Tweekerman, I am sorry if I ignored your post on the other thread, no disrespect meant. I have read about the Ravens and others you mentioned, but have not personally heard them. The Ravens may be the future, or the German Physic wave bending transducer, or the plasma tweeter(no full range yet, that I know of), or the Morel driver(discontinued), or the Sound Labs type of E-stat panels, or even a new generation Lowther type single driver which almost does it all, except for a small upper midrange peak and a bit bass shy. I would state that my prefence is some kind of full range single driver(cone,panel,ribbon,plasma,whatever) that really handles the entire audio spectrum, and does so in a point source fashion, presents a stable load, has minimal inherent phase shift and breakup modes, is very fast and efficient,and has no intervening circuitry between amp and speaker. And, of course, it has to play music. A friend once said to me,"I can eliminate all forms of audible distortion. Just turn the system off!" So it must be musical, technology is just a means to an end. There is alot of room for improvement in speaker systems and it will be interesting to see what may come in the future. Regarding your other point about building your own speaker system and saving money, I think it is a great idea and it can be done. I have done so and am very happy with my results. Remember, it is a learning process and very unlikely that your first one will be your best. But you will eventually get to the place where you won't want to buy a manufactured speaker system because you can make an equal or better one yourself for alot less. Unless they have a very complicated proprietary design that is impractical to make yourself. Great thread.
