Down firing sub tweeks

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.

Similar to Roofmeister, I built my equipment table and amp platform gluing three sheets of 3/4" MDF and trimmed with stained poplar. I'm very satified. Have some pieces remaining and I'll also report back how it works under my REL. The spikes are reasonable from Parts Express. I was going to take the same approach for platforms to support a set of Snell D's that I recently came across.

Well I finished the sub bases, and after an evening of listening here are my thoughts:
-Well worth doing if you have carpet. Bass is clear, and
tight. The carpet seemed to muffle the sound some.
- My room is a finished room over the garage, and if you are looking to this idea to keep the sound in rooms below you quieter, it will do that also. But, you can still hear it below, but definatly not as loud.
- Thanks for the info. on the spikes from Parts express, I will order those as I believe this tweek is a success.
You can see them in my system photo.
