So I simulated bass traps as best as I could. You can see pictures of the mess I created in my basement below. I even managed to get carpet from one of my neighbors. Randy, my wife is really PO'd at you because I told her this was your idea .

The blue trace in the graph is no treatments with a 40Hz cut-off. The red trace is with the treatments and an 80Hz cut-off. I've explained what the 80Hz cut-off does in other posts. The bottom line is that the treatments really amounted to nothing in the frequency domain.

However, the time domain is a different issue. I don't hear as sharp a "snap" after I finish clapping my hands. Also, I can turn the volume up higher before sound starts to get muddied. And there is no question that the bass is tighter!

Maybe I will go for some artificial treatments after all .
