@dbphd Bass management and crossovers are two different beasts, and one is definitely not a substitute for the other. The only exception to this is that most AVRs bass management does crossover as well as level and EQ.
KEF LS60: Distance from wall behind them
I'n most of the video reviews of the KEF LS60 I've seen, the speakers appear to be quite close to the wall behind them. I realize they are not rear ported, but is there a recommended minimum distance from the wall behind them. They will be replacing KEF References 1s that are 45" from the wall behind them.
