I'm trying to understand exactly what makes a sub "tight" vs "boomy". 1) Driver size: I've heard some people say that smaller drivers are tighter and faster. But I've also heard some people debunk that statement, saying its more of a function of motor quality. Which is true? 2) Ported vs sealed. I've heard many people say that sealed subs are better than ported for music because the group delay is higher in a ported sub. But when I look at group delays for my Tempest (using LspCAD) the group delays are very similar to a sealed sub within the typical music bass range (>35Hz). Is ported only a disadvantage for music if the tuning is close to the range of music bass (like car subs tuned way up high, like 40Hz)? 3) Enclosure size. For some reason I was under the impression that a smaller box exhibited better damping on the driver because in a larger box the sub is more sensitive. But it seems like the low q subs have large boxes, while the small ones tend to be boomy. Whats wrong with my reasoning? I know this is a lot of questions for one thread, but I'm really trying to get a grasp on what makes a sub sound good.
