[QUOTE="John Roberts, post: 130883, member: 126"] Re: Opinions on BOSE 802 Series II (2) PROFESSIONAL LOUDSPEAKER ??!! Yup, I remember that. It is no accident that the 901 had 9 drivers, the sweet 16, 16, and a friend of mine back then made his own version with 25 drivers. Even squares can be wired to deliver the same impedance as the single driver. So three parallel strings of 3 drivers in series makes the same 8 ohms (4 strings of 4, or 5 of 5). Later Bose tooled up their own <1 ohm driver so they could wire them in simple series. There is some mythology (or puedo-science) associated with using a bunch of similar drivers related to acoustic gain. The marketing story about the Fender passport was that their array of similar midrange drivers was superior to other speaker approaches for the same cost. Some in the industry who should have known better actually believed it. When I was tasked with designing a competing product, I resisted drinking the kool-ade and proposed a more conventional arrangement using a woofer and tweeter. My boss didn't believe me so we built up boxes both ways and performed a shootout. My boss was heard cursing several offices away when my way won. :-) My DIY 16 driver box ended up in a dumpster eventually, but served me well playing as loud as I could stand for some 15 years. I finally replaced them with some much better sounding proper speakers. JR [/QUOTE]
