Doesnt the extra power demand from the bass boost hurt the small drivers?
At first glance, your impression would be exactly right. However, when all the drivers are used in a long column, there is a 10 dB acoustic gain over much of the frequency range compared to a single driver, making the resulting efficiency of the column much higher. Only one tenth of the power is needed for the same listening level. In addition, there are 25 drivers, each of which will handle at least 10 watts. The entire column will handle 250 watts and still not exceed the single driver power handling. The heat dissipation capability at high power is outstanding with 25 voice coils per channel. A single coil used in one large woofer is not able to dissipate heat as effectively in comparison. Also, since the system will handle such high power over the entire frequency range, it means that the mid and high frequency peaks can be handled effortlessly, far better than a system having a single mid-range and tweeter.
