subwoofer Placement In Non-Rectangular Rooms

January 2, 2019 by Bohdan Raczynski

Subwoofer Placement In Non-Rectangular Rooms

This article examines the problem of subwoofer placement in odd-shaped rooms, exploring corner locations of subwoofers and some pros and cons of single-woofer versus dual-woofer systems for a given placement within a listening room. In the article, the author extends the analysis and actually generates the “room contribution” curves for a non-rectangular room. This article was originally published in audioXpress, September 2002.

R&D Stories: Curing the Open Office Noise Epidemic… With Nature?

R&D Stories: Curing the Open Office Noise Epidemic… With Nature?

Noise distraction is the number one complaint for open plan office workers according to a recent study from Oxford Economics. Robert Manassero provides a fascinating account of how, after experiencing its own challenges with noise in an open office, Plantronics tested and developed its own solution to noise and distraction using biophilic acoustics or acoustics based on elements from nature. This article was originally published in audioXpress, August 2018.

Fresh From the Bench: IK Multimedia ARC 2.5 Advanced Room Correction System

For the Test & Measurement Focus published in audioXpress March 2018, two of our authors tackled IK Multimedia’s ARC 2.5 room correction system. Ron Tipton investigated IK Multimedia’s claims that the new ARC 2.5 improves the audio monitoring accuracy of speakers in any studio or listening room, while Stuart Yaniger tested the new MEMS measurement microphone available with IK Multimedia’s ARC 2.5 System. In this section of the review, Ron Tipton looks in-depth at how to make the best use of the acoustic room correction possibilities of the ARC System.

Practical Applications for SPL Meters

Practical Applications for SPL Meters

Following his original 2008 essay on sound pressure level (SPL) meters, in this article for audioXpress published in March 2015, Ethan Winer considers some practical applications for a basic SPL meter, such as calibrating loudspeaker levels and measuring room acoustics, using a simple Galaxy Audio CM-130 SPL Meter as an example. He then moves on to a more sophisticated model, the NTi Audio XL2.
