I've been watching Hexibase again recently. Very cool designs with varying orders/degrees of acoustic suspension and t-lines. I see things like fluid-dynamics, mechanical inductance/impedance, and wave guides, and while I know a little about each, I still think I'm missing a lot here, enough that I don't even know the right questions to ask. Where would be a good place to start learning how to design things like this? Also, apparently hornresp is the predominant tool to use when designing one. Is this just because its free or does it do something better than software like matlab?
