Question about absorbing first reflections with Revel speakers
I have a question for all the Revel owners out there.
I just recently purchased a pair of Revel f208s. In my listening room I currently have a number of 2-inch fiberglass acoustic absorbers along one of the side walls. I don’t have any on the other side wall (I’m not able to put any there because of how the wall is shaped).
I’m wondering if it makes sense to keep all of these absorbers up with the F208 speakers. I’ve read a lot of what Dr. Toole has to say on this subject and my general impression of his message is that acoustic absorbers should really only be used for speakers that have uneven off-axis response. For speakers that have even off-axis response (like the Revel f208s), acoustic absorbers could actually alter the evenness of the off axis response. So, they could actually make a good sounding speaker sound worse. And this can be especially detrimental if you are using acoustic absorbers on the first reflection points.
However, I have read Dr. Toole also saying that the testing on this subject has also noted that there might be a correlation between people’s preferences and the type of music being played. With modern pop or rock music, many seem to prefer absorbing the first reflections (even if the speakers have even off-axis response), but for other types of music such as classical many seem to prefer not absorbing the first reflections.
So all this got me wondering: should I continue to absorb the first reflections in my room with these speakers? I listen to mostly heavy rock / metal (bands like Tool, Mastodon, Animals as Leaders, Nine Inch Nails), so maybe absorbing the first reflections is the best way to go?
Note also that I mentioned above I only absorb the first reflections on one side wall. The side wall that I do this on is about 2 feet from the right speaker. However, the other side wall is about 6 feet from my left speaker (it’s a bit of an open space on the left side). I noticed in one of Dr. Toole’s write-ups about his own room that his set-up seems somewhat similar in the sense that he has one side wall (to the left of his system) and an open area (to the right) and he mentioned he uses thick, heavily pleated velour drapes to absorb the first reflections on the left side of his room.
So, based on all this, I’m thinking it might make most sense for me to continue absorbing the first reflections on the right side. But, I will certainly experiment with this. Anyone here have any thoughts on this?
