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

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?

I’m sure it can cost that much. Like most things of course it depends. Big time. 
I agree with Mapman.

I think overall those prices are too high, but it depends.  If you are building a room from scratch, and looking to incorporate bass traps in it, and the like, then those prices are right. 

However, no, GIK makes great products including absolutely wonderful bass traps that you'd be hard pressed to treat a modest living room and spending more than $10K.
My own living room will end up being around $3K, see pictures in my system.
I've measured speakers in my living room flat down to 100hz using no room treatments other than sofa ,  drapes, bookcases etc.. room treatments are necessary in some spaces but I think people overdo I don't like a dead room some reflection adds spaciousness. 
Thanks, guys. This video is indicating that these ranges are designating the *minimum* amounts one needs to spend to get any real improvement.

I’m trying to read between the lines, here. I suspect that Foley is either (a) tired of dealing with customers not willing to spend much at all or have unreasonable expectations or (b) is trying to acclimate his potential clientele to spending a lot of money with his company. Or both.
