I was laying on the floor next to one of my subs while the music was playing and could feel vibrations from my janis subs. Also the cables are directed out of the bottom of my sub. A quick check of the Soundanchor website and Alberporter revealed that they have stock stands for subs and also make cutom stands.
I contacted them. Sent them the measurements for my speakers. Sometime later a set of stands arrived via UPS.
Problem solved. Carpet no longer vibrates and the sub is no longer sitting on the cables. The bass has tightend up considerably.
BTW I support and encourage DIY solutions to problems like this.
