Best room treatment

I forgot to mention if it matters that music and movies will both be important. 

I would recommend you to reach out to GIK Acoustics for a free consultation. IME, they are best in the business and reasonably priced compare to their competitors. 

Check out some of the systems here that are using their acoustic panels.

I’m under the impression that how much you use and where you place it is far more important than the particular brand of panel. Most places post the absorption specs for their panels so it’s not really a matter of better vs worse just “different”. (And of course the aesthetic angle).

With that being said, I believe Vicoustic’s analysis and room projects are highly regarded. $150 I think for them to consult on a HiFi room. Their panels are NOT cheap though (I did a consult from them and the cost for all recommended panels would have been close to $20k). GIK acoustics will do free consulting/advice, but I don’t think they’re as knowledgeable (at least in my experience). Though They were more willing to work with my budget of “around $1000” rather than Vicoustics more “we think you should spend $20k and make it perfect”

Thanks for the tips. I’ll check them them out. 

Advice, value, efficacy, selection:  GIK.

Their panels are relatively inexpensive, especially when compared to say ASC.

They have a number of products which are unusually effective at low frequencies.  These are among their priciest offerings, but again, cheaper than ASC and IMHO, sound better. They are tuned more broadly and the result, when used with care, is a more transparent response.

They also now have art panels, allowing you to get get panels to match any decor.
