I was attending a subwoofer demo yesterday at Practical Hi fi in Manchester. After setting up (using a 3802) and listening for a while I asked them to set all speakers to 'small', (fronts were some dynaudio floor standers that the had set to 'large'). Conversation goes something like this: Him: "Can't do that sir as it will blow up the front speakers" Me : "I beg your pardon!!!" Him: "The front speakers will not be getting enough current if you set them to small, and that will blow them up" Me : "Well that is the first set of speakers I've heard of that will blow up through getting too little current" Him: "It's because they are 4 ohmn speakers" Me : "I beg you pardon!!!" Him: "If you don't put the whole frequency range into 4 ohmn speakers they will blow up" Needless to say I suspected he didn't know what he was talking about, and after much assurance by me that if would'nt blow up the speakers the conversation continued: Him: "Anyway if you set the speakers to small you will lose the bass that would have gone to them" Me: "No, that Bass is directed to the subwoofer, and can give a better sound" Him: "No, its not, I've been demoing the 3802 for a while so I what I'm talking about" Me: "Well I suggest you read the manual before you do any more" At this point things got a bit acrimonious, he stormed out slamming the door and had a word with his boss/colleague, who subsequently supported everthing he was saying. All this on top of the fact that the shop didn't even have the equipment that I had specifically arranged to have demoed (REL Q200 and Q400). Having taken the day off and spent an hour on the train I was none too pleased. Now forgive me if I'm wrong but I thought Practical Hifi had a reasonable reputation, needless to say, after this fiasco they will not be getting my custom.
