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.

PS - I encourage everyone to play with it, it’s a great great learning tool and the more we have trying it out, the better.

It does support up to 4 subs, so I’m sure the swarm people will go nuts with it. That’s fine. This is exactly the place for it.  So long as any poster is respectful of the fact that there are multiple ways to get good bass, and different priorities for buyers I do not have a problem with it.

I haven’t tried this part of REW it’s hard enough learning the basics. I will say I don’t use traditional subwoofers thinking about it though but my speakers will go to 35hz pretty flat until they roll off to 24hz. Dutch and Dutch 8c. I am running 5 filters below 200hz. Good info to know thanks

The room simulator will do normal speakers too, and you can put in your cut offs to see how different main speakers would behave.

I suspect a lot of people will be really surprised what happens when you go from a two way to a full-range, multi-way and how bad it can be.
