So sub or not to sub

Bob and Wolf, been thinking about some basement/sound room mods. Not much I can do about speaker placement, but was thinking about using corkwood panels to absorb resonant bass nodes. Are you familiar with sound absorbing decorative wall materials that may take the edge off some bass ringing? One problem area is that my wife hung wall pictures. The pics vibrate at certain frequencies. Was thinking the corkwood might at least deaden some of those vibrations. Suggestions???

Btw, my wife demurred to allowing me to install some dedicated electric circuits. I may run 3 or 4 dedicated romex lines, which would include a 10 to 12 gauge circuit just for the amp. That may be a big help.

Thanks

Bruce

I stick little rubber feet under the lower corners of wall art, otherwise the furniture seems to control things somewhat. Bass frequencies are longer sound waves that are harder to wrangle, but I do know that tube traps of some sort can work if needed.
