avantgarde duo spikes or plastic feet ?

Hi there,

I would welcome any views from Uno/Duo owners on whether it is best to use the woofer spikes or the 3 plastic feet (or combination of both) on a concrete floor?

I currently use just the 3 plastic feet but the amount of energy transmitted to the mid-horn casing seems quite significant. I was therefore thinking that some sort of spike/grounding arrangement for the woofer ought to be a good idea. Or perhaps has anyone tried damping the unit with something and achieved interesting results?

Both feet and spikes will transfer energy to the horns. Try keeping all the bolts loose. This will tranfer less energy. You may get slightly better bass with the spikes

The spikes (if they're any good) will transfer the resonance energy into the flooring system which is a very good thing. The plastic feet, on the other hand, are of no use.

Ensure all bolts taught or tighter, otherwise the vibrations will become trapped as a result of inferior or loose mechanical connections and since those vibrations (captured in a moment in time) would have nowhere to go, they can only dissipate over an extended period of time and exponentiate because of the poor connections. Sonically, this is not a good thing.

Some guys use 3 Black Diamond Racing cones under the subs, lifting them off their feet.
