In the last years IEM manufacturers crammed ever more ba drivers in their in ears. The latest craze I found is the U 18T that incorporates "8 low drivers and 8 mid drivers with the high and high-mid drivers", 18(!) drivers in total.
I understand that to a certain degree it can be usefull to split the frequency response into three or maybe even four ranges and give it a specialized drive for this range. Of course it gives the problem of the overlap and the difficulty to design a proper crossover to achieve a smooth level over all and no phase errors.
But why this massive amount of parallel drives for a given frequency range? I know that big living room loudspeakers and especially loutspeakers for bigger audiences very often have multiple drives, but sound pressure is obviously not that big problem with in ears. Why is it worth to undergo all that problems to squeeze those ba drives into a tiny shell? Except of course as a big selling point, as for most people more of a good thing equals a better product (faster CPU in a smartphone, more horsepower in a car for instance).
