I have had the 6T's for over a year now. I got them and a pair of M80's from Axiom in house for a comparison last year for a few weeks. I really liked the 6T's, as did my wife.
The 6T's for me are more than sufficient bass wise for listening to music, I do not use a subwoofer for music. Type of music ranges from Nightwish, Genesis, Type O Negative, Dream Theater. I had a friend over last week and we just listened to random music for an hour, and he was pretty impressed with them as well bass wise. Then I played the Peter Gabriel song Growing Up from the Up album. Halfway through my friend just looks at me asks- "Is it still just the front 2 speakers playing?". Side note- highly recommend that song as a demo for sound stage/imaging.
Anyway, these speakers work well for me.
The Axiom M80's are also great speakers in the price range, and if you're going to demo I would recommend demoing both brands if you can. It's all personal preference. I had a more detailed review on another website, I think I forgot to post it here. But here was the summary-
Overall so far, I would have to say there is no losing in choosing between Aperion and Axiom, it is a matter of personal preference, but neither speaker will leave you disappointed.
In summary, I find myself currently favoring the 6T's. Now, if someone had asked me two weeks ago which speaker would I prefer, one that goes a little deeper and loves to be played loud and is more efficient, or one that performed a little better with soundstage and imaging and excelled at the high end, I would have said give me the efficient ones that have more bass!
Now that I've been able to actually compare them, I find that what I actually prefer is not what I thought it would be.
