Hi Audio Experts! My dedicated listening room project is coming along nicely. Its to the point now where I need to start entertaining the idea of a room treatment plan. Currently finishing up the second layer of 5/8" drywall. Its been interesting to see how dead a framed insulated room is and see how it transforms into an echo chamber when it is all rocked up. Having never treated a room before, ive been getting myself all confused with all of the treatment threads i read. Looking for some advise on how to start. Ethan, I am also open to purchasing some of your products along with the possibility of doing some DIY treatments ( corner bass traps?) Here are some of the room basics: 14' Wide 20' Long 8.5' High. Thanks for the help. Erik ![]()  IMG_1561 by vego99, on Flickr  IMG_1562 by vego99, on Flickr |

Cool space with good dimensions. Is that door going to be behind you? By all means, get a quote from Real Traps. Barring that, budget, available materials, time, and dedication are your variables for diy. Basically, you'll need corner treatment and an RFZ. The rest is details. I suggest taking an acoustic measurement once the room is finished and empty before putting anything else in it.

Thanks Hexspa! Yes the door will be behind the listening position. I have been trying to do some research on corner treatments but not sure which way to go.. Ive read doing normal corner placements of RFK Faced 703/705 and I have also read people cutting 703/705 into triangles and lining the corner from ceiling to top. At one point I have also read taking bales of fluffy fiberglass and placing them into the corners with the plastic still intact... Not sure if this is the cleanest approach.
Good idea on the measurements. Assuming everyone still recommends REW? I have the program but have yet to play around with actuall measurements, need a Microphone to get started i guess.. Any suggestions on USB mics? Ill be using my MacBook.
Thanks again,
Erik

With DIY treatment, filling a corner completely with triangles is a little better than having thick panels straddling the corner. But it costs a lot more. So if buying 2-3 times more material to get a 30 percent increase, then that is the best approach. But if cost is a concern, you'll do better to spend your money elsewhere. (My 30 percent increase is a guess because I never measured it. But it's probably something like that.) What's behind the ceiling soffit? If you have metal air ducts lined with fiberglass, you'll be better off removing the sheet rock. Unless you need the sound isolation, in which case never mind.  |

Hi Ethan,
Ducting behind one soffit, iron beam behind another. Isolation is primary key with this room to prevent waking up baby and wife during light night listening sessions.
How would stacking triangles of 703/705 compare to your MegaTraps. I would assume your megatraps would look cleaner, yes?
Panels on reflection points, given the size of the room, would you still recommend these or lean toward diffusors?
You mention cost concerns and spending money elsewhere.... Yes cost is a concern to a degree weighing in doing it correctly / time spend / effectiveness vs. Purchasing a item that is already designed and tested.

Yes cost is a concern to a degree weighing in doing it correctly / time spend / effectiveness vs. Purchasing a item that is already designed and tested. FWIW, I have 20 4" 8lb mineral wool panels and 9 31"x4' super chunks made from fluffy. Total cost: about $600. DIY can be as beautiful and functional as resources allow. The minimum and maximum amount of treatment will depend on your aims. That also goes for the decision to use diffusion. I think it's time to be specific. What is your experience level? What are your goals for the room's use? How much are you looking to spend? How much time do you want to invest in setting up the room? How much are you willing to learn? How comfortable are you with your knowledge and DIY skills? Answers to those questions can help us help you. |

Hexpa,
Experience Level : As far as what?
Room Goals : This is a dedicated listing room housing my stereo equipment and records. I would like to have a listening room that provides enjoyment, good sound and minimized listening fatigue.
Budget: great question.... this is subjective. I've got about 5k in building this room so far. Do i want to spend another 5k on room treatment. Not necessarily. This is not a professional recording studio nor do i have 100k worth of sound equipment in the room. If possible Id like to try and build my own treatments but if buying professional treatments outweigh the time and effectiveness of
DIY treatments then I would consider doing that but I may need to go in stages.
Time Investment: I am open to investing the time needed to set the room up.
Education: I am always open to learning new things.
DIY skills: What you see in the pics started as a blank slate in my basement. All DIY so far.

Since your room is permanent and purpose built, I suggest permanent, built in corner traps. I feel it's easier and cheaper to install batons on the wall across the corner and top and bottom, install insulation, cover with fabric and finally install trim to hide staples holding fabric in place. (I've outlined this before in other posts.) You can also do this in "pseudo sofits" at wall / ceiling junctions.
For RFZ, you can install 2x8" (or 1x8s") floor to ceiling and fill with insulation and cover instead of building or buying panels and installing them. You will need to support fluffy with internal wires.
This method has pros and cons but if you like framing and working on a larger scale rather than building many smaller panels and than installing them, this may be for you.

DIY skills: What you see in the pics started as a blank slate in my basement. All DIY so far. Pft. If you built the room then you can make acoustic treatment. The rule of thumb is to have 10x the commercial value of your speakers in acoustic treatment but, clearly, DIY is likely cheaper. I like rock's permanent install idea. Though remember that more absorption is almost always best so, unless you need the floor space or intend to place your speakers right against your treatment in the corners, soffits will be more effective than diagonal corner traps. There are a lot of details regarding placement, thickness, and material choice. Definitely get your measurement done asap. I don't know any USB linear response condensers but you can get a cheap Behringer interface. I use the ECM 8000 for a measurement mic. Hope that helps. |
