Thank you for the quick reply and things to consider.
Assuming you mean more than tape measure measurements, how would I best go about measuring my room?
my system sounds really good, not harsh I have a record storage bookshelf about 18” behind speakers the bookshelf is against the front wall
im new to this level of consideration for my listening space but want to maximize my enjoyment. Is there a good read on this or acoustic panel company that can guide me?
