 I recently added several sound absorbing panels to my dedicated listening room. I fairly happy with the results, but the room now sounds a little dead. It is amazing what an impact these panels and bass traps have on the perception of output power. Volume positions on my pre-amp that would have driven me out of the room prior the adding these panels, are now just comfortable listening levels. I have experimented with removing a few panels, but I really think I need to add some sound diffuser panels to create a more defined approach to bringing more life back to the room. Does anyone have suggestions as to some wall mounted diffuser panels they have either used (or seen used) that might fit my needs? Thank you in advance! |

Beautiful speakers. |

Skyline diffuser panels are readily available online and also as an easy DIY project, they just take time to cut and assemble.  |

www.gikacoustics.com/product-category/diffusion-products/ quadratic diffusion .. what does your back wall look like? as a general rule 25% absorption and 25% diffusion is a good way to go.. gearsluts.com if a great site to learn about room acoustics.. your room does not look like a dead sounding room to me.. lots of reflective surface.. more corner traps floor to ceiling .. cheers

I have not treated the ceiling with anything, but the floor is obviously carpeted. As a result, I would estimate the room to be about 50% absorption materials, and about 50% fairly flat reflective surfaces. The back of the room has double (3 foot) 2 panel solid core closet doors and an entry door of the same type and size. The doors, with the associated trim, do have some surface variation that probably does a little to help to diffuse sound. The room with all of the absorption panels is growing on me as I listen more, but if I were to add some diffuser panels, where would I likely want them placed?  |

You can consider hanging some absorption panels on the door panels which will help. Most commonly, I've seen diffuser panels on the back wall.
Now it could be the camera angle but I thought your absorption panels seem to be hung a tad too high. There's a fair bit of exposed wall-space below the panels where sound will reflect from. Just a thought.

I see that you went with 48" bass traps in the corners above your speakers. When I did this, it deadened my sound too. I found that 24" bass traps did the trick for standing waves and didn't deaden my sound. Maybe you could try swapping them with the 36" you have at the back of the room as an experiment.

I tend to agree with hemster?!?!!  really? ? ,,,,,,he,,,,,he,,,,,,, Yes , I think you should also try dropping the panels behind your main speakers down a foot at a time and see ( hear ) how you like it. I think 2' drop but I'd drop it a increment of 6" at a time. Yep, Deltadube has a point as well, and defusers of some sort, the room I think needs some angles or something that acts like a defuser. Love the room, nice and clean! But sometimes a little clutter can be good. You got what you paid for from me,,,,,,,,,,I owe you 2 cents in change,,,,,,,,,,,he,,,,,,,he,,,,,,,, . |

View Attachment I would give the carpet a very low score for absorption.. yeah the front corners .. another panel from floor up be good make it floor to ceiling.. diffusion is good on back wall like hempster said.. but with corner traps.. diffusion can be mixed in to side walls as well.. don't see anything close to 50%.. maybe 15% walls x4 plus ceiling plus floors add up sq footage.. add up panels calculate 0 for carpet.. cheers |

Off topic, but I noticed that you are using a headphone amp with the Oppo 105. Doesn't that have a built in headphone amp? Curious since I plan on picking up the 105 and one of the reasons I'm willing to pay more for the 105 v. 103 is the built in amp.

I had the very same option and decided that the better sound and bang for the buck was with a purchase of the Oppo 103 and a DC-1. But that's just me. What else specifically did you want from the 105 that the 103 didn't cover. Yes balanced out would have been nice from the 103 but one of these days I may test one of the ERC's. My 2 cents my friend. |

I personally feel that the ideal setup is 20-25% absorption, 25% diffusion, and the remaining direct reflecting surfaces. I think too many people over absorb a room in hopes of getting rid of all reverb and echo. But places don't sound like that in the real world and the music isn't mixed in an environment like that either.
In my theater which I also use a lot of dedicated 2-channel, I have 2D diffusers on the walls and thick carpet/padding and ceiling clouds (absorption) at the first reflection point. Then throughout the rest of the room I have absorbing panels and diffusion. On the rear wall out Diffusers towards the side walls and absorption near the middle of the wall. I would also experiment with 3D diffusers on the ceiling directly behind the main listening position.

My 2 cents my friend. - headphone amp -- supposed to be a solid performer and I will need it to drive my cans
- balanced -- as you mentioned
- 24/192 asynch USB DAC and all other digital inputs including toslink, spdif coax
Haven't made a final decision, but leaning to the 105D. Thanks for your 2 cents |

The main reason I also have a separate headphone amp is for listening to vinyl recordings. |

I want to thank all of you for your insight. I am now working on adding some diffusion to the room, and I am also experimenting with some absorption panel movements.
I will provide an update when I am relatively happy with the resulting configuration.
