Speaker are like cars, you have these audiophiles who will tell you what is best and why one is better than the others and totally forget the fact that most people would never experience and lack the knowledge and appreciation to even know the difference.
I have a friend who is a real audiophile and still listed to his music from vinyl since he claims the sound is more pure. He will sit there and tell you how much better and show you how each sound different, problem is unless you have a trained ear you will not hear what he is talking about.
Most people, including me can not hear the things these experts are claiming are important. If you can not hear the difference do not pay or buy it or just buy what you like as you would do with a car.
I do not think anyone would argue that with enough time and money you can put together a system which will out perform any Bose system. However, if you are not a sound engineer or have a trained ear, buy what works for you because you most likely will not be able to tell the difference.
To refute a couple point this guy made on that website, to back up my point, he talked about how the Bose do now work from 20Hz to 25KHz, true but why do you care, he is trying to claim even if you can not hear it you body some how does, interest claim. However here are the facts, and you can look this up, and I can tell you my son did project on this as well, most people can not hear above 15K actually it is age thing the older you get the higher and lower frequencies drop off, kids under 18 can hear 17KHz and up to 19KHz and the few odd ones can actually hear 20KHz, once you hit around 18 or so your ability to hear above 15K decrease quickly. So if you can not hear it why speak money trying to produce the sound.
He also attempted to state that if you listen to music which covers the entire range you losing the highs and lows, again who cares, most music people listen to do not cover such a large range, why because most people can not hear it so most sound engineers do not bother.
Then this person went into what the speaker are constructed of, again who cares and plus he is making statements of fact and does not back them up other than to say it look to him. Did he actually go out and tear all the various speaks apart and send them to a lab and have them analysis, of course not, he just trying to make a point they some how use cheaper material then anyone else. Not sure how much that is true. The best comment was that the speaker box allow emission of EMI and Magnetic field. Yeah all speaker do that, very few actually put shielding of any sort inside them, again who cares, unless you put your speaker next to an old tube TV the magnetic field are not an issue nor is EMI. EMI is only an issue in the 100's of KHz not on the low end.
As with a car go test drive them and stop listen to the experts, because you will end up buying something that cost more, and you can not tell the difference. I test drove a number of speaker and went to sound rooms at a audio store and for the most part I could hardly tell the difference. Bose can fill a room with sound as with many speaker the interesting part is you could hardly tell where the sound was coming from. I know this is what bothers many experts, because the make the comment they want to know and feel where the sound is coming from.
I will tell you this much, generally a package deals are okay if you do not have the knowledge or skills to piece it together yourself. However, Speaker tend to last far longer than the electronics, so my personal view is to separate them, buy good speaker that sound good to you and buy the electronics that meet your needs and update them as time goes on.
I have a couple of speaker systems in my house, and I still like my Bose and they are 20 yrs old so they are not the complete system. and they sound as good today as they sounded when I first got them and they are smaller than any of my other sets and sound as good and I never had any one come to my place and said they sound bad or horrible other than my audiophile friend, but that is a personal issue of his.
