Howdy folks, I’m drawing up plans for a detached dedicated listening room.
Concrete flooring, non parallel treated walls, false wall for cable management and gear storage, etc. Probably will put about 100k into it. Wife won’t know that budget. 😉 I’m very much undecided on dimensions. Anyone have any experience with this sort of project?
I have a slew of equipment, and I love to switch combinations. Ultimate goal is a room to fully appreciate everything from some klipshorns to a small set of bookshelves. Couch, two chairs and a coffee table. I can’t wait!
You want a rectangle with symmetry…that non-parallel walls help is a myth.
Non-parallel just shifts the modal frequencies a bit…they aren’t eliminated.
A larger room will have fewer challenges to deal with.
When you make a room asymmetric you spread the modal frequencies to avoid one big fat periodic mode. It’s not a myth, the bridgewater hall in Manchester is a great example having thousands of flat facets and no parallel surfaces in it.
I guess my suggestions would be to nail down some factors like Atmos / no Atmos, windows / no windows, people to seat = few vs many, and DSP options such as Dirac ART, Genelecs system, Trinnov, or others. That will help inform some input parameters.
But if I grasp your idea, more a high end listening space and not a home theater, then I’d recommend an acoustic design firm, plus an architect, plus a gen contractor, and work thru the budget splits such as 30k equipment 45k build 10k electrical & lighting and 15k for the designers, architect, permits and furnishings.
On dimensions, I’d suggest a non-box. Something with a wedge shape horizontally or vertically to help with modes.
If you like to read up, there are some good info in Toole’s book and other books on recording studio design.
Contact Russ Berger at Russ Berger Design Group of Gavin Haverstick at Haverstick Designs if you are expecting to spend that much. I know them both and they are pros.
