How important is the speaker/room interface?


In my years in this hobby, I've come to believe the speaker/room interface is one of the most important elements we face in building a satisfying audio system. And while it seems there is a growing realization of this point (emphasis on speaker placement and room design), I don't believe it yet receives the attention it deserves. For example, some folks who have never addressed the sonics of their listening rooms may spend weeks and significant money trying out different wires when a different speaker system and/or room treatments could provide far greater sonic improvements.

I have three friends who have the same make/model speaker as I own. I've listened to each of them with the same or similar amps, yet the sonic results are significantly different. The primary difference is the rooms -- volume, shape, construction, decoration, etc. So while I've made adjustments in my own speaker/room to improve it to a reasonable extent, I know my speakers could sound better in a more optimized room based on this experience. No change of sources, electronics, wires, tweaks, etc. could effect as much difference.

I'm thinking about this now since I just read the HFN history in "Sound Bites" by Kessler and Harris. In a 1994 interview by Ken Kessler with Peter Walker, Walker is ask what he believes still needs to be addressed in audio. His first response is the relationship of the speaker and room.

So, any thoughts as to why the speaker/room interface is not more universally considered the top priority in building a system?

The speakers and the room essentially form an acoustical circuit. Approximately 50% of the sound we hear is indirect--bouncing off other surfaces or pressurizing due to room boundaries. Their interaction is huge. Have you ever heard a speaker that is way too big in a small room? Sound boomy and completely out of balance. Likewise, a small monitor in a very large room will sound anemic.

Any type of equalization (digital or analog) should be done as the last step. The corrections have their own issues, which I won't go into, but suffice to say the best EQ is no EQ if and only if you can get a proper response without it. If you can't then EQ can be a valuable tool to fine tuning, but don't try to ignor the room thinking that EQ can solve all woes--it can't.

Simple and most important things to do is first have appropriate speakers for the room (size wise), second be able to place them and the listener in good locations for best performance, third install the appropriate acoustical treatment (it can be concealed visually), and lastly use an EQ to touch up what might not have been possible by acoustical treatment (almost always in the bass from boundary conditions that can not be changed).
