+1, very logical.
Yet lower-moderate sensitivity speakers dominate the marketplace. These speaker manufacturers know that with the proliferation of affordable transistor wattage/power, an amplifier is readily available for the typical 85-87 db sensitivity 4 ohm impedance speaker. It seems the path of less resistance. Thus the default choice. 200-300 tube watts gets expensive relatively speaking.
I get the sense that good quality high sensitivity and easy to drive speakers may be more involved/complex and harder to get right. However when executed properly they can be quite the special product.
