Speaker Lens for Onkyo SKS-HT588 hight speaker

The goal of this custom lens design is to maximize the directionality of audio coming from height speakers within a Dolby Atmos system. In order to achieve a more immersive listening experience, it's crucial to minimize sound emission at the speaker position and redirect sound upwards towards the ceiling, where the Dolby Atmos effect takes center stage. Instead of adding overhead speakers to the ceiling, this DIY solution uses an adjustable lens mounted on top of the height speakers to reorient the sound waves and direct them upwards. As I've found through experimentation, setting the focal point at 8mm above the speaker's surround membrane seems to optimize its performance with my current setup. While I'm not an acoustics expert by trade, the underlying principles behind how soundwaves emanate from a speaker have become increasingly clear as I explored various configurations and eventually landed on this lens design. To further solidify my understanding of loudspeaker directivity, I discovered an informative article published by Holosonics that succinctly explains how frequency radiates from a driver and illustrates the need for substantial physical modifications to optimize low-frequency directionality. One major advantage of using this custom lens is its ability to blend seamlessly with existing decorative elements without sacrificing any visual appeal. Additionally, despite experiencing slight difficulty when it comes to low frequencies, the design demonstrates promising capabilities in handling high-frequency audio with relatively minimal distortion. For individuals interested in designing an aesthetically pleasing yet highly effective Dolby Atmos system, I encourage them to examine my experiment closely and explore new possibilities that incorporate this approach. Perhaps with further tweaks and experimentation, users will find success in producing well-designed and esthetically pleasing systems capable of creating authentic immersion for viewers.
