901 series 2 speakers

Optimus Prime, or original poster.

timlub, I later owned a pair of L07's.  They would have 'lit up' a 901/2 pair nicely.  Pity the two pairs were about a decade apart in my presence.

Anything nice in front of the L07's would have been merely frosting. ;)
Ah, well....long ago, and far away....*G*

Here's a history lesson re the WOS...

The 901s were the first higher end speakers I purchased. Living in the rural midwest, there were no Bose dealers in the area. So, like so many today, I relied upon product reviews from stereo magazines. One of the earliest 901 reviews was by, if I remember correctly, Julian Hersh (sp?) from Stereo Review. His impression was very positive, even a rave.  And his was not the only laudatory review. It was enough that I drove miles to Dayton to purchase a pair. My impression (no doubt biased because I had just spent, I think, $700) was great pleasure at the enormous sound stage and exciting live sound.

My point here is that based upon listening, 901 sound was enormous and fulfilling, and the reviews most positive.  It seems that when the listening experience was the only evaluative criteria, reviewers loved it. This changed some time later, as reviewers began citing disagreement with the Bose research methods conclusions, and that the the listening experience therefore had to be inaccurate. Then critical lab measurements were included in the reviews and more negativity was registered. So citing research, design, and lab measures the 901s suffered much derision over the years. But, I always wondered, why were those first reviews, those based solely upon the listening experience (including my own), generally so glowing.

The same arguments were made in a different context when tube and solid state components were compared. Why was the tube experience favored by so many,while the solid state measurements were so superior. Also, reviewers to this day still argue whether their ultimate, published judgement should be influenced more by listening or measurement.

If you are looking forward to purchasing your first "higher end" speakers, I can almost promise you that you would not be disappointed by 901s you might pick up. You will probably smile for a long time. Sure, there are better speakers. In fact I have built a pair of open baffle speakers that are the best I have ever heard, and cost less to build that a pair of purchased 901s. But you won't be disappointed. I certainly was not, and their earliest reviewers were not either.

I had a pair of AR2ax as my first speakers and they were among the early, great speakers. but in grad school was able to buy the 901I II's.  No comparison for party sound.  The 901s filled the room in a stone house with 2 1/2 ft thick stone walls and in apartments my wife and I lived in.
No accurate soundstage but Great Wall of music sound from anywhere in the room.  Seems to me they cost me $1100.  Used today for $3 - $4 hundred they'll be hard to beat.  Recommended  100 wpc but I never cranked close to that, even in the stone house.
watch out not only for the surrounds but make sure you get the appropriate equalizer.  Bouncing 8 speakers off the back walls required a boost in treble.  Anyone who says no base can't be real, though.  There is even a button on the equalizer to filter out the lowest frequency signals.  Bars and small outdoor venues would make maximum use of their 275 watt power handling turning them around to blast the back 8 speakers directly out.
if you go for them, check the sound with the equalizers.  Just like my B&O 8002 needed a rebuild because of dried out caps, the Bose equalizer needed recapping because of a serious hum it developed. I bought a used equalizer then went to the other extreme with a set of Thiel 2.4 with the Thiel SS1 sub for pure accuracy.  There's no comparison but the Thiel combined for well over $3k used v $300?  Buy the Bose if that's your budget.

I had them.... even heard them on tubes (MC 275)...

One major hurdle ... the equalizer is the destroyer of the sound.  If I were to have Bose 901's today?   I would get a Barcus Berry Sonic Maximizer and chuck the Bose EQ box. I am no fan of the 901 concept today.  But, if you have the right room and good rear walls for it?   The BBE would be a modest investment and should make the speakers sound much better.
