To test a speaker use a standard battery, 1.5 to 9v and connect to your speaker. positive to positive should move the woofers towards the listener. Most important is for both speakers to move the same way.
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...?
