They were JBLs and they were old, so I bought them, but they have some serious problems. The 10"s in my SVA2100s seem to be able to reach up to the tweeter's low end, but not these. These speakers are begging for a lower crossover point or a midrange driver. There is some serious bass coloration as well. The top end sounds pretty sweet. I'm going to keep an eye out for some L46s or the really small ones because I like the design and the build quality of this series. These might be good for my son's dorm room this fall.
