When is a Listening Room Too Big


I've always considered the interaction of your choosen speaker and the size/type of listening room to be step one in getting the best sound possible. A speaker too big for your room will overload everything and ruin the sound, a small speaker in a really large room might only work well with nearfield listening.

Here's my question; when does a listening room become too large? Lets say you have a nice speaker like a Magnepan 20.7; my current room is 17.5 w x 26 L x 9 h. As I design and build my next dedicated listening room, what dimensions should I aim for? Is 21 w x 31 L x 10 h too big?

Paul Klipsch always said that the best measured rooms typically fall in a range where the width is around 67% of the length...

I wonder about a larger room just for that reason; scale. It's harder to convince yourself that Allison Krauss and Union Station are standing right in front of you when your room is 'small'. I think that all the Maggies are capable of amazing realism (especially the 20.7's) but if the room is too small it doesn't truly work to its total potential. If I had a smaller room I would get 3.7's...or a different speaker.

I may actually have the opportunity to build a new room once I retire (not that far away!) and it will most likely be the last one for me... I'm thinking that another 3 to 5 feet, say up to 22 ft or so wouldn't hurt.

The amps I use now are plenty of horse power for my current room (Cary 500 mb that double to 1,000 watts into the 4ohm load) but maybe they would not be up to task if the room got significantly larger... Wonder if there is a 'mathematical' way or rule-of-thumb for estimating power currently used vs what you would need when the room gets larger?
