Room Modes 101

What are room modes and how do they impact sound quality? Some unavoidable facts: ALL rooms have naturally occurring resonance frequencies called room modes or standing waves. If you read around the web you’ll find some more esoteric terms like eigentones or eigenmodes. I quite like calling them modal resonances. Room modes are the main cause [...]

How to Buy the Right Acoustic Panels: Part 1

How do you buy the right acoustic panels? This blog article is part of a mini-series that should give you a good overview on how to buy the right acoustic panels for your home theater, home recording studio or listening room. I say partially because acoustics is a very complex topic, and as you read [...]

Speaker off axis: constant bandwidth transducers (CBTs)

This blog article is the seventh in a series on speaker directivity and off axis response. This article will consider the off axis response of constant bandwidth transducers (CBTs) and consequences for acoustic design. Previous articles in the series established the theoretical foundation in terms of the psychoacoustic as well as subjective importance of speaker [...]

Speaker off axis: omnidirectional speakers

This blog article is the sixth in a series on speaker directivity and off axis response. This article will consider the off axis response of omidirectional speakers (“omnis”) and consequences for acoustic design. Previous articles in the series established the theoretical foundation in terms of the psychoacoustic as well as subjective importance of speaker off [...]

Speaker off axis: coaxial speakers

This blog article is the fifth in a series on speaker directivity and off axis response. This article will consider the off axis response of coaxial speakers and consequences for acoustic design. Previous articles in the series established the psychoacoustic as well as subjective importance of speaker off axis response, different ways to measure speaker [...]

Speaker off axis: constant directivity horn waveguide speakers

This blog article is the fourth in a series on speaker directivity and off axis response. This article will consider the off axis response of constant directivity speakers and consequences for acoustic design. Previous articles in the series established the psychoacoustic as well as subjective importance of speaker off axis response, different ways to measure [...]

Speaker off axis response: forward firing cone / dome speakers

This blog article is the third in a series on speaker directivity and off axis response. Previous articles in the series established the psychoacoustic as well as subjective importance of speaker off axis response and looked at different ways to measure speaker directivity.  Today we will look at the directivity characteristics of forward firing cone / [...]
