I don’t agree with this one, especially as relates to bass, but what do I know?
This fact or fiction question is an interesting one because the notion of matching speaker size to room dimensions is so ingrained into our culture as to be taken for fact. But, some facts aren’t true no matter how much we want them to be.
Here’s the deal. Any size loudspeaker will work in just about any sized room. The exceptions are easily found with common sense: no, a pair of bookshelf speakers won’t work in the Astrodome just as an IRSV won’t fit into a closet.
As long as we’re on the same page with respect to common sense, let’s take a look at where these ideas came from.
Our natural human tendency is to match object size to the space they occupy, which is why a small dining room table in a big home looks out of place, or a king sized bed hardly works in a tiny room. But it’s our visual sensibilities that are at fault here, not the size mismatch. In fact, for a family of two with the occasional visiting couple, a 4-seat dining room table is all we need irrespective of the dining room’s size. And I can tell you from personal experience a king bed sleeps as well in a cramped room as it does in a palatial suite.
I remember one of my trips to NYC, while on a visit with Lyric HiFi owner Mike Kay. He took me to an old Brownstone somewhere on the city’s West Side to visit an IRSV owner. To my surprise, the giant 4-piece Infinity speaker system dominated their tiny living room to such a degree that the owners had to walk between the midrange and woofer towers to access their upstairs bedroom. The beasts consumed 80% of their living room and looked absurdly out of place to me, but oh man did they sing! These were some of the finest sounds I had ever heard from a pair of the massive speakers—almost as nice as another tiny room filled with them at the home of the Absolute Sound Magazine’s publisher, Harry Pearson.
With common sense boundaries in mind, I am calling this one fiction.
