I don't care for the rest of the plastic junk he produced, AND people actually bought it at astronomical prices...RIP. |

" So thank god most examples of the Bose 901 and its many relatives are already dead and buried. BTW: L. Ron Hubbard and Amar Bose are alike - both became famous and wealthy after starting new religions in the USA. **The 901 was based on a (very highly) flawed premise. Bose assumed (quite rightly) that most of the sound reaching a listener in a confined space was reflected sound. He failed to take account of: 1) The size of the space. 2) The reverberant nature of different spaces. 3) Outdoor recordings. 4) The fact that live recordings already possess the reverberant nature of the space within that recording. ** Don't think the design was based on any scientific premise - just that Amar liked his reproduced sound bouncing all over the place in a very live room and found others did too. He was an audio philistine of the highest order. Amar first tried to make a spherical, omni-directional speaker that was quite impractical - so a small, 5 sided box with 9 drivers was the outcome. 9 x 8ohm drivers in series parallel gives 8ohms again, so one had to go on the front as a token gesture to stereo imaging. 901s were cheap as chips to make but needed a whole lot of EQ at high and low frequencies - this is where the real design flaws began. Each puny 4.5 inch driver had less than 3 litres of box volume, so resonance went up to 140Hz. Driving a speaker well below system resonance requires a lot of extra power - 901s used 18dB worth of fit, which is an absurdity. When played at a decent volume, the intermodulation that goes on in such a contraption is appalling. Treble boost was similarly very large, cos the cheap paper cone drivers used had no tops without it. They simply had no quality with it. Plus 901s HAD to be used in a largish room and with a solid wall behind them, they did not work as intended in well damped rooms or where the walls were of flimsy material like plasterboard. Their biggest selling point was their small size and weight made it possible for wives to move then out of the way when not in use !!! Then Bose released the 360wpc 1800/1801 amplifier ( an OEM product for sure) which weighed 80 pounds - so THAT evil monster stayed put. .... Phil |

Not a commercial product, but a published design for home construction. It used a number of 5 inch woofers and 1inch dome tweeters - likely AD5060s and AD0160Ts. No stupid equaliser needed, just a touch of bass boost. Kit Sets had a pair on demo in their Sydney city store in the early 70s. .... Phil |

Not in the flesh, but I saw it in publications. Not a commercial product, but a published design for home construction.

Infinity used them in some of their early designs. The tweeters were a bit 'zingy' but a huge improvement over most of the cheap, home constructor stuff of the day. I used them in my 8-30 speakers. FWIW: A mate called me last week. He acquired a old pair of Philips MFB (Motional FeedBack) speakers. I told him that my recollection of the sound was overwhelmingly positive. Particularly for their diminutive size. He called me back to say that they are simply astonishingly good. This, coming from a guy whose main speakers are Acoustats (ESLs). -- Trevor Wilson www.rageaudio.com.au |

"Kaie Fabiaen" "Phil Allison" Then Bose released the 360wpc 1800/1801 amplifier ( an OEM product for sure) which weighed 80 pounds - so THAT evil monster stayed put. That amp worked all day and all of the night... ** Except when it didn't. I was a Bose repair guy back then, ** I must have seen dozens of them go across my bench - most with the same stupid fault. still have the schematic, and the only thing that flunked out were the LEDs. ** Not true at all. 2kohm, 3W resistors in the supply to the 15Vzeners ( for the op-amp) constantly burnt and sent the amp DC. Then there were the 4.7 ohm, 10W ones in the AC supply that regularly blew open at switch on an stopped the amp dead. Plus failed output transistors and a host of co-lateral damage. Then there was the PM2 powered mixer - wot a heap. .... Phil |

U got that right. POS with a capital P. Bose paid me night and day to run all over town to fix those suckers. ka-ching$. Not only did the 'power' section suck, but the mixer section was so lame, it sold only on the name. Owners cursed the day they bought them. Bose also made a "PA" version of the 901, that if you stacked enough of them on each side, it sounded less then ****, more like just puke. Alembic tried to sue them over the 'stacks of speakers' concept, and IMMSMW, they settled out of court. The Bose system was never at the Alembic level. Ya still see around here those Bose PA cabs..unused. I still think the new Bose 'POLES' suck and blow.. Folks buy them..
