Message: <blockquote data-quote="Buck" data-source="post: 8774522" data-attributes="member: 591582">If you study how aero engineers design jets that go over the speed of sound, you can apply some of that knowledge to cross sectional area and how that affects the density of air when it hits solid surfaces.  I apply some of my “flow of air” knowledge and structural geometry to eliminate high pressure resonance weakness on parts of the box shells from studying things like air flow during the transition of jets between right below the speed of sound into mach+ speed.  You can visually learn how how density affects airspeeds and what problems that can possibly cause, and then you can see ways to make boxes stronger and flow better both internally and on the outside.[ATTACH=full]34454[/ATTACH][ATTACH=full]34455[/ATTACH][ATTACH=full]34456[/ATTACH][ATTACH=full]34457[/ATTACH][ATTACH=full]34458[/ATTACH][ATTACH=full]34459[/ATTACH][ATTACH=full]34460[/ATTACH]Aircraft airflow is more DC like the AC like, if you will, but how air pressurizes is still all very similar.  Planes can develop different resonance problems depending on what speed they’re going, because different parts of the planes vibrate differently at different speeds.  Planes can vibrate themselves apart from resonance problems and lack of resonance-proof bracing.[ATTACH=full]34461[/ATTACH][ATTACH=full]34462[/ATTACH][ATTACH=full]34463[/ATTACH]You can see how resonances can break an aircraft apart, and since we’re doing loud bass, we are literally creating massive pressures, and that massive resonance-inducing energy has to be tamed, or else everything will fall apart.  That’s why we use wood for speaker enclosures; wood resonates less, because it has more random clumps of molecules than some things like forged metals do.</blockquote>
