I am running my T1's behind AT screen & elevated 10 inches on front stage. As a result the T1's are 64 inches above floor level. I made the mistake of locating side wall acoustic panels to low on the wall. At higher volume the T1's sounded very bright due to 1st reflections not absorbed requiring the volume to be turned down. Once I relocated the panels higher up on the side wall the change in audio was amazing. No longer bright & the sound stage was clear & concise. I actually had to turn the volume up to a higher level.

The T1's at 54 inches are very tall so make sure if they are located on a elevated front stage to align tweeters with mlp. I removed the front spikes to angle the T1's down towards mlp. A big improvement
