Dolby Atmos: Dispersion Requirements for Ceiling Speakers

In this blog article we look at the dispersion requirements for ceiling speakers in a Dolby Atmos system. We consider the example of a system with 4 ceiling speakers and two seating rows and show how dispersion requirements change for: Speakers firing straight down vs. angled at the listening area. Different ceiling heights (9’6″, 8’6″ and 7’6″). […]

Speaker off axis: constant beamwidth 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 beamwidth 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 off […]

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 / […]
