Efficiency can be improved, but at the detriment of other aspects of the performance. I think if producing high quality, efficient designs was that easy, we'd see a lot more on the market. If I remember rightly, you can't have high efficiency and deep bass from a small cabinet with an easy impedance load (not from traditional two way speakers anyway). It's either a balancing act or a compromise on one or more of those aspects. I may be wrong, but I'm sure that was quoted to me by one speaker manufacturer.
