My hearing hits a brick wall at 1.8Khz. I do love bass as it's about all I have left. If most dialog is at or below this, could sound treatments help? If I have correct information, much dialog is in the 2 to 3Khz. area. Wish I could find a demo place to listen to room treated properly to tell what this may do for me. Should I pursue room treatments? How do I decide? Any Idea's?
