Adjusting for Tweeter height with monitors

First and foremost, keep in mind your speaker is a floor speaker, and your speaker like every other floor speaker cabinet is for bass and bass frequencies are non-directional, so putting the speaker flat on its base will only improve bass response. your woofers belong at the bottom of the cabinet pointing forward and not pointing up where the tweeter frequency wants to go. You have your woofer firing up at your tweeter because of the angle you have your speaker angled at, meaning you have the front of the speaker cabinet pointing up and it is cancelling out your tweeters frequency range not allowing it to reach your ears with clarity and pinpoint accuracy. Once again lay your speakers flat down on the floor with the original corner legs that came with the speakers and not that wheel assembly that is under the bottom of your speaker lifting cabinet up at the front that is causing the up-firing angle. That angle is intern causing the tweeter frequency to miss your ears or even canceling them out completely before they can reach your ears.

This is my final advice and if it does not help, I hope you find your answer. GOOD LUCK!

PEACE! TO ALL

As stated at the beginning of this thread, my speakers are monitors, not floorstanders. I have monitors because floorstander drivers would be blocked by furniture. 

You could try turning the cabinets upside down or sideways so that the tweeter is lower by a few inches.  I’ve seen speakers with the tweeter below or to the side of the woofer.  Don’t know how your Silverlines will sound those ways but it costs nothing to try.

This is a real problem sometimes. Especially for us taller individuals and then the tweeter is too low. The average height of a lounge chair doesn’t vary much. I have put as tall feet under my stands as possible.
