Yes, they are good, not the best I've heard and from what I believe the L'acoustics standard for live production is still going to be the standard. Either 2-4 Dvdosc or 2-4 Kara over the Sb18 its still the best low profile pound for pound best DJ mon system out there. Especially with LA8 processing and amplification.
