Siltech speaker simulation Project background Siltech specializes in very high quality speakers, based on ‘Silver Technology’. When you listen to music played through these speakers, you immediately recognize the quality and class of these systems. Siltech continuously works on improvements and thus remains at the top of this segment. Physixfactor has carried out an analysis for Siltech into the influence of the positioning of some panels in the loudspeaker and their resonance.
Determine the effects of acoustic absorption and resonance within a new loudspeaker and the influence of the orientation of angled internal panels. To what extent do the panels participate in the resonance, and how can this influence on the frequency spectrum be made clear? What dimensions should the panels have to meet Siltech’s desired quality standards? The use of damping material in the speaker affects the characteristics of the system. Analyze with Finite Element Method (FEM) the locations where the damping material has the greatest effects on the sound.
Siltech can now handle the panels and damping material independently. The quality has improved. The same in good foreign articles by experts:
“A computer program called Comsol, also used by NASA in the space industry, was used to address the influence. The result was a speaker capable of reproducing up to 118 dB shaped, extremely dynamic and fast – and very musical.” D en D audio
“It did indeed seem less than usually affected by room modes, as Siltech claims, and it played bass melodies with a clarity and alacrity that eludes most other speakers.” Hifi News
“There was never a hint of the cabinet ‘bloom’ that most box speakers display somewhere in the lower midrange as a result of internal air resonances and/or structural resonances within the enclosure. This means that the Pantheons create a stereo image that really does appear to hang in space independent of the speakers themselves.” Hifi News
“What makes COMSOL so special? After all, CAD/CAM technology isn’t actually new and Finite Element Analysis (FEA) is fast becoming just another item in the designer’s toolbox, a shortcut in the prototyping process. But where FEA allows designers to model the mechanical form and behavior of parts without actually making them, COMSOL goes a stage further, allowing analysis of fluid and gas dynamics.” The Audiobeat
“What’s not so obvious is that COMSOL has enabled the company to look at the behavior of both the cabinet and the air pressure inside it simultaneously, using the dimensions, shape and venting of the enclosure to dissipate structural and air-mass resonance, virtually eliminating the need for damping materials to deal with either problem. In fact, the internal damping element has been reduced to a single, dome-like pincushion placed in the base to handle the vertical mode between the only two parallel surfaces in the whole structure.” The Audiobeat
