[QUOTE="Cleansound, post: 23545"] As I said, it's a similiar "principle". The idea is to break down the frequency to some extent and therefore also the inclusion of the mouth port. Studies have shown that many loudspeakers are in effect a Helmholtz in reverse. The Helmholtz method has been applied in certain areas not to act purely as tuned absorber, but has been applied many times to work as I said in reverse. Guitars and violins work on a similiar principal, but in reverse, thus not trapping the sound. From what I have read so far, and I am NOT an expert on the topic, the Helmholtz principal is being used nowadays in many varying methods, shapes and sizes. http://www.phys.unsw.edu.au/jw/Helmholtz.html http://en.wikibooks.org/wiki/Acoustics/Flow-induced_oscillations_of_a_Helmholtz_resonator I could be wrong but it was after a few mails to M/L back and forth that I started reading more into this. Norval here is a nice one for you I know you will enjoy http://www.far-audio.com/acoustic_panels.php [/QUOTE]
