Quote:Originally Posted by imagic Long tubes create problems with resonance and with friction that are less prevalent in shorter tubes. That's the crux of this discussion. There are very real limitations withlong tubes when it comes...

Quote:build box, test at high level, plug port, test again, compare results. You should visibly be able to see the excursion difference or hear any port noise. Am I missing something here?What does that prove if you don't map out the...

Quote:Originally Posted by notnyt Welcome to the internet, and the AV SCIENCE forum. Go ahead and use the scientific method and test it. I can't afford to buy supporting equipment to set it up and test it as I've said several...

Quote:Originally Posted by imagic What will actually happen is higher notes will start bouncing around inside that tube and the resonances will build up and you'll hear the bass come out with that 'piped-in' sound because that's...

Quote:Originally Posted by tuxedocivic I'd test it. But I honestly don't know where I'd put the pipe. Or where I'd cut a hole in my box... I'd sure be greatful if you did. But where to put the port is the least of your worries. ...

Quote:Originally Posted by noah katz Actually diy is correct for the current point of discussion; the port velocity is high because of resonance, but the discussion is about the implications of the velocity, not what causes it. Not...

Quote:Originally Posted by Scott Simonian Well, we have ALL been saying that your simulation is inaccurate and will not work. So what has all these last few pages been about if you have picked that up? And btw, this is the Do It...

Quote:Originally Posted by Scott Simonian Wait! WTF!?!?!? All this BS back and forth with all of us and you aren't going to even build the damn thing? *sigh* Did you read post 1? I never said I was going to build it, I wanted to...

I agree with that completely but hopefully with a bit more scientific rigor than Mythbusters.

Quote:Originally Posted by imagic FWIW ...Well, I surely do not want to expand the topic, I'm trying to narrow it or end this completely but I'd be happy to discuss this by email or PM if you like. Post 137 shows my opinion on the...
