I attempted to plot the response of three different subs. REW output connected to the CD input on receiver. Sub - Yes. Mains - Large. (Mains disconnected.) My room is quite large, but the lack of bass below 35hz seems rather exaggerated. I'm hoping I have made an error in the setup somehow.
I profiled the sound (rather old onboard audio) saved the cal and then loaded the RS meter cal. The waterfall for the sound card was curved below 40hz. Maybe its a problem?
Also, the waterfalls don't seem to scale properly on the X-axis. If I zoom in and out, the graphed data seems to expand and contract totally different than the axis. i.e. A 3D plot originally went 10-120hz, I zoom in and back out, now the 3D plot shows 10-200hz, etc. each time I do it the data changes scale.
edit: The waterfall shown is from the 3rd sub, CSX-15 shown in teal.
Sorry to include so many goofups in one post!
