Equipment Location at First Reflection Point

A recent discussion on speaker positioning also had comments about where to place equipment.  Due to multiple door/window/furniture constraints,  the only configuration that works is to place the equipment on the right side wall.  However, to avoid bass modes the only location on the sidewall is at the first reflection point.  I've searched the forums for comments about this (as well as Smith's book) and found nothing that addresses whether or not this is a problem.  Just wondering whether this is an issue and, if so, how would you address it ?

If you cannot find that test cd, you could send me a private message about it.

it never occurred to me to use a SPL meter to refine the search for the G spot. I think they have missed a marketing opportunity!

Do yourself a lifetime favor, get one of these Sound Pressure Meters

 

needs a tripod hole on the bottom. Tripod, seated ear height, listening position

Next, you need test signals to measure/compare.

this CD is my favorite: tracks 9-38: 29 individually selectable 1/3 octave bands,

 

make a chart, see what you are getting, see results of changes.

My vintage speakers have level controls, and this was my new best friend balancing side to side and top to bottom from my listening position.

 

I'm restoring a vintage pair of AR-2ax speakers for my office, finishing today. I had forgotten they have mid and tweet level controls. Mic and test tones tomorrow am. Usually you let the woofer go full out and apply less or more attenuation to the other drivers, relative to what the woofer is doing IN IT'S CURRENT POSITION. Move them, readjust. Oh happy day, BUT, be precise! You might consider, if you have too much bass GENERALLY, add a level control to tame whatever needed.
