Al, you can disagree, but remember he is talking about Magico speakers, not other brands. With what do you emphatically disagree, that this is Magico's opinion about the use of subs with their Mini 2 and Q1 speakers, that this is what he told me, or more generally, the use of subs with monitors? He is not suggesting what you do with your brand of speakers, that is your business. He is just recommending what sounds best in his experience with the monitor speakers he designs. He told me that a fuller range Magico speaker will sound better than one of his monitors with subs.
Obviously I am not the only one who disagrees here.
