thank you. i've noticed that when the frequency is split into separate ranges and fed into the associated driver the fact the driver only has to deal with a limited "range" or a more focussed range I should say (dictated by the crossover points) it helps a lot with transients. so essentially, what was expected of single dynamic drivers (exotic, expensive materials, essentially the lightest and stiffest materials that could be implemented) can now be spread out across generally less Exotic drivers that still have abilities and characteristics of their own.
and i'd agree with the dual dynamic driver mention, anything that takes load off one driver and gives to another can then basically free up the original driver to concentrate on what it does best, essentially more bass requires more air to move and bigger drivers can do that while smaller drivers can concentrate on higher freqs can be smaller in size so with only bass frequencies to worry about the larger diaphragm has nothing else to confuse or muddle up its job. resulting in theoretically a cleaner reproduction. (cheesy grin)
so basically BA is better than DD for IEMs?
