...let’s say for a medium- to med/lrg- sized room...
...no need to worry about sound treatments or power conditioners, let’s assume that’s taken care of...
Would love to hear what you would build and why you would build it. If it’s what you already have built, great. Share why you love it.
Thanks in advance for any of your builds :)
