Summary: The Bose 901 series V is the best speaker I have heard. The highs are crystal clear and the base response is phenomenal. If you are buying used you have to aware that the foam around the speakers deteriorate. You can buy kits like I had to which is good but I opted for the cloth and actually think the foam gives a better response.
Summary: No matter how old they are Bose speakers will last forever and their unique sounds sound as good as if they were new....must make sure you have the equalizer or the difference in sound is like day/night.
Summary: I had a blown speaker and used one for replacement and it worked really great. I used it in a 402. I took alook and this was less expensive than other replacement speakers but I am 100 percent satisfied.
Summary: Bose 901 series speakers are still their top of the line speakers. when purchasing vintage speakers it is important to inquire as to the state of repair of the speakers foam surrounds. These surrounds may need to be replaced before the speaker is functional. Some sellers are not aware of this, and may not include this shortfall in their listing. Foam surround repair kits are readily available to address this problem.
Great tone and separation. A must for the most discriminating critic.

Summary: These speakers have great separation and tonal qualities sought after by the trained ear. I am a drummer so these are a great asset to my practice. I don't push these too hard due to their age but can adjust them to a very comfortable and full sound. A great listening experience awaits me each time I play my favorite music.
Durable, likely in perfect working condition, good value for the money.

Summary: First, understand that here my comments are ONLY FOR the Bose 901 series I or II. Series III and on is really a different design, ok but prone to "surround rot." (almost always needs repairs). Of four pairs I've owned, 3 were in 100% original condition and the cloth-surround drivers appeared original and perfectly working. The 4th pair had replacement drivers, competently done.
Great speakers in a small package. Beautiful cabinets too.

Summary: I never liked Bose speakers but when I heard these in the 80's with a Scott receiver I thouht they sounded great. 30 years later they sound even better. You need the equalizer to make these speakers sounds good and placement is very important. I'm running mine with an Adcom 545 and it is doind just fine.
Unmatched performance when setup correctly with the Bose 901 EQ

Summary: I have owned many expensive audiophile level speakers. For some reason I can't seem to get the ambience and 'alive' sound the 901's give me in any other speaker. This has something to do with the reflective property's 901's have. There are speakers in the rear that fire against a wall and the wall reflects the sound and becomes a part of the speaker performance.
