Does the first reflection point actually matter??

I agree with the frequency region he focuses on.

We see that serious acoustic treatment is expensive. That seven thousand dollar figure is an argument for taking loudspeaker/room interaction into account from the beginning, as imo there are more cost-effective solutions.

A dedicated audio room is way much cheaper to treat and controls....Mine with 2 windows relatively small with irregular geometry, cost peanuts and the results are astounding, superior to many upgrading of my gear...

But a living room, being a common room ask for more esthetical solutions, then costly indeed....

My own room look like the seat of an arachneid that will use his many "fingers" to connect all with his silk cables.... :)

i could not do that without divorcing in a common room....

And like usual people never speak about active room controls of acoustics, only about passive materials treatment.... I begin to think that i had invented the concept..... It seems nobody has ever hear about it all...But active controls cannot be done in a common room anyway...

Thanks Duke. Your feedback is ALWAYS appreciated. As you know I seriously took the room into consideration when make the speaker decision, turning down several planars /dipoles that i was really interested in. The Harbeths, 3 feet out from the front wall and almost 7 feet from the side walls, with their large front baffle seemed to be the best choice and quite frankly they sound absolutely amazing, BUT Foley tells me the Harbeth midrange and the speaker overall will sound like a different speaker altogether to the extreme.

Soooo... now I’m deciding on putting 1200 lbs of treatment in our main living room but save multiple x $$$$ on the cost of a wedding next June since my fiancee will surely leave me. Not an easy one indeed. 🤔

This is why I always recommend GIK acoustics. Very effective products at reasonable prices. I don’t know of any of them that weigh 150 lbs either. :)

As an alternative, consider the GIK panels with soffit traps, which are cheaper, lighter weight, and also go down to low frequencies. They also do free room consultation.

Truthfully, you may NOT need any bass treatment, so panels that go down to 40 Hz may be serious overkill. Tame the mid/treble range, and this may re-balance your room well enough. If that doesn't make your speakers sound larger and more powerful, then pull out the bass traps (GIK soffit). 

Also, might want to try using excess toe-in. Have the tweeter line cross in front of your head. This may sufficiently improve reflections off the sides. Of course, heavy curtains would also help.

3. No need to buy software to measure the room since the problems are obvious and better spent on product.

What? I am not considering my self as a measurement guy. But that is the just so wrong on so many planes.
It is like saying don't give someone else money but instead give it to me.
On the other hand not many buy the software when it is free.. on the third hand you need only buy a calibrated microphone that cost peanuts (65-100 USD). 
You need to learn to use the software or get someone that can.

Nobody trust me nobody can hear what you are able to find out by measuring. (You have never heard someone say "Oh that room has a 10 dB big dip at 53 Hz" for example. But measurement will show you exactly that and much more)
You can determine what effect after that you got after putting 7000 $ into your room

1. You should see on your measurements that your decay times is considerably lower over the whole frequency band.
2. Less amount of peaks and dips

How do you quantify that the sound after you spent 7000 HAS got better? Are you and Foly sitting in your sofa and subjectivity nodding to each other and saying "yes it sounds better.."

It is like emperor new clothes nobody dear to say something negative..

Plus he knows that if you don't do a measurement then you will not after the treatment say to him "Look there is still a 10 dB gain at 100 Hz (for example) after the treatment as it were before..

Plus he knows that if you get the gear and make measurements with the free software that you are halfway to be able to make a active correction.. you need "only" to take that measurement and export and then import to the DSP for it to correct your room..

To push you into that direction is only loose loose for him. When you can make demands on how much improvements you should and would expect..

But yes I am also of that opinion that we should fix the room with room treatment as far we can do THEN using active DSP.

But you NEED to measure to have and to get a baseline..
Measuring is knowing! 

(On a personal plan I think you will destroy that beautiful space. With all of those windows there is not much space to put all the stuff.. and making that project very hard from a esthetic point of view.)
