I see, yeah JBL 4311s are considered to be one of the best. The weak bass can be augmented by placing these speakers further out into the room (I'm able to hear the bassline in Beastie Boys' Intergalactic), but don't expect chair-moving bass from the SM300s... these are panel speakers after all, they're not designed to thump. I find it interesting that you say these speakers sound "dull", the last pair of speakers that I heard that was "dull" was a pair of Infinity Entra Twos, they sucked in my stereo steup. The Sm300s seem to sound pretty good with jazz/classical music and have a bit of prominent emphasis on the midrange, kinda reminds me of my old Advent Large speakers with the fried egg tweeter. Its sweetspot is rather large since the panels that are producing sound is so large when compared to a normal woofer/tweeter. I've had two different pairs of Cerwin Vegas, one is an E-715 and one is LS-10 and they don't sound anything like the SM300s, they're house party speakers... loud and more loud, IMO they sounded dry in the vocal range and has a fairly anemic soundstage, very impressive bass response though.
