Tritrix are better than the Overnight Sensations. The overnight's sound as if a blanket is thrown over them compared to the tritrix. The tritrix tweeter is so much more revealing, clean, clear, etc. Because of the numbness of the overnight's high end it seems to accentuate the boominess in the low end and you get a dull and boomy sound compared to the tritrix.
Now we thought the Overnight Sensations were a good little speaker in my bro-in-law's house when we listened to them and nothing else. Once we did the comparison though, it was clear that even though the overnight's may be good for the money, the Tritrix were definitely worth the additional cost in parts, build complexity, etc.
All of this is of course my humble opinion!
Wow, haven't been on the forum this long since December...feels good to post something.
