On the idea of using a sub, I had a sub at one time, can't remember which model, but it was a PSB, and I was able to improve the sound considerably. So, I'm not against the use of a sub at all. The thing I didn't like about the sub was I had to keep adjusting it all the time. I seemed to have to switch the crossover whenever I changed from orchestra to choir to classic rock, and fool around with the volume. Remeber, I have a 9x11 room as I suspect that may have had something to do with it. Overall, I liked the sound better with the sub, but I just got tired of having to adjust all the time. So, the question would be, if I get the right sub, with the right room set-up, will I be able to keep the same settings without all the adjustments?
