To those who support idea a room isn't large enuff

In my reading in the forums I have read at various threads and just didn't want to say anything at the time for fear of starting a riff with someones belief that a small room size can be a constraint to "it not being capable of supporting a low frequency note".

A little background on myself regarding low frequency reproduction. Not a professional speaker/subwoofer builder. Read and reread Vance Dickinson? Loudspeaker Cookbook. Designed and built a few/some sub systems.My favorite and what I considered the most accurate sub was a sealed enclosure with what I believe was a passive device made by one of the Danish driver manufactures. It fit into a hole apprx. 3.5" in diameter to only cover the hole with a type of acoustic fiber that was apprx. 3/8"-1/2" thick.Its purpose was to help smooth out the impedance curve the amp would see, from the driver thru the negative side of the sub. Pls. correct me on that last sentence if I have forgotten more than I remember.

Without going into great detail and possibly causing any confusion, I'll use the best illustration I know of that's simple to debunk those that believe in the aforementioned.

When a sub system is built for an automobile and you play music/sinewaves or what have you, it will reproduce 20/30/40 hz without constraints as long as you have the system capabilities. I've felt a 20-30 hz signal reproduced in an autimobile that I wouldn't have thought capable at the SPL's I heard and felt.In actuality I have ran a cd with stepped frequency tones. And from 20 - 100 hz I got the strongest tones bursts between 30 and 50 hz.With music the bass guitar sounded full and robust.Kinda like the bass my Apogee Stages put out.

JUst my thoughts on the subject. Pls. feel free to offer your take and why you may feel differently.

Standing waves and room nodes should be more of an issue in bass response than room size. If you can control these with room treatment or speaker placement, then you are golden.

However, with that being said, bass response is not the only issue one faces when shoehorning large speakers into small spaces. Other frequency anomolies can materialize from early reflections. And imaging/soundstaging will be constrained in smaller spaces. Bottom line is match the speaker to the size room it will be housed in. Many people ignore this advice.
