I could not agree more! The cost of many full range speakers that go very low is quite prohibiting. There is an argument that the lower the frequency the bigger the cost of the driver and amplification. The higher the frequency it gets cheaper. There are also implications for accuracy too. Less are also needed as we are less sensitive the directions of lows. More tweeters means better directivity at frequencies that lose the most with inadequate coverage. It also means the drivers position is more accurate when computing a decoder. There are also other benefits, at the cross over frequency, due to the close proximity of bas/mid/top drivers, distortion occurs. Due to interference. Also higher frequency drivers take up less space so is easier to hide. A decoder that has control of all separate drivers in a space should therefore be more accurate.
