Here's a good one... I was recently auditioning 4 different brands of speakers at four different Hi End A/V outlets in town. These dealers all carry brands like Lex, P-Elite, MacIntosh etc... (no Kenwood's!) In one store, I was considering a THX certified speaker set with side firing powered subs in the mains. We sat in the room, threw on the Matrix (bullet time and helo crash scene), and I was Hugely impressed in how these smallish towers and the bipoles filled the room. I also noticed there were in wall speakers in this room in addition to the setup being auditioned. These were both at the front and rear. Between scenes, I asked casually... "Are the in-wall speakers firing too?" The salesman stated indeed, "for this set-up they are linked in series as well." I didn't blink, and listened to the end. I thanked him and went for Paradigms (AT ANOTHER DEALER).
