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. 

I have a rug on the concrete floor and ensure no chair upholstery is behind my head. Records and wood break up reflections in the corner. Not being in a small closed room helps.

To me, bass trapping is about decay time. 
The idea of producing sound, and then controling it was very foreign to me in the beginning, once you understand reflection points, flutter echo, standing waves, those are common issues in dedicated HT’s.

i never measured before implementing the corner traps :0/  so definitely i cannot show you proof on paper, maybe when im retired and project hunting, i’ll pull em out and plot some graphs....

theres no doubt about the bass decay, i find it very acceptable 

For me, it was “wow, this completely transformed the low end and was more than worth every dollar spent.” It made more difference to the sound in my old room than spending 3x the money on speakers. And the new room, being well sealed and in the basement, was a hopeless echo chamber without bass trapping.

And in cleaning up the low end, you should get far more clarity across the rest of the band.
