Elevick, are you referring to my current speakers as far as decoupling goes? They actually have NHT's spike kit installed, allowing each speaker to touch the floor at the tips of four rather sharp spikes only. Still, I think that I would have less low end without the low 8" drivers and the large cabinet of a tower. Though again, that is only part of the reason I would purchase different speakers, the main reason being an increase in fidelity. I would also consider towers with just tweeters and midranges, though i figure I could get more for my money with bookshelves, as I am willing to sacrifice some dynamic range on the low end. I think the proacs are along the lines of what I may be looking for.
