Tell us about your acoustic treatments

Can someone who has done extensive bass trapping chime in on the significance of the treatment. Was it a “yeah, that’s better,” or was it a “wow, this completely transformed the low end and was more than worth every dollar spent.” It’s seems to me that proper bass trapping requires lots of treatment and significant investment. I would like to know if it’s really worth the effort before I start down that path. 

Thanks Mike. I’m not familiar with all the products you use. Is it mainly absorptive bass traps? Any limp membranes? Tuned traps? Resonators?

Thanks for the reply. I’ll have to check out that adjustable bass trap. It makes a lot of sense. One of these days I will build or buy some traps. I use DSP which really helps. I wonder if you can reduce the number of bass traps you need by adding more and more subwoofers and using DSP. What are the odds you can reduce the number of traps required to zero with a well tuned distributed bass array?
