Last night, I ended up picking some Mirage OM6 speakers up off craigslist for a great price for a floorstanding 2.0 setup. These will be going in my apartment in about a month once I move in. The living room floor is carpeted.
It might be worth considering that the speakers are fairly unique, at the bottom of the tower they have an 150W amp driving an 8" sub with a passive radiator, and on the top they have a 1" tweeter with 5.5" woofer, on each side of the tower. The rear is designed to be pointed into a corner so they radiate into a room.

My question is would it be better to use spikes to couple them to the floor, and for stability? Or, should I use a foam riser to isolate them? I'm worried if I couple them I would end up transmitting some bass to all my neighbors.
