Product Description

Color: Black


Experience enhanced sound from Bose's most affordable, next-generation Acoustimass stereo speakers. The Acoustimass 5 system in black delivers bass that's the deepest and fullest yet. Two single-cube speakers--smaller than ever before--are elegantly designed to fit virtually any decor. And the module easily hides away behind furniture or off in a corner, so all the lifelike sound seems to flow from the tiny cubes.

When you hear the Acoustimass 5 Series III speakers, you'll think you're listening to much larger speakers. Yet the spacious sound actually comes from two tiny cube speaker arrays and a hideaway Acoustimass bass module. The improved cube speakers offer enhanced performance, contemporary styling, and a smaller size than the Series II. And the improved module fills a room with even deeper, fuller bass. These Virtually Invisible speakers are the definitive answer to the question of how to combine spacious sound with space-saving design.

Though the Virtually Invisible speaker design may seem like a disappearing act, the performance is quite noticeable. Full, resonating bass and crystal-clear highs envelop a room in beautiful stereo sound. It's all the result of years of intense research and testing. The Acoustimass 5 speakers accomplish what no conventional speakers can claim: big, lifelike sound without big, bulky speakers. Now or in the future, Acoustimass stereo speakers can be turned into a home theater set by simply adding the compatible Bose VCS-10 center-channel speaker. For full five-speaker surround sound, add the VCS-30 center-surround speaker package.

Key Features

  • Direct/Reflecting speaker technology delivers lifelike spaciousness from a natural balance of reflected and direct sound--similar to a live performance.
  • Magnetically shielded speakers allow for speaker placement in close proximity to your TV without interfering with the picture quality.
  • Automatic protection circuitry prevents drivers from being overdriven and provides increased reliability while minimizing interference with the listening experience.
  • Syncom computer tested to ensure one of the highest levels of quality and reliability in the audio industry.

Product Description

The Acoustimass® 5 speaker system delivers the ear-pleasing music of a symphonyor the dramatic effects of your favorite movie. The Acoustimass module produces low notes without audible distortion and can be hidden behind furniture. Rich, full music and movie sound appear to come from the small cube speakers, rather than the Acoustimass module, hidden out of view. Two Direct/Reflecting® cube speaker arrays deliver the warmth and emotion of string and wind instruments. Those sounds are lifelike and spacious thanks to Direct/Reflecting® speaker technology. With a blend of reflected and direct sound, this innovative Bose® technology recreates the way sound reaches your ears during a live performance. You experience the richness of your favorite music, from almost anywhere in the room. Connect this speaker system to the rear channel outputs of your home theater equipment, and enjoy the same superb sound quality from your movies as you do from your music. You can mount the cube speaker arrays to your walls, or display them on attractive stands with our line of accessories.

Repeat, it is NOT POWERED!
The Bose is also reasonably priced when you figure in the time and money spent piecing a good system together, which may or may not sound any better.
Midnight Rider
My speaker bias is towards clean, clear sound, not a lot of mid-range and no overbearing bass.

I was having issues myself with sound quality with these speakers until I went to Bose.com and read the user guide. These speakers are meant to produce sound both directly and reflectively. If you have all of the elements pointing forward with no surfaces to bounce off of the experience is not satisfying. You need to tuck the sub away in a corner (to reflect off the walls) and the smaller speakers I find work great with one element pointing directly and the other pointing at a wall (each speaker has 2 elements). The sound with the reflection is much richer and satisfying than when everything's pointed directly at you.

Before getting into the review of my new AM5 series system, please allow me to give some background. I am 52, and have been "into audio" since my teens. I have studied classical Organ, and have a Sister who is a Semi Professional Sopranno, is gifted with "perfect pitch", and is also an accomplished pianist, and organist. I have listened to more than a few of what Audiophiles would call "high-end" speakers systems, along with the special and expensive hi-current amps neded to drive such systems. Often the experience has been pleasurable (bringing along music that I know intimatly), however I have never had an "Oh My God" musical experience, especially considering the total cost of such systems. I have listened too, and have owned (and still do) some classic Altec Lansing, J.B Lansing, Advent and KLH products. I am not "new" to music, what it sounds like live, and what is a good, and realistic reproduction.

My first advice to anyone,is to listen and compare equipment as much as you can, within your price range, on your music, and make your decision based on Your ears. If You are happy with your purchase, no one else needs to be. Our hearing Is subjective..often even "Audiophiles" will differ on their view of a component that they both highly admire. Frequency specification, within narrow limits are a benefit, but often do not actually indicate "how" the sound that is produced will "come accross" if you will. I have heard "audiophile" speakers with listed responses of 25hz-30 +/- 3db, that have had "sucked out" midbass, or midrange, or piercing highs. (Yes, they were wired correctly. I have heard many speakers with "lesser" frequency responses that sounded much more "true" and musical. Again, let your ears be the judge.

Bose seem to elicit a passsionate response whenever their name is mentioned, and I will try to elaborate on my experiences and let the reader decide if these speakers are right for them.

I currently own a set of Bose Acoustimass speakers that I purchased from a friend. The speakers were in excellent shape and I felt lucky to be able to afford Bose a few years ago on my meager salary at the time.

The speakers are definitely room *friendly*, they blend in easily as their size is unobtrusive. That said, after investigating speakers recently for a planned theater upgrade, I now feel that they are lacking.

When I first got my speakers I compared them to a pair I had purchased back when I was in high-school. I didn't know anything about those speakers at the time but was happy with their sound as well(AR Holographic M1's). The results of the comparison left me thinking my ears were deceiving me "my old speakers sound better?" Anyway, I put those thoughts away thinking that I must not understand because "obviously Bose were the best."

Fast forward a couple years, all the while the Bose were up front in my surround system with the old speakers in the rear. That whole time I had no issue with the Bose, they performed well enough. After buying a new TV, I thought it might be nice to upgrade the speakers so I would have the same brand in the front and back. And so began the research.

I spent time listening to number of speakers, including high end and mid level brands at custom shops as well as entry level speakers at Best Buy and Circuit City. I have now come to desparately desire replacing my Bose speakers.

They just sound *thin*, which oddly enough was my initial impression, the one I thought I must not understand.

Bose Acoustimass speaker systems are a strange animal. You either love them or hate them.

It's a funny thing, This guy was at my house and heard my Quad ESL speakers (electrostatic) ($5,000) with about $6,000 worth of electronics and made the comment that they sounded almost as good as his Bose.

So there you go, beauty is in the eyes of the beholder.

Myself, I'm not too keen on Bose and I could go on a tirade about what I don't like about them, but in the end, it's what you think. If they make you happy, then by God, you've made the right choice.

Bose are very colored speakers, bright highs and warm syrupy bass. This is a sound that many people like. The fact that they don't take up much room fits into many lifestyles.

If you like accuracy and want to get closer to real, then try something else.

For me, Bose has a pleasant sound that is nice to listen to at low volume when I just want background sound. I can even think of other uses for these, in non critical applications. I've even considered them for a second TV. They are much better than the speakers that come in TV's nowadays.

For the $399 they are asking for these, you could do much worse. You could also do much better depending on your preferences.

Would I recommend these? Sure, depending on whether someone wanted a small unobtrusive system or whether they liked the Bose sound. If I felt the person was inclined toward accuracy, clarity, and soundstaging, then I would steer them away from these.

Does Bose deserve all the accolades that it receives? Not really. They are very over rated, but still, they're not bad speakers.

I gave these a 3 star rating only because in some circumstances these are perfect for the application.
