This post is aimed at Ian and Andrew but others are welcome.
I’m building a combo HT and 2ch listening room. My thinking on the ALFRs is that they need a untreated front wall from behind the speaker to the side wall and untreated side wall from a few feet in front of the speaker to the front wall but I’d like to verify that.
What I like to know is if putting diffusion between them (behind the screen) is Ok.
Same goes for the absorption at the first reflection.
Guess the discussion I want to start is about treating rooms with active LFRs …
Given the nature of the LFR to send sound off the backwall, i've not put any thought into adding anything for sound purposes in those locations. Am close to getting a diffuser for the side wall opposite our curtained wall though (an acoustic felt product). Hopefully will have time to finally tune all the system in and measure it in the coming weeks, though a channel in our Axiom amp went dead so i have to get that resolved.
