From what i was able to find out, the individual drivers for each Dunlavy speaker system are matched to within a .25 dB tolerance. That is a LOT tighter than the 1 dB that was previously posted. As such, i have to commend ( a little too late ) Dunlavy for being so picky about their products. On the other hand, this would make it near impossible to find a suitable set of replacement drivers should you ever need them. At 50% off of list price, these truly are a great buy. That is, so long as you don't need replacement drivers, etc... Sean
