Summary: These speakers are exellent if they are properly placed and amplified.Room acoustic is also very inported.In first time i use integrated amplifier with 2x100w rms and i was unsatisfy with sound at higher volume levels.After that I by old Rotel RB-5000 power amplifier with 2x500w rms and the sound was fantastic! I want to recomande these speakers to everybody, in first place people in USA becouse these speakers cost in Europe more than 3000 $!!!
Summary: These speakers are dificult to drive with low powered amplifier. They need amplifier with minimum 250-300w rms to give full potentional.In first time i drive him with Sony receiver str-da 1000 es with 2 x 100w and i was ansutisfy, expesaculy at higher volume levels.After that i by old Rotel rb-5000 power amplifier with 2 x 500w and result was fantastic!
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: I bought the walnut version of these a few weeks ago, and am very happy with them. I have them properly set up, per the owner's manual, and they are pretty awesome. I drive them with a 500 wpc amp, and they never distort. They fill the house with sound, and there's no need to sit in a sweet spot to hear great sound. As for the naysayers, most haven't actually heard them, and those that have , more than likely the speaker's weren't set correctly.
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.
