High accuracy midrange is (to me anyway) important, so I tend to prefer smaller drivers (no offense to Serge, my valet). I have some Silverline Preludes (a bargain...trust me) and an old REL sub with the beefiest 10" I've ever seen. By dialing in a proper amount of bass (that amount changes from recording to recording it seems, as does my taste, mood, and earwax buildup) a little magic can break out. "Serge...my dancing shoes please!"
