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?

In my system, the Monitor Audio Silver 8. They're not perfect by any means, but the best out of anything under $4k that I've auditioned. They do require breathing room and quality power and don't like to be paired with bright/forward sounding amps. The midrange is excellent for the $$$. Easily better than the $5K Golden Ear Triton One in a moderate sized room.
4 Bose 901's hanging from ceiling on chains! One in each corner of room! Incredible!
Just curious, has anyone ever tried stacking Bose 901s?
I'm curious if anyone has ever added a super tweeter...with mini DSP and high passed to a couple subs, I bet these would go from fun to serious hifi.
