Speakers sound too bright.


I just bought a new pair of Martin Logan 60xti speakers.  They are too bright and fatiguing.  I would like to avoid returning them.  I've tried toeing them in and out.  I cant get them further than 1ft away from the wall (back of speaker to wall).  I have a about 1-2 hrs of play time on them.  Not sure if break in will help settle the upper frequencies down. Any suggestions...?

How do you know if it’s just your speakers or any part of your system contributing to this sound? For example, if you use a Benchmark dac with any speaker, it will sound analytical/shrill. 
System synergy is more important than any 1 piece, after the room of course.

I had the same experience with the XTi60's and could not mitigate the brightness. Good ribbon tweeters cost money and quality can vary a lot. The ML's are perhaps a bit too much of a bargain.

I found the RAAL tweeters in the Ascend Towers to have a similar footprint and much better performance. I recommend Ascend.

I agree with many here that your room is probably your biggest challenge.  I have the ML Motion 60's, and actually focused the other direction.  I added a pair of small, sealed Subwoofers (SVS SB-2000) and it was the best money I've ever spent on audio.

For everyone pointing at the room, I tend to agree that is a weak link. But the OP has stated that the KEFs didn't exhibit this behavior, so the room and the equipment are the constants in this scenario. Room treatment will certainly help any speaker perform it's best, but that might be the primary issue here.
