[QUOTE="Norval, post: 1016106, member: 62"] I stand by what I said in that fast, at least from a technical point of view, refers to impulse response, or shall I say it should. That being said [member=20216]LouisF[/member], I tend to agree with the statement above as well, and that could be opening a can of worms. I think the concept is mostly misunderstood, and peoples description of a fast speaker usually only relates to bass, but a "fast" driver should actually be more prominent in the midrange. As someone that likes to build speakers myself I tend to lean towards midrange drivers with lower Qts to sound better in the mids, but maybe that is just placebo. Could the description of fast be the effect of group delay? To some extent it is probably right, but can we really hear it? Or shall I ask, how much delay at 35Hz before it really become audible? People often describe sealed boxes as fast, and ported as not fast. But the driver impulse response of a driver mounted in a ported box should be faster than that of an sealed box. The port itself has a longer group delay though. I also sometimes wonder if the terms fast in reviews are related to lack of bass extension, and maybe sometimes a peak between 50 and 100 Hz to give one that kick in the chest feeling? :thinking: Honestly I think that is very often the case.
