Ideal design for a new music room


I'm designing a new house which will include a room dedicated to enjoying stereo music reproduction. In my experience, room acoustics have a huge effect on the sound in any particular room.

I'm interested in ideal dimensions, structural materials and finishes. Any experiences and stories anyone?

The music I mostly enjoy is classical, including organ, choral, chamber, solo instruments and orchestral.

Find Mike Lavigne system... Mike can tell you how  the room was done... It’s the best....
Hi,

Yes indeed, Mike Lavigne has the ultimate stereo listening room. A wonderful article by Matej Isak - Publisher, Editor-in-Chief, Founder & Owner of Mono & Stereo, has a detailed description of all the considerations that went into its design and construction here: https://www.monoandstereo.com/2018/04/the-audio-system-and-high-end.html.

Thanks very much for the reference.
OP- purchase Jim Smith's book Get Better Sound. Best $ ever spent for this sometimes crazy ridiculous hobby.

There is a comprehensive article regarding Robert Harley's experience on this topic in the latest Absolute Sound (April 2019, pp 28-40) -- quite a detailed discussion and having had my room built to the same technique (albeit with the full on glue approach) I can endorse it -- and if you have the time and skill you can do it yourself
