The best speaker you ever heard?


In my opinion, the speaker is by far the most important part of the audio system. After all, it is the only part you hear. OK, the other stuff really matters a lot, but without a great speaker... No go.

I am a bit 'speaker-obsessed' I guess, and now I am wondering: What are the best speakers you have ever heard, and what made them the best?

From Bose site: Today, thanks to Bose electronics research, our 901 speaker system incorporates some 350 enhancements over the acclaimed original.

That's alot of enhancements.
One of the MOST IMPORTANT things and most overlooked things with the Bose 901's is using really good interconnects and speaker cables with these speakers. This is just as important with the 901's as speaker set up is ! I think a lot more people would like these 901's if they would just use better cables with these speakers. You are never going hear the full potential of these 901's until you use better cables with them !...
Ok everybody gets it, you like Bose, now lets move back to the best speakers you ever hear topic!!
This is getting boring to hear you talk about the 901s. Start a separate thread if you wish.
Has anyone heard the new CHEAPO modified sony SB 300 that dakiom modified (known for the feedback stabilizers)? It just came out. Though what they did with the INTERIOR seem to be an achievement. They claim it's the best speaker out there and challenges anyone who can out do it? At $1595, I am not so sure of trying the 30 day return policy for a CRAP sony that was sold at bestbuy a number of years ago which I bought and ended up in my niece's home awhile back ago. I can't justify any audio engineer wasting their time modifying a cheapo and sell it at that price point. I'm sure it sounds fine with all the new patents and unique modification process, but to claim it's the best speaker out there is kind of stretching the imagination and what about the WOW FACTOR? Even someone who is a diehard dakiom fan who has a significant other, takes home a speaker like that and spends that kind of money is going to be frowned upon just by looks alone. I am just curious if anyone heard it or tried it. To me modifying a cheapo like that without modifying speaker drivers or cabinets is like spending hundreds of thousands of dollars on a volkswagon bug and think it can outrun and outdo a lambhorgini countach is STRETCHING their claim a bit?
Best speakers I've heard are my ess heil 1D that I modified removing the passive radiator and switching the FRONT driver to the rear and adding to the front a pioneer subwoofer. With the right electronics, it does what magnepans are known for and does the reflective principle that bose attempts to do but with real dynamic bass, not a fake muddy one that bose does. It's kind of a toss up for me, between my eminent technology lft 8a and my ess heil 1d.
