Bass and the REQ room simulator


I'm a little embarrassed to state that I only learned about a cool feature of the Room EQ Wizard.

Now you can do room bass simulation.  The tool lets you draw a rectangular (sorry, no others) room, and it will simulate the effects of the room modes given a specified listening location and acoustic materials.

This has a number of practical and educational uses.  For instance, instead of doing the sub crawl, you can use the simulator to optimize your sub placement or listening location.  A big win if you have a 100lb sub. You can also, to some degree, simulate the benefits of bass traps or using multiple subs.

Hopefully a lot of what-if situations we regularly get asked in Audiogon can be answered there, allowing the user to try out their ideas, regarding questions about adding more subs, or room treatement, or placement options.

Specific information is here:

Hopefully it will help illustrate just why bass is in fact so difficult for most audiophiles, and  why so many would rather have a smaller speaker than attempt bottom octave bass.

if you choose  miniDSP UMIK-1 calibrated USB measurement microphone ,you dont need additional USB interface 
especially for crossover less full range  , but this guys dont believed in any measurement , just trust own ears   
Hi @Bache
That's good to know, but we're talking about simulation, not measurement. :)

one more less  expensive way to compensate any loudspeakers and room treatment issues. one time provide measurement, you can see any picks and holes and use old fashion, equalizer. Some brands , i dont want to mention offer very chip microphone and electronic device , played equalizer role , but called different name and selling for huge money 
Hi @bache
I did not mean to start a thread on how to make your room better. :)

I just wanted to show how this tool is interesting and how you can use it to learn or place a sub.

Best,

Erik
