Auralex SubDude

I used two of them under my old speakers because of floor vibration and they worked awesome. Still have one and gave the other to my brother in law because he's a guiatrist and plays some gigs on raised floors. He loves the thing.

I used a similar Auralex Gramma under a Vel DD-15 for a time. It is effective in isolating the room from the sub, but not much good in communicating LF with precision. A Star Sound SP-1 with Audiopoints brass cups gives more delineation in the sub bass region and reduces muddiness that cabinet resonances will otherwise introduce into the upper bass and midrange.

Interesting. I need to do more listening. I think I might experiment by putting some weight on top of the sub to damp the movement a little. I've heard people putting bags of lead shot on top of subs.

On the subject of monitors, has anyone tried the Auralex Mopads? I've read mixed reviews. Some people seem to prefer the Primacoustic recoil stabilizer. Unfortunately, due to decorating factors and a small house, my monitors are on a built-in MDF cabinet. It's extremely solid, but it is coloring the sound somewhat.

Mateored, rather than lead shot, you might try a bag of microbearing steel from eBay or a foundry supply company. I use this inside the enclosure and in an ultrasuede bag placed on top of my modified Merlin VSMs. The Merlin is particularly active with vibration across the top of its cabinet. Microbearing steel is more reactive than lead shot in absorbing vibration and is of course non-toxic.

Several years ago I got a fairly inexpensive 1x10 powered sub. I felt it could play cleaner. I had a slab of granite I had gotten from a Tandy store (just $20) for leatherworking. I placed the slab on the subwoofer (with a layer of shock-absorbing shelf liner in between) and voila! It made the bass much cleaner and more linear-sounding.
