@dbphd ,
Because they are not rear ported they can go much closer to the wall than your Reference 1’s and like @yyzsantabarbara said, they have DSP, so you can set the sound the way you like.
All the best with your new speakers.
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.
