I still feel that a complementary upper bass channel is begging to be used in this system.

Yes, Romy, the upperbass channel is absolute mandatory. My comments were only about the particular driver, nothing more than that. The is no way he could get good upper bass with 8" driver, not to mention with a driver having so wide leather surround. He needs at least 12" driver with harder and faster suspension in order to get the fundamentals right. The best solution would be to use 2 upper bass channels, arranged symmetrically below and above his main channel. Unfortunatelly his setup does not allow such configuration...
There are a lot of aspects in this system which I don't like. In my view, the tweeter/midrange integration is absolutely compromised. First of all, the tweeter is very far away from the acoustic center of the widerange channel. This could be translated as strongly unfocused sound, because the tizzing of the supertweeter will be completely isolated by the main sound. Not to mention that the tweeter has very different sound signature within context of the speed of dynamic gradations, dispersion patterns and tone... But the most disturbing thing of all is that the tweeter is placed above the widerange channel. It is going to "pull" (psyhoacoustically) the sound at its axis, making it to sound very tiny, and considerably lowering the size of the acoustic instruments. It would be much more appropriate if the tweeter was placed below the midrange horn, allowing the sound to be integrated on the midrange axis in a way that tweeter completely disappears as a sound source as if it is non existent. It is extremely important for any acoustic system that the sound must be "pulled" by the midrange channel (not by the HF channel) and this is the only way to get really proper sound, but this is also the most difficult thing of all...
