Soundwave properties, looking for answers.


Trying to better understand how soundwaves travel, reflect, get absorbed and transmit.
I am looking to improve my listening room's acoustics. I would like to do something to my side walls to stop the bass from passing through and also to contain the bass or better yet to get the bass to reach me in my listening sweet spot and not the corners where I hear them much more than in my listening position. Also how do I stop bass from reaching my neighbors living space?
I also am thinking of building a corner just behind both of my main speakers in hope of increasing the bass heard from them. Will this work and what material do I use? I was thinking of concrete thinking that it is the only material that stops bass and reflects it am I right? I would make that corner stand 3 or 4 inches behind and to the side of the speaker on the outside side. Just like how subs sound louder when placed in corners I am hoping this increases the sound of the lower frequencies from the mains.
Any help is welcomed, thanks.

The bass will always be strongest in the corners and near walls. The less leaky of bass -- i.e., the more solid -- your walls are, the more this will be true. Without pretending that I can suggest just what you should do and how you should do it, the general idea is to experiment with your listening position and speaker positioning to try and find another 'sweet spot' that has better overall bass response. Short of electronic equalization, repositioning is really the only way to improve weak perceived bass response. It's a common dilemma that best (strongest, most even) bass response is pretty frequently at odds with best imaging/soundstaging (as well as best midrange response) when trying to locate real speakers and real listeners within real rooms, where practical choices are often limited.
