I have a pair. A small room, 11x12. I drive them with 60 watt tube mono blocks. As for low levels, don't really know what your 'low' is. Typically I play mine at 75-80 db. Great sound. I also have a pair of ProAc 140's and they also are tubed. My room has been extensively treated so it is on the 'dead' size. Mostly play small combo jazz, vocal and instrumental. In the end the only way to tell is to buy a pair and put them in your chain. Since the 1sc's are always in demand, you can always sell them off at little or no loss.
