Recently while auditioning speakers for my setup I came across a common dilemma.... do I really need the bigger speaker? i.e. CSi3 vs. CSi5... FXi3 vs. FXi5... RTi8 vs 10 or 12... etc. You get the picture.
While listening to all of these most of the time these speakers all have no problem hitting the 80Hz that theyre usually crossed over to the sub at, and have identical upper limits freq. resp.-wise. But there just seems to be SOMETHING that always made them different even though they technically are reproducing the exact same range and are from the same series and voice matched an all that... So I came up with three options
1) Is there just something about the timbre of the larger driver that makes for a better (or just different) sound quality. Guitar players may understand the analogy that you can play a note on a string, but if you go up or down a string you can play the exact same note technically, but there will be an ever so slight difference if you play the two back to back.
2) The crossover frequency of the speaker from the driver to the tweeter is different resulting in a different sound.
3) I am just nuts and there is no difference.
Is it a little bit of all of the above, or something Im not thinking about? Im interested if this is obvious to other people and your opinions on the cause. Thanx
