Summary: I did have a pair of DALI-IV and the foams were damaged. So I was looking for a pair of speakers and come across the BOSE 901(IV). I got to say I was first attracted to it because of the unique design. As I do more researchs and reading regarding to the design - It sounded good - So I bought an old pair from the trading post.
Summary: These are not audiophile grade speakers. What they have is a super- midrange that reflects everywhere- not good for imaging or soundstage. Perhaps they are good for home theater, where sound effects are more important than two channel realism. Don't get me wrong- I loved these speakers for many years.
Summary: Hello stereo heads, Bose has been making 901's for quite some time. And they have done it well. It seems that the biggest complaint is that thumpers or bumpers, whatever you want to call them, want a lot of bass. I think I may have the answer for you. I have a pair of Bose 501's that I use with my series 6, 901's. You can have the best of both worlds. I listen to everything from the 40's to the 70's and beyond.
Summary: I am using 901 series 4 as rear channels and series 6 for fronts and the Bose 802 1995 Model as the center. And a yorkville 200p power sub. The bose fill the room . Every seat is a good seat. On the movie Loin Heart where dragon talk off screen and fly over head will show the true sound of being engulf in sound. Because sound is bounding off the wall you will not pin point which speaker sound is coming from.
Summary: OK, I'm going to give my view. I've ready many owner and expert reviews on many speakers (901, B&W, MBL, etc). I've listened to many, many "high end speakers". Out of about 5 years of effort, I found one consistent truth. Each lisener has his/hers own subjective preferences. I've taken a physics approach (my background). From this perspective, the 901's are certainly unique. They try to optimize electronically to produce "live" sound.
Summary: Hi Folks: Well I thought I would weigh in. I had a pair of series II's for about 25 years and enjoyed them everytime I listened to them. I got a pair of VI's a couple years ago and sold my II's to a friend along with The Carver Receiver. He loves them. Of the people I know that own these speakers, including myself, they all aquired them because they heard them at a friends house, and were amazed at the large, quality sound coming from such a small package.
Summary: I have a set of Joseph Audio Infinite Slopes...series II. They crank...so do my Bose 901's! All this crap about how Bose 901's are junk....I think these guys either can't afford a good set, or don't have the right spot to place them....like appartment...........BIG PROBLEM...if you want to crank it up!!! 901's Rock!!
Summary: I purchased a used set of 901SeriesVI with stands and equalizer for $600 and have been using them for 9 months. My room is LARGE at 1850 square feet. This room has unusuallly good acoustic properties. I am driving these speakers with 120 watt Sherwood and SVS dual firing sub. The sound is quite good , couldn't ask for a better fit in the room. The reflected sounds is great at all sound pressure levels.
