I turned down the power on the sealed so neither one of them would pass xmax until below 3 hz. As mentioned, it might be a bit more fair to add a bit more power to the sealed since it doesn't really need to go that low, but you still...

Quote:Originally Posted by LTD02 well, let's end this non-sense right here. the port air velocity in your design at 2hz is 72 m/s, which is 162 mph! that is a freak'n category 5 hurricane. lol. As stated in post 1, and about 60...

Quote:Originally Posted by N8DOGG So why the hell do you care if it works or not if you're not going to build it? You seem like a kid with ADD. Though I have to admit, I'm impressed with your trolling skills but it's all getting old...

This thread has no point anymore. I've provided proof with simulations and real world measured occurances. No one has effectively argued any of it despite pages of conjecture and speculation with no supporting evidence. Every link...

Why is everyone so scared to even mention the sneeze? It invalidates all of your collective arguments in one fell swoop. EDIT - posted too soon. SO you are saying the power of your lungs is several times more powerful than the Bl of...

Quote:Originally Posted by Stereodude Why don't you just build it and measure it already since you seem to have it all figured out? Why don't you? Probably for the same reason I can't. There simply is no affordable supporting...

Quote:Originally Posted by LTD02 noah, the spl advantage is about 2.5 times less than "a couple db". it is 0.1db at 20hz and increases to 0.8db at 10hz, assuming that the port is not chuffing (very large roundover required). if...

Quote:Originally Posted by imagic The problem is not whether things like air compressors exist and whether people 'believe' in the physics behind compressed air - it's the weakness of the forces at work. The large chamber will...

What's up guys? A real world example has you stumped as you try to figure out how to argue against 45 m/s velocity coming out your little tiny nose hole? (No doubt high compression situation but it does NOT revert to a sealed hole even...
