Down firing sub tweeks

PTM, this is interesting as I'm always looking to experiment. Is the sub simply sitting on the floor or did you fashion some type of feet?

Just sitting on the carpet in my room, so it doesn't scratch.

I have a 3 inch thick maple cutting board. Think I'll give it a try.

I decided to try and experiment with sub bases. I made them out of (2) 3/4" thich MDF glued and screwed together. I then glued on 1/2" oak plywood for a 2" total thickness. I wrapped the out side edges with aspen wood all stained to match the componet stand I built previously. Not willing to spend big bucks on cones at this point I used 3" x 5/16" brass screws that extend 1" below the bottom for spikes. Once the 5 coats of gloss clearcoat set up I will try them out and report on any impressions.

That sounds like a great platform. Cones from parts express are not expensive. But you will get a idea at what the platform will sound like.
