You might be wondering why the foam is used and why it sets our Home Theater audio solutions apart from the competition. The most noticeable feature is the unusual use of foam on the front of each unit. Most people who are in to performance audio have probably heard the terms before, but if you don’t really understand what they are or how they affect a speaker, this article is for you. The value of Rparallel should be increased until the bass seems to be balanced with the rest of the SPL spectrum. Baffle step and diffraction are two very important concepts to understand in speaker design. The Vertex series takes a ground-breaking approach to design. Adjust the value of Rbsc a) If the bass is still too weak, then the amount of attenuation is too little. Layout of the loudspeaker and measurement point locations. The design brief was to produce a range of high performance, high SPL, high sensitivity loudspeakers, whilst maintaining a shallow cabinet depth capable of in-wall installation. Sound Diffraction Over Noise Barriers with Added Devices Installed on the Top Edge. How Does The Vertex Series Solve Edge Diffraction? However, a minimal cabinet depth, as exhibited by the Vertex Series of loudspeakers, prohibits this traditional way of combating edge diffraction. To avoid this, the front edges of the speaker can be rounded – This is quite common in speaker design. The result is a colouration or “blurring” of the sound. These interfere with the loudspeaker’s initial wave. Cabinet edge diffraction is a phenomenon where secondary sound sources are created by acoustic diffraction on the edges of the cabinet at certain frequencies. The theory of Geometric Optical Diffraction has been used to investigate the effects of sound diffraction at the edge of a loudspeaker cabinet (Bews and Hawksford, JAES).
