@schlammorgan What an incredible room and you must be quite handy. Great job. I do not have those skills and I'm also not aiming for these Olympian peaks, so I suppose there are various tiers of accomplishment at which Foley's products and labor are more or less appropriate. My OP was really thinking about how his video was pitched at the kind of room some others have accomplished for much less, not a room like yours.
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?

Brownsfan1, Yes it is possible to purchase the carbon and possibly the plans from Dennis, but not sure if he still sells his build plans. I carefully combed through each one of his videos trying to reverse engineer everything he designed. I've figured out how to build every product he sells, putting my own design into some of them. As far as buying the carbon, I buy coconut activated carbon from another online distributor. Here is the thing, activated carbon is an wonder product. For 500hz and down, it can dramatically improve your listen experience. |
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. |
