Although I am not sure Sean meant to suggest that the straw trick for reducing port turbulence or "chuffing" is pure snake oil, I quite agree with him that you need to do some reading. There is much more to this question than you will conceivably get here, and you need a balanced view of your own.
That said, I am just as willing as anyone else to display my ignorance in public.
Any speaker design can result in a pleasing sound or not, depending on how it is implemented. Every design is built around tradeoffs--you win on the roundabouts and you lose on the swings, as the British say. Sealed enclosures have a relatively low resonant 'Q' but the actual resonant frequency will be higher than that of an equal-sized, properly ported box. Sealed box designs need more amplifier power, on the whole, because the cones have to work against the very stiff spring of the air trapped inside the box.
Knew that ? Great stuff. There's more. My supposedly humble opinion is that until you appreciate the tradeoffs involved in any audio design, you don't really appreciate the design.
