hilde45,Thanks! I had zero building experience when I started. Never built a thing in m life. Where there's a will, there is way. Anything for good music.
Acoustic treatment question: do you agree with Dennis Foley that $46k to $65k is required?
In a video from 1/29/2021 (yesterday) Dennis Foley, Acoustic Fields warns people about acoustic treatment budgets. He asserts in this video that treatment will likely require (summing up the transcript):
Low end treatment: $5-10k
Middle-high frequency: $1-1.5k
Diffusion: Walls $10-15k, Ceiling: $30, 40, 50k
https://youtu.be/6YnBn1maTTM?t=160
Ostensibly, this is done in the spirit of educating people who think they can do treatment for less than this.
People here have warned about some of his advice. Is this more troubling information or is he on target?
For those here who have treated their rooms to their own satisfaction, what do you think of his numbers?

Bull schlockey. He's selling treatments at unnecessarily high expense. If there is a need for room treatment (pretty much EVERY room).... Get a bunch of 5-foot artificial ficus trees. ~ $40 each from At Home (home furnishing store). Fabulous diffusers. Carefully spread the leaves and bend the branches so that they roughly parallel to the floor or maybe pointed up a little - like a REAL tree. Place about 2/3 of them behind the speakers, slightly out from the wall behind the speakers and between the speakers. Use two, one on each side, to take care of mid- and high-frequency wall bounce. Put a few along but not against the back wall. For less than $600, the room is full of attractive diffusers. And they won't drop their leaves in the autumn. I'm using abut 15 5-foot artificial ficus trees.in my listening room with quite excellent results. Others have reported similar results. |

shalommorgan, Very impressive, looks smart and purposeful. Did you measure the room performance as you were adding treatment? @ pureaudio, wow, I am appalled at the good money you spent and without the reward. I sympathise. Re: Denis Fooley, what can I say? @ hilde45, I did offer a gentle warning about the above gentleman. It is really not necessary to pay that much to transform your room's performance. DIY goes a long way in keeping costs down. My 2 bass traps cost me about $220 Just these 2 made a huge difference but measurement shows that I need at least 1 more. @bpoletti. your dust collecting ficus trees unfortunately can not in any way address low frequency problems. Fact: Lambda = velocity divided by frequency, so a 40Hz wave is 343/40 = 8.58m, over 28ft. long. At 20Hz it is double that length! In the photo below is the start of a bass trap, built from cheap construction timber, plywood and rockwool, the closest equivalent to OC703 I could find. https://imgur.com/Lwx8NTR |
